129 | mikedld | 1 | SYSTEM FUNCTIONS of OS Kolibri 0.5.8.1 |
2 | |||
3 | Number of the function is located in the register eax. |
||
4 | The call of the system function is executed by "int 0x40" command. |
||
5 | All registers except explicitly declared in the returned value, |
||
6 | including eflags, are preserved. |
||
7 | |||
8 | |||
9 | ====================================================================== |
||
10 | ============== Function 0 - define and draw the window. ============== |
||
11 | ====================================================================== |
||
12 | Defines an application window. Draws a frame of the window, header and |
||
13 | working area. For windows with skin defines standard buttons for close |
||
14 | and minimize. |
||
15 | Parameters: |
||
16 | * eax = 0 - function number |
||
17 | * ebx = [coordinate on axis x]*65536 + [size on axis x] |
||
18 | * ecx = [coordinate on axis y]*65536 + [size on axis y] |
||
19 | * edx = 0xXYRRGGBB, where: |
||
20 | * Y = style of the window: |
||
21 | * Y=0 - type I - window of the fixed size |
||
22 | * Y=1 - only define window area, draw nothing |
||
23 | * Y=2 - type II - window of the variable size |
||
24 | * Y=3 - window with skin |
||
25 | * other possible values (from 4 up to 15) are reserved, |
||
26 | function call with such Y is ignored |
||
27 | * RR, GG, BB = accordingly red, green, blue components of a color |
||
28 | of the working area of the window (are ignored for style Y=2) |
||
29 | * X = DCBA (bits) |
||
30 | * A = 1 - window has caption; for style Y=3 caption string |
||
31 | must be passed in edi, for other styles use |
||
32 | subfunction 1 of function 71 |
||
33 | * B = 1 - coordinates of all graphics primitives are relative to |
||
34 | window client area |
||
35 | * C is reserved (set to 0) |
||
36 | * D = 0 - normal filling of the working area, 1 - gradient |
||
37 | The following parameters are intended for windows |
||
38 | of a type I and II, and ignored for styles Y=1,3: |
||
39 | * esi = 0xXYRRGGBB - color of the header |
||
40 | * RR, GG, BB define color |
||
41 | * Y=0 - usual window, Y=1 - unmovable window |
||
42 | * X defines a gradient of header: X=0 - no gradient, |
||
43 | X=8 - usual gradient, |
||
44 | for windows of a type II X=4 - negative gradient |
||
45 | * other values of X and Y are reserved |
||
46 | * edi = 0x00RRGGBB - color of the frame |
||
47 | Returned value: |
||
48 | * function does not return value |
||
49 | Remarks: |
||
50 | * Position and sizes of the window are installed by the first |
||
51 | call of this function and are ignored at subsequent; to change |
||
52 | position and/or sizes of already created window use function 67. |
||
53 | * For windows with style Y=3 and caption (A=1) caption string is set |
||
54 | by the first call of this function and is ignored at subsequent |
||
55 | (strictly speaking, is ignored after a call to subfunction 2 |
||
56 | of function 12 - end redraw); to change caption of already created |
||
57 | window use subfunction 1 of function 71. |
||
58 | * If the window has appropriate styles, position and/or sizes can be |
||
59 | changed by user. Current position and sizes can be obtained |
||
60 | by function 9. |
||
61 | * The window must fit on the screen. If the transferred |
||
62 | coordinates and sizes do not satisfy to this condition, |
||
63 | appropriate coordinate (or, probably, both) is considered as zero, |
||
64 | and if also it does not help, the appropriate size |
||
65 | (or, probably, both) is installed in a size of the screen. |
||
66 | |||
67 | Further we shall designate xpos,ypos,xsize,ysize - values |
||
68 | transmitted in ebx,ecx. The coordinates are resulted concerning |
||
69 | the left upper corner of the window, which, thus, is set as (0,0), |
||
70 | coordinates of the right lower corner essence (xsize,ysize). |
||
71 | * The sizes of the window are understood in sence of coordinates |
||
72 | of the right lower corner. This concerns all other functions too. |
||
73 | It means, that the real sizes are on 1 pixel more. |
||
74 | * The window of type I looks as follows: |
||
75 | * draw external frame of color indicated in edi, 1 pixel in width |
||
76 | * draw header - rectangle with the left upper corner (1,1) and |
||
77 | right lower (xsize-1,min(25,ysize)) color indicated in esi |
||
78 | (taking a gradient into account) |
||
79 | * if ysize>=26, fill the working area of the window - |
||
80 | rectangle with the left upper corner (1,21) and right lower |
||
81 | (xsize-1,ysize-1) (sizes (xsize-1)*(ysize-21)) with color |
||
82 | indicated in edx (taking a gradient into account) |
||
83 | * if A=1 and caption has been already set by subfunction 1 |
||
84 | of function 71, it is drawn in the corresponding place of header |
||
85 | * The window of style Y=1 looks as follows: |
||
86 | * completely defined by the application |
||
87 | * The window of type II looks as follows: |
||
88 | * draw external frame of width 1 pixel with the "shaded" color |
||
89 | edi (all components of the color decrease twice) |
||
90 | * draw intermediate frame of width 3 pixels with color edi |
||
91 | * draw internal frame of width 1 pixel with the "shaded" color edi |
||
92 | * draw header - rectangle with the left upper corner (4,4) |
||
93 | and right lower (xsize-4,min(20,ysize)) color, indicated in esi |
||
94 | (taking a gradient into account) |
||
95 | * if ysize>=26, fill the working area of the window - |
||
96 | rectangle with the left upper corner (5,20) and right lower |
||
97 | (xsize-5,ysize-5) with color indicated in edx |
||
98 | (taking a gradient into account) |
||
99 | * if A=1 and caption has been already set by subfunction 1 |
||
100 | of function 71, it is drawn in the corresponding place of header |
||
101 | * The skinned window looks as follows: |
||
102 | * draw external frame of width 1 pixel |
||
103 | with color 'outer' from the skin |
||
104 | * draw intermediate frame of width 3 pixel |
||
105 | with color 'frame' from the skin |
||
106 | * draw internal frame of width 1 pixel |
||
107 | with color 'inner' from the skin |
||
108 | * draw header (on bitmaps from the skin) in a rectangle |
||
109 | (0,0) - (xsize,_skinh-1) |
||
110 | * if ysize>=26, fill the working area of the window - |
||
111 | rectangle with the left upper corner (5,_skinh) and right lower |
||
112 | (xsize-5,ysize-5) with color indicated in edx |
||
113 | (taking a gradient into account) |
||
114 | * define two standard buttons: for close and minimize |
||
115 | (see function 8) |
||
116 | * if A=1 and edi contains (nonzero) pointer to caption string, |
||
117 | it is drawn in place in header defined in the skin |
||
118 | * value _skinh is accessible as the result of call |
||
119 | subfunction 4 of function 48 |
||
120 | |||
121 | ====================================================================== |
||
122 | ================ Function 1 - put pixel in the window. =============== |
||
123 | ====================================================================== |
||
124 | Parameters: |
||
125 | * eax = 1 - function number |
||
126 | * ebx = x-coordinate (relative to the window) |
||
127 | * ecx = y-coordinate (relative to the window) |
||
128 | * edx = 0x00RRGGBB - color of a pixel |
||
129 | edx = 0x01xxxxxx - invert color of a pixel |
||
130 | (low 24 bits are ignored) |
||
131 | Returned value: |
||
132 | * function does not return value |
||
133 | |||
134 | ====================================================================== |
||
135 | ============ Function 2 - get the code of the pressed key. =========== |
||
136 | ====================================================================== |
||
137 | Takes away the code of the pressed key from the buffer. |
||
138 | Parameters: |
||
139 | * eax = 2 - function number |
||
140 | Returned value: |
||
141 | * if the buffer is empty, function returns eax=1 |
||
142 | * if the buffer is not empty, function returns al=0, |
||
143 | ah=code of the pressed key, high word of eax is zero |
||
144 | * if there is "hotkey", function returns al=2, |
||
145 | ah=scancode of the pressed key (0 for control keys), |
||
146 | high word of eax contains a status of control keys at the moment |
||
147 | of pressing a hotkey |
||
148 | Remarks: |
||
149 | * There is a common system buffer of the pressed keys |
||
150 | by a size of 120 bytes, organized as queue. |
||
151 | * There is one more common system buffer on 120 "hotkeys". |
||
152 | * If the application with the inactive window calls this function, |
||
153 | the buffer of the pressed keys is considered to be empty. |
||
154 | * By default this function returns ASCII-codes; to switch |
||
155 | to the scancodes mode (and back) use function 66. |
||
156 | However, hotkeys are always notificated as scancodes. |
||
157 | * To find out, what keys correspond to what codes, start |
||
158 | the application keyascii and scancode. |
||
159 | * Scancodes come directly from keyboard and are fixed; |
||
160 | ASCII-codes turn out with usage of the conversion tables, |
||
161 | which can be set by subfunction 2 of function 21 |
||
162 | and get by subfunction 2 of function 26. |
||
163 | * As a consequence, ASCII-codes take into account current |
||
164 | keyboard layout (rus/en) as opposed to scancodes. |
||
165 | * This function notifies only about those hotkeys, which were |
||
166 | defined by this thread by subfunction 4 of function 66. |
||
167 | |||
168 | ====================================================================== |
||
169 | ==================== Function 3 - get system time. =================== |
||
170 | ====================================================================== |
||
171 | Parameters: |
||
172 | * eax = 3 - function number |
||
173 | Returned value: |
||
174 | * eax = 0x00SSMMHH, where HH:MM:SS = Hours:Minutes:Seconds |
||
175 | * each item is BCD-number, for example, |
||
176 | for time 23:59:59 function returns 0x00595923 |
||
177 | Remarks: |
||
178 | * See also subfunction 9 of function 26 - get time from |
||
179 | the moment of start of the system; it is more convenient, because |
||
180 | returns simply DWORD-value of the time counter. |
||
181 | * System time can be set by function 22. |
||
182 | |||
183 | ====================================================================== |
||
184 | ============ Function 4 - draw text string in the window. ============ |
||
185 | ====================================================================== |
||
186 | Parameters: |
||
187 | * eax = 4 - function number |
||
188 | * ebx = [coordinate on axis x]*65536 + [coordinate on axis y] |
||
189 | * ecx = 0xX0RRGGBB, where |
||
190 | * RR, GG, BB specify text color |
||
191 | * X specifies the used font: 0=system monospaced, |
||
192 | 1=system font of variable width |
||
193 | * edx = pointer to the beginning of the string |
||
194 | * esi = length of the string, must not exceed 255 |
||
195 | Returned value: |
||
196 | * function does not return value |
||
197 | Remarks: |
||
198 | * Function outputs either first (esi and 0xFF) characters or |
||
199 | all characters before (but not including) terminating zero |
||
200 | (for ASCIIZ-strings) depending on what occurs first. |
||
201 | * First system font is read out at loading from the file char.mt, |
||
202 | second - from char2.mt. |
||
203 | * Both fonts have height 9 pixels, width of the monospaced font |
||
204 | is equal to 6 pixels. |
||
205 | |||
206 | ====================================================================== |
||
207 | ========================= Function 5 - delay. ======================== |
||
208 | ====================================================================== |
||
209 | Delays execution of the program on the given time. |
||
210 | Parameters: |
||
211 | * eax = 5 - function number |
||
212 | * ebx = time in the 1/100 of second |
||
213 | Returned value: |
||
214 | * function does not return value |
||
215 | Remarks: |
||
216 | * Passing ebx=0 does not transfer control to the next process |
||
217 | and does not make any operations at all. If it is really required |
||
218 | to transfer control to the next process (to complete a current |
||
219 | time slice), use subfunction 1 of function 68. |
||
220 | * At current implementation there will be an immediate return from |
||
221 | the function, if the addition of ebx with current value of |
||
222 | time counter will call 32-bit overflow. |
||
223 | |||
224 | ====================================================================== |
||
225 | ============== Function 6 - read the file from ramdisk. ============== |
||
226 | ====================================================================== |

228 | * eax = 6 - function number |
||
229 | * ebx = pointer to the filename |
||
230 | * ecx = number of start block, beginning from 1; |
||
231 | ecx=0 - read from the beginning of the file (same as ecx=1) |
||
232 | * edx = number of blocks to read; |
||
233 | edx=0 - read one block (same as edx=1) |
||
234 | * esi = pointer to memory area for the data |
||
235 | Returned value: |
||
236 | * eax = file size in bytes, if the file was successfully read |
||
237 | * eax = -1, if the file was not found |
||
238 | Remarks: |
||
239 | * This function is out-of-date; function 70 allows |
||
240 | to fulfil the same operations with the extended possibilities. |
||
241 | * Block = 512 bytes. |
||
242 | * For reading all file you can specify the certainly large value |
||
243 | in edx, for example, edx = -1; but in this case be ready that |
||
244 | the program will "fall", if the file will appear too large and can |
||
245 | not be placed in the program memory. |
||
246 | * The filename must be either in the format 8+3 characters |
||
247 | (first 8 characters - name itself, last 3 - extension, |
||
248 | the short names and extensions are supplemented with spaces), |
||
249 | or in the format 8.3 characters "FILE.EXT"/"FILE.EX " |
||
250 | (name no more than 8 characters, dot, extension 3 characters |
||
251 | supplemented if necessary by spaces). |
||
252 | The filename must be written with capital letters. The terminating |
||
253 | character with code 0 is not necessary (not ASCIIZ-string). |
||
254 | * This function does not support folders on the ramdisk. |
||
255 | |||
256 | ====================================================================== |
||
257 | =============== Function 7 - draw image in the window. =============== |
||
258 | ====================================================================== |
||
259 | Paramters: |
||
260 | * eax = 7 - function number |
||
261 | * ebx = pointer to the image in the format BBGGRRBBGGRR... |
||
262 | * ecx = [size on axis x]*65536 + [size on axis y] |
||
263 | * edx = [coordinate on axis x]*65536 + [coordinate on axis y] |
||
264 | Returned value: |
||
265 | * function does not return value |
||
266 | Remarks: |
||
267 | * Coordinates of the image are coordinates of the upper left corner |
||
268 | of the image relative to the window. |
||
269 | * Size of the image in bytes is 3*xsize*ysize. |
||
270 | |||
271 | ====================================================================== |
||
272 | =============== Function 8 - define/delete the button. =============== |
||
273 | ====================================================================== |
||
274 | Parameters for button definition: |
||
275 | * eax = 8 - function number |
||
276 | * ebx = [coordinate on axis x]*65536 + [size on axis x] |
||
277 | * ecx = [coordinate on axis y]*65536 + [size on axis y] |
||
278 | * edx = 0xXYnnnnnn, where: |
||
279 | * nnnnnn = identifier of the button |
||
280 | * high (31st) bit of edx is cleared |
||
281 | * if 30th bit of edx is set - do not draw the button |
||
282 | * if 29th bit of edx is set - do not draw a frame |
||
283 | at pressing the button |
||
284 | * esi = 0x00RRGGBB - color of the button |
||
285 | Parameters for button deleting: |
||
286 | * eax = 8 - function number |
||
287 | * edx = 0x80nnnnnn, where nnnnnn - identifier of the button |
||
288 | Returned value: |
||
289 | * function does not return value |
||
290 | Remarks: |
||
291 | * Sizes of the button must be more than 0 and less than 0x8000. |
||
292 | * For windows with skin definition of the window |
||
293 | (call of 0th function) creates two standard buttons - |
||
294 | for close of the window with identifier 1 and |
||
295 | for minimize of the window with identifier 0xffff. |
||
296 | * The creation of two buttons with same identifiers is admitted. |
||
297 | * The button with the identifier 0xffff at pressing is interpreted |
||
298 | by the system as the button of minimization, the system handles |
||
299 | such pressing independently, not accessing to the application. |
||
300 | In rest it is usual button. |
||
301 | * Total number of buttons for all applications is limited to 4095. |
||
302 | |||
303 | ====================================================================== |
||
304 | ============ Function 9 - information on execution thread. =========== |
||
305 | ====================================================================== |
||
306 | Parameters: |
||
307 | * eax = 9 - function number |
||
308 | * ebx = pointer to 1-Kb buffer |
||
309 | * ecx = number of the slot of the thread |
||
310 | ecx = -1 - get information on the current thread |
||
311 | Returned value: |
||
312 | * eax = maximum number of the slot of a thread |
||
313 | * buffer pointed to by ebx contains the following information: |
||
314 | * +0: dword: usage of the processor (how many time units |
||
315 | per second leaves on execution of this thread) |
||
316 | * +4: word: position of the window of thread in the window stack |
||
317 | * +6: word: (has no relation to the specified thread) |
||
318 | number of the thread slot, which window has in the window stack |
||
319 | position ecx |
||
320 | * +8: word: reserved |
||
321 | * +10 = +0xA: 11 bytes: name of the process |
||
322 | (name of corresponding executable file in the format 8+3) |
||
323 | * +21 = +0x15: byte: alignment, this byte preserves |
||
324 | * +22 = +0x16: dword: address of the process in memory |
||
325 | * +26 = +0x1A: dword: size of used memory - 1 |
||
326 | * +30 = +0x1E: dword: identifier (PID/TID) |

||
330 | * +46 = +0x2E: dword: size of the thread window on axis y |
||
331 | * +50 = +0x32: word: status of the thread slot: |
||
332 | * 0 = thread is running |
||
333 | * 1 = thread is suspended |
||
334 | * 2 = thread is suspended while waiting for event |
||
335 | * 3 = thread is terminating as a result of call to function -1 |
||
336 | or under duress as a result of call to subfunction 2 |
||
337 | of function 18 or termination of the system |
||
338 | * 4 = thread is terminating as a result of exception |
||
339 | * 5 = thread waits for event |
||
340 | * 9 = requested slot is free, all other information on the slot |
||
341 | is not meaningful |
||
342 | Remarks: |
||
343 | * Slots are numbered starting from 1. |
||
344 | * Returned value is not a total number of threads, because there |
||
345 | can be free slots. |
||
346 | * When process is starting, system automatically creates |
||
347 | execution thread. |
||
348 | * Function gives information on the thread. Each process has |
||
349 | at least one thread. One process can create many threads, |
||
350 | in this case each thread has its own slot and the fields |
||
351 | +10, +22, +26 in these slots coincide. |
||
352 | Applications have no common way to define whether two threads |
||
353 | belong to one process. |
||
354 | * The active window - window on top of the window stack - |
||
355 | receives the messages on a keyboard input. For such window |
||
356 | the position in the window stack coincides with returned value. |
||
357 | * Slot 1 corresponds to special system thread, for which: |
||
358 | * the window is in the bottom of the window stack, the fields |
||
359 | +4 and +6 contain value 1 |
||
360 | * name of the process - "OS/IDLE" (supplemented by spaces) |
||
361 | * address of the process in memory is 0, size of used memory is |
||
362 | 16 Mb (0x1000000) |
||
363 | * PID=1 |
||
364 | * coordinates and sizes of the window are by convention set to 0 |
||
365 | * status of the slot is always 0 (running) |
||
366 | * the execution time adds of time leaving on operations itself |
||
367 | and idle time in waiting for interrupt (which can be got by call |
||
368 | to subfunction 4 of function 18). |
||
369 | * Beginning from slot 2, the normal applications are placed. |
||
370 | * The normal applications are placed in memory at the address |
||
371 | 0x10000000 (kernel constand 'std_application_base_address'). |
||
372 | There is no intersection, as each process has its own page table. |
||
373 | * At creation of the thread it is assigned the slot |
||

383 | * At the moment only the part of the buffer by a size |
||
384 | 52 = 0x34 bytes is used. Nevertheless it is recommended to use |
||
385 | 1-Kb buffer for the future compatibility, in the future |
||
386 | some fields can be added. |

1351 | as it a little where is used |
||
1352 | (day of week can be calculated by date). |
||
1353 | * Alarm clock can be set on operation in the given time every day. |
||
1354 | But there is no existing system function to disable it. |
||
1355 | * Operation of alarm clock consists in generation IRQ8. |
||
1356 | * Generally CMOS supports for alarm clock set of value 0xFF |
||
1357 | as one of parameters and it means that the appropriate parameter |
||
1358 | is ignored. But current implementation does not allow this |
||
1359 | (will return 1). |
||
1360 | * Alarm clock is a global system resource; the set of |
||
1361 | an alarm clock cancels automatically the previous set. |
||
1362 | However, at moment no program uses it. |

||
1376 | Remarks: |
||
1377 | * Only those events are taken into account, which enter into |
||
1378 | the mask set by function 40. By default it is |
||
1379 | redraw, key and button events. |
||
1380 | * To check for presence of a message in the queue use function 11. |
||
1381 | To wait without timeout use function 10. |
||
1382 | * Transmission ebx=0 results in immediate returning eax=0. |
||
1383 | * Current implementation returns immediately with eax=0, |
||
1384 | if the addition of ebx with the current value of time counter |
||
1385 | makes 32-bit overflow. |

1895 | ==================== Function 42 - read IRQ data. ==================== |
||
1896 | ====================================================================== |
||
1897 | When an IRQ occurs, the system reads data from ports indicated |
||
1898 | earlier by function 44 and writes this data to |
||
1899 | internal buffer. This function reads out data from that buffer |
||
1900 | bytewise. |
||
1901 | Parameters: |
||
1902 | * eax = 42 - function number |
||
1903 | * ebx = IRQ number, 0..15 |

1904 | Returned value: (use value of ecx to distinguish) |
||
1905 | * if the thread is not IRQ owner (or IRQ number is incorrect): |
||
1906 | * ecx = 2 |
||
1907 | * if there is no data: |
||
1908 | * eax = 0 |
||
1909 | * ecx = 1 |
||
1910 | * ebx destroyed |
||
1911 | * if all is ok: |

1912 | * eax = byte size of data, not yet read from buffer |
||
1913 | * ecx = 0 |
||
1914 | * ebx = current byte |
||
1915 | Remarks: |
||
1916 | * Previously the thread must reserve indicated IRQ for itself |
||
1917 | by function 45. |
||
1918 | * The size of data buffer is 4000 bytes, on overflow |
||
1919 | "fresh" data cease to be written in the buffer. |

1939 | Returned value: |
||
1940 | * eax = 0 - success, thus ebx = entered byte |
||
1941 | * eax = 1 - the thread has not reserved the selected port |
||
1942 | Remarks: |
||
1943 | * Previously the thread must reserve the selected port |
||
1944 | for itself by function 46. |
||
1945 | * Instead of call to this function it is better to use |
||
1946 | processor instructions in/out - this is much |
||
1947 | faster and a bit shorter and easier. |

1948 | |||
1949 | ====================================================================== |
||
1950 | =========== Function 44 - define operations at IRQ arrival. ========== |
||
1951 | ====================================================================== |
||
1952 | At IRQ arrival the system can read the data from ports defined |

1965 | Remarks: |
||
1966 | * Previously the thread must reserve for itself selected IRQ |
||
1967 | by function 45. |
||
1968 | * First 16 ports are considered only. |
||
1969 | * The current implementation considers incorrect value of field +3 |

||
1982 | or attempt to reserve not free IRQ |
||
1983 | or to free IRQ, not reserved by this thread) |
||
1984 | Remarks: |
||
1985 | * IRQ reservation is required for functions 42 and 44. |
||
1986 | * Only one thread can reserve the specific IRQ. |
||
1987 | * IRQs, handled by the system itself, are reserved by the system |
||
1988 | (thread 1) at booting. |
||
1989 | * When a thread terminates, all reserved by it IRQs |
||
1990 | are freed automatically. |

1993 | ====== Function 46 - reserve/free a group of input/output ports. ===== |
||
1994 | ====================================================================== |
||
1995 | To work with reserved ports an application can access directly by |
||
1996 | commands in/out (recommended way) and can use function 43 |
||
1997 | (not recommended way). |
||
1998 | Parameters: |
||
1999 | * eax = 46 - function number |
||
2000 | * ebx = 0 - reserve, 1 - free |

||
2003 | Returned value: |
||
2004 | * eax = 0 - success |
||
2005 | * eax = 1 - error |
||
2006 | Remarks: |
||
2007 | * For ports reservation: an error occurs if and only if |
||
2008 | one from the following condition satisfies: |
||
2009 | * start port is more than end port; |
||
2010 | * the selected range contains incorrect port number |
||
2011 | (correct are from 0 to 0xFFFF); |
||
2012 | * limit for the total number of reserved areas is exceeded |
||
2013 | (maximum 255 are allowed); |
||
2014 | * the selected range intersects with any of earlier reserved |
||
2015 | * For ports free: an error is an attempt to free range, |
||
2016 | that was not earlier reserved by this function |
||
2017 | (with same ecx,edx). |
||
2018 | * If an error occurs (for both cases) function performs no action. |
||
2019 | * At booting the system reserves for itself ports 0..0xff, and if |
||
2020 | COM-mouse is detected - additionally range of COM-ports |
||
2021 | 0x3f0..0x3ff and/or 0x2f0..0x2ff. |
||
2022 | * When a thread terminates, all reserved by it ports |
||
2023 | are freed automatically. |

2280 | =================== Function 50 - set window shape. ================== |
||
2281 | ====================================================================== |
||
2282 | Normal windows have rectangular shape. This function can give to |
||
2283 | a window any shape. The shape is given by a set of points inside |
||
2284 | the base rectangle belonging to a window. Position and coordinates |
||
2285 | of the base rectangle are set by function 0 |
||
2286 | and changed by function 67. |

2296 | -------------------------- Set shape scale --------------------------- |
||
2297 | Parameters: |
||
2298 | * eax = 50 - function number |
||
2299 | * ebx = 1 - subfunction number |
||
2300 | * ecx sets a scale: each byte of data defines |
||
2301 | (2^scale)*(2^scale) pixels |
||
2302 | Returned value: |
||
2303 | * function does not return value |
||
2304 | Remarks: |
||
2305 | * Default scale is 0 (scale factor is 1). If in the shape data |
||
2306 | one byte corresponds to one pixel, there is no necessity |
||
2307 | to set scale. |
||
2308 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2309 | pay attention, that they are one pixel more than defined by |
||
2310 | functions 0, 67. |
||
2311 | * On definition of scale xsize and ysize must be divisible |
||
2312 | on 2^scale. |
||
2313 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2314 | to a window of square with the side 2^scale (if scale=0, |
||
2315 | this is one pixel) and coordinates of the left upper corner |
||
2316 | (a mod (xsize shr scale), a div (xsize shr scale)) |
||
2317 | * Data size: (xsize shr scale)*(ysize shr scale). |
||
2318 | * Data must be presented in the memory and not change |
||
2319 | after set of shape. |
||
2320 | * The system views the shape data at every window redraw by |
||
2321 | function 0. |
||
2322 | * The call of subfunction 0 with NULL pointer results in return |
||
2323 | to the rectangular shape. |

2758 | * eax = 55 - error (speaker is off or busy) |
||
2759 | Data is an array of items with variable length. |
||
2760 | Format of each item is defined by first byte: |
||
2761 | * 0 = end of data |
||
2762 | * 1..0x80 = sets sound duration on 1/100 of second; sound note |
||
2763 | is defined by immediate value of frequency |
||
2764 | * following word (2 bytes) contains frequency divider; |
||
2765 | frequency is defined as 1193180/divider |
||
2766 | * 0x81 = invalid |
||
2767 | * 0x82..0xFF = note is defined by octave and number: |
||
2768 | * duration in 1/100 of second = (first byte)-0x81 |
||
2769 | * there is one more byte; |
||
2770 | * (second byte)=0xFF - delay |
||
2771 | * otherwise it looks like a*0x10+b, where b=number of the note in |
||
2772 | an octave from 1 to 12, a=number of octave (beginning from 0) |
||
2773 | Remarks: |
||
2774 | * Speaker play can be disabled/enabled by |
||
2775 | subfunction 8 of function 18. |
||
2776 | * Function returns control, having informed the system |
||
2777 | an information on request. Play itself goes independently from |
||
2778 | the program. |
||
2779 | * The data must be kept in the memory at least up to the end |
||
2780 | of play. |

||
2794 | * This function is obsolete; function 70 allows to fulfil the same |
||
2795 | operations with the extended possibilities. |
||
2796 | * This function assumes that during its call by one application |
||
2797 | no other application works with hard disk. |
||
2798 | * The path to file is ASCIIZ-string, which may be empty |
||
2799 | (if the file is created in the root folder) or have the format |
||
2800 | /d1/d2/.../dn, where all folder names must have the 8+3 format, |
||
2801 | i.e. 8 characters of name and 3 characters of the extension |
||
2802 | without separator, supplemented by blanks if necessary; |
||
2803 | all letters must be capital. |
||
2804 | * The file name must also have the format 8+3. |

2822 | * +20 = +0x14: n db: ASCIIZ-string with the file name |
||
2823 | Specifications - in documentation on the appropriate subfunction. |
||
2824 | Filename is case-insensitive for latin letters, russian letters |
||
2825 | must be capital. |
||
2826 | Format of filename: |
||
2827 | /base/number/dir1/dir2/.../dirn/file, |
||
2828 | where /base/number identifies device, on which file is located: |
||
2829 | one of |
||
2830 | * /RD/1 = /RAMDISK/1 to access ramdisk |
||
2831 | * /FD/1 = /FLOPPYDISK/1 to access first floppy drive, |
||
2832 | /FD/2 = /FLOPPYDISK/2 to access second one |
||
2833 | * /HD/x = /HARDDISK/x - obsolete variant of access to hard disk |
||
2834 | (in this case base is defined by subfunction 7 of function 21), |
||
2835 | x - partition number (beginning from 1) |
||
2836 | * /HD0/x, /HD1/x, /HD2/x, /HD3/x to access accordingly to devices |
||
2837 | IDE0 (Primary Master), IDE1 (Primary Slave), |
||
2838 | IDE2 (Secondary Master), IDE3 (Secondary Slave); |
||
2839 | x - partition number on the selected hard drive, varies from 1 |
||
2840 | to 255 (on each hard drive the indexing starts from 1) |
||
2841 | Remarks: |
||
2842 | * In the first two cases it is also possible to use FIRST |
||
2843 | instead of 1, SECOND instead of 2, but it is not recommended |
||
2844 | for convenience of transition to the future extensions. |
||
2845 | * Limitation n<=39 is imposed. |
||
2846 | * Names of folders and file dir1,...,dirn,file must have the |
||
2847 | format 8.3: name no more than 8 characters, dot, extension no |
||
2848 | more than 3 characters. Trailing spaces are ignored, no other |
||
2849 | spaces is allowed. If name occupies equally 8 characters, |
||
2850 | dot may be omitted (though it is not recommended to use this |
||
2851 | feature for convenience of transition to the future extensions). |
||
2852 | * This function does not support folders on ramdisk. |

2871 | ====================================================================== |
||
2872 | Parameters: |
||
2873 | * eax = 58 |
||
2874 | * ebx = pointer to the information structure |
||
2875 | Format of the information structure: |
||
2876 | * +0: dword: 0 = subfunction number |
||
2877 | * +4: dword: first block to read (beginning from 0) |
||
2878 | * +8: dword: amount of blocks to read |
||
2879 | * +12 = +0xC: dword: pointer to buffer for data |
||
2880 | * +16 = +0x10: dword: pointer to buffer for system operations |
||
2881 | (4096 bytes) |
||
2882 | * +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
||
2883 | given in the general description |
||
2884 | Returned value: |
||
2885 | * eax = 0 - success, otherwise file system error code |
||
2886 | * ebx = file size (in bytes) or -1=0xffffffff, if file was not found |
||
2887 | Remarks: |
||
2888 | * Block size is 512 bytes. |
||
2889 | * This function is obsolete, for reading files use subfunction 0 |
||
2890 | of function 70, for reading folders - subfunction 1 of |
||
2891 | function 70. |
||
2892 | * Function can read contents of a folder. Only FAT file system is |
||
2893 | supported. The format of FAT-folder is described |
||
2894 | in any FAT documentation. |
||
2895 | * Size of a folder is determined by size of FAT clusters chain. |
||
2896 | * If file was ended before last requested block was read, |
||
2897 | the function will read as many as it can, and after that return |
||
2898 | eax=6 (EOF). |
||
2899 | * Function can read root folders /rd/1,/fd/x,/hd[n]/x, but |
||
2900 | in the first two cases the current implementation does not follow |
||
2901 | to the declared rules: |
||
2902 | for /rd/1: |
||
2903 | * if one want to read 0 blocks, function considers, |
||
2904 | that he requested 1; |
||
2905 | * if one requests more than 14 blocks or starting block is |
||
2906 | not less than 14, function returns eax=5 (not found) и ebx=-1; |
||
2907 | * size of ramdisk root folder is 14 blocks, |
||
2908 | 0x1C00=7168 байт; but function returns ebx=0 |
||
2909 | (except of the case of previous item); |
||
2910 | * strangely enough, it is possible to read 14th block (which |
||
2911 | generally contains a garbage - I remind, the indexing begins |
||
2912 | from 0); |
||
2913 | * if some block with the number not less than 14 was requested, |
||
2914 | function returns eax=6(EOF); otherwise eax=0. |
||
2915 | For /fd/x: |
||
2916 | * if the start block is not less than 14, function returns |
||
2917 | eax=5 (not found) and ebx=0; |
||
2918 | * note that format of FAT12 allows floppies with the root size |
||
2919 | more or less than 14 blocks; |
||
2920 | * check for length is not performed; |
||
2921 | * if data was successful read, function returns |
||
2922 | eax=0,ebx=0; otherwise eax=10 (access denied), ebx=-1. |
||
2923 | * The function handles reading of special folders /,/rd,/fd,/hd[n]; |
||
2924 | but the result does not correspond to expected (on operations with |
||
2925 | normal files/folders), does not follow the declared rules, |
||
2926 | may be changed in future versions of the kernel and consequently |
||
2927 | is not described. To obtain the information about the equipment |
||
2928 | use subfunction 11 of function 18 or |
||
2929 | read corresponding folder with subfunction 1 of function 70. |

2957 | Parameters: |
||
2958 | * eax = 58 - function number |
||
2959 | * ebx = pointer to the information structure |
||
2960 | Format of the information structure: |

2970 | * eax = 0 - success, otherwise file system error code |
||
2971 | * ebx destroyed |
||
2972 | Remarks: |
||
2973 | * By operations with a floppy one should not delete not empty |
||
2974 | folder. The code working with hard disk deletes not empty folders |
||
2975 | correctly (i.e. recursively with all files and nested folders). |
||
2976 | Function 58 does not support folders on ramdisk. |

||
2981 | Parameters: |
||
2982 | * eax = 58 - function number |
||
2983 | * ebx = pointer to the information structure |
||
2984 | Format of the information structure: |
||
2985 | * +0: dword: 3 = subfunction number |

2990 | (4096 bytes) |
||
2991 | * +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
||
2992 | given in the general description |
||
2993 | Returned value: |
||
2994 | * eax = 0 - success, otherwise file system error code |
||
2995 | * ebx destroyed |
||
2996 | Remarks: |
||
2997 | * Ramdisk and floppies do not support this function, it is only |
||
2998 | for hard disks. |
||
2999 | * File must already exist (otherwise function returns 5, not found). |
||
3000 | To create files use subfunction 1. |
||
3001 | * If the starting position is greater than file size, the function |
||
3002 | returns eax=6(EOF). If the end position is greater than file size, |
||
3003 | file is extended. |
||
3004 | * The code of write processing for hard disk interpretes zero |
||
3005 | value of the field +8 as the instruction to truncate the file to |
||
3006 | the size, given in the field +4. However the code of processing |
||
3007 | 58th function blocks this possibility for applications by |
||
3008 | immediate return (with eax=0) in the case of zero size. |

3058 | from /hd/1, /hd/first, /harddisk/1, /harddisk/first or after this |
||
3059 | space or null character follows, function returns, strangely |

||
3077 | /rd/1 = /RamDisk/1, /hd/n = /HardDisk/n, |
||
3078 | 1<=n<=4 - number of device: 1=IDE0, ..., 4=IDE3. |
||
3079 | Instead of digits it is allowed, though not recommended for |

3080 | convenience of transition to future extensions, to use |
||
3081 | 'first','second','third','fourth'. |
||
3082 | Returned value: |
||
3083 | * for device name /hd/xxx, where xxx is not in the list above: |
||
3084 | * eax = ebx = 1 |
||
3085 | * for invalid device name (except for the previous case): |
||
3086 | * eax = 5 |
||
3087 | * ebx does not change |
||
3088 | * if LBA-access is disabled by subfunction 11 of function 21: |
||
3089 | * eax = 2 |
||
3090 | * ebx destroyed |
||
3091 | * for ramdisk: attempt to read block outside ramdisk |
||
3092 | (18*2*80 blocks) results in |
||
3093 | * eax = 3 |
||
3094 | * ebx = 0 |
||
3095 | * for successful read: |
||
3096 | * eax = ebx = 0 |
||
3097 | Remarks: |
||
3098 | * Block size is 512 bytes; function reads one block. |
||
3099 | * Do not depend on returned value, it can be changed |
||
3100 | in future versions. |
||
3101 | * Function requires that LBA-access to devices is enabled by |
||
3102 | subfunction 11 of function 21. To check this one can use |
||
3103 | subfunction 11 of function 26. |
||
3104 | * LBA-read of floppy is not supported. |
||
3105 | * Function reads data on physical hard drive; if for any reason |
||
3106 | data of the concrete partition are required, application must |
||
3107 | define starting sector of this partition (either directly |
||
3108 | through MBR, or from the full structure returned by |
||
3109 | подфункцией 11 функции 18). |
||
3110 | * Function does not check error code of hard disk, so request of |
||
3111 | nonexisting sector reads something (most probably it will be |
||
3112 | zeroes, but this is defined by device) and this is considered |
||
3113 | as success (eax=0). |

||
3127 | * +20 = +0x14: (only second character is checked) |
||
3128 | /rd=/RAMDISK or /hd=/HARDDISK |
||
3129 | Returned value: |
||
3130 | * if the second character does not belong to set {'r','R','h','H'}: |
||
3131 | * eax = 3 |
||
3132 | * ebx = ecx = dword [fileinfo] = 0 |
||
3133 | * for ramdisk: |
||
3134 | * eax = 0 (success) |
||
3135 | * ebx = total number of clusters = 2847 |
||
3136 | * ecx = number of free clusters |
||
3137 | * dword [fileinfo] = cluster size = 512 |
||
3138 | * for hard disk: base and partition are defined by subfunctions |
||
3139 | 7 and 8 of function 21: |
||
3140 | * eax = 0 (success) |
||
3141 | * ebx = total number of clusters |
||
3142 | * ecx = number of free clusters |
||
3143 | * dword [fileinfo] = cluster size (in bytes) |
||
3144 | Remarks: |
||
3145 | * Be not surprised to strange layout of 4th returned parameter |
||
3146 | - when this code was writing, at system calls application got |
||
3147 | only registers eax,ebx,ecx (from pushad-structure transmitted |
||
3148 | as argument to the system function). Now it is corrected, so, |
||
3149 | probably, it is meaningful to return cluster size in edx, while |
||
3150 | this function is not used yet. |
||
3151 | * There exists also subfunction 11 of function 18, |
||
3152 | which returns information on file system. From the full table |
||
3153 | of disk subsystem it is possible to deduce cluster size (there |
||
3154 | it is stored in sectors) and total number of clusters |
||
3155 | for hard disks. |

||
3169 | * +12 = +0xC: dword: ignored |

3170 | * +16 = +0x10: dword: pointer to buffer for system operations |
||
3171 | (4096 bytes) |
||
3172 | * +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
||
3173 | given in the general description |
||
3174 | Returned value: |
||
3175 | * eax > 0 - the program is loaded, eax contains PID |
||
3176 | * eax < 0 - an error has occured, -eax contains |
||
3177 | file system error code |
||
3178 | Remarks: |
||
3179 | * This function is obsolete, use subfunction 7 of function 70. |
||
3180 | * Command line must be terminated by character with code 0 |
||
3181 | (ASCIIZ-string); function takes into account either all characters |
||
3182 | up to terminating null inclusively or the first 256 charachters |
||
3183 | depending on what is less. |
||
3184 | * If the process is started as debugged, it is created in |
||
3185 | the suspended state; to run use subfunction 5 of function 69. |

3187 | ====================================================================== |
||
3188 | =============== Function 59 - trace last system calls. =============== |
||
3189 | ====================================================================== |
||
3190 | Gets data on all system calls of all processes. |
||
3191 | Parameters: |
||
3192 | * eax = 59 - function number |
||
3193 | * ebx = 0 - unique subfunction |
||
3194 | * ecx = pointer to the buffer |
||
3195 | * edx = size of the buffer |
||
3196 | Returned value: |
||
3197 | * eax = total number of system calls made from system boot |
||
3198 | (modulo 2^32) |
||
3199 | * ebx = 0 |
||
3200 | Format of information on one call: (size = 0x40 = 64 bytes) |
||
3201 | * +0: dword: PID of process/thread |
||
3202 | * +4: 7*dword: garbage |
||
3203 | * +32 = +0x20: dword: value of edi at the call |
||
3204 | * +36 = +0x24: dword: esi |
||
3205 | * +40 = +0x28: dword: ebp |
||
3206 | * +44 = +0x2C: dword: stack pointer of the kernel handler |
||
3207 | * +48 = +0x30: dword: ebx |
||
3208 | * +52 = +0x34: dword: edx |
||
3209 | * +56 = +0x38: dword: ecx |
||
3210 | * +60 = +0x3C: dword: eax (=number of system function) |
||
3211 | Remarks: |
||
3212 | * The function is used only in the application 'systrace'. |
||
3213 | It is rather difficult to imagine a situation, in which |
||
3214 | this application or this function are really useful; |
||
3215 | and all system calls for support of this function are a little |
||
3216 | decelerated (though not strongly)... |
||
3217 | * So there is a proposition to delete from the kernel |
||
3218 | support of this function, together with application 'systrace'. |
||
3219 | * The information on system calls saves in the system |
||
3220 | ring buffer with 0x10 entries. |
||
3221 | This function simply copies the given size of data |
||
3222 | from this buffer to the given address. |
||
3223 | * One can determine, which entry in the buffer corresponds to |
||
3224 | last system call, by value of eax, namely, it is the entry |
||
3225 | (eax and 0xF) (at offset (eax and 0xF)*0x40). |
||
3226 | * In the current implementation there can be the seldom |
||
3227 | meeting problems of unsynchronization, when the information |
||
3228 | on some calls becomes outdated. |
||
3229 | * Under the system buffer one page, 4Kb, is allocated. |
||
3230 | Size of an entry = 64 bytes. Why only 16 entries are used, |
||
3231 | is not clearly. |
||
3232 | * The value of esp at the moment of system call cannot |
||
3233 | be determined by this function. |
||
3234 | * The current implementation does not check edx for correctness. |

3236 | ====================================================================== |
||
3237 | ========== Function 60 - Inter Process Communication (IPC). ========== |
||
3238 | ====================================================================== |
||
3239 | IPC is used for message dispatching from one process/thread to |
||
3240 | another. Previously it is necessary to agree how to interpret |
||
3241 | the concrete message. |
||
3242 | |||
3243 | ----------- Subfunction 1 - set the area for IPC receiving ----------- |
||
3244 | Is called by process-receiver. |
||
3245 | Parameters: |
||
3246 | * eax = 60 - function number |
||
3247 | * ebx = 1 - subfunction number |
||
3248 | * ecx = pointer to the buffer |
||
3249 | * edx = size of the buffer |
||
3250 | Returned value: |
||
3251 | * eax = 0 - always success |
||
3252 | Format of IPC-buffer: |
||
3253 | * +0: dword: if nonzero, buffer is considered locked; |
||
3254 | lock/unlock the buffer, when you work with it and need that |
||
3255 | buffer data are not changed from outside (no new messages) |
||
3256 | * +4: dword: occupied place in the buffer (in bytes) |
||
3257 | * +8: first message |
||
3258 | * +8+n: second message |
||
3259 | * ... |
||
3260 | Format of a message: |
||
3261 | * +0: dword: PID of sender |
||
3262 | * +4: dword: message length (not including this header) |
||
3263 | * +8: n*byte: message data |
||
3264 | |||
3265 | ------------------ Subfunction 2 - send IPC message ------------------ |
||
3266 | Is called by process-sender. |
||
3267 | Parameters: |
||
3268 | * eax = 60 - function number |
||
3269 | * ebx = 2 - subfunction number |
||
3270 | * ecx = PID of receiver |
||
3271 | * edx = pointer to the message data |
||
3272 | * esi = message length (in bytes) |
||
3273 | Returned value: |
||
3274 | * eax = 0 - success |
||
3275 | * eax = 1 - the receiver has not defined buffer for IPC messages |
||
3276 | (can be, still have no time, |
||
3277 | and can be, this is not right process) |
||
3278 | * eax = 2 - the receiver has blocked IPC-buffer; try to wait a bit |
||
3279 | * eax = 3 - overflow of IPC-buffer of the receiver |
||
3280 | * eax = 4 - process/thread with such PID does not exist |
||
3281 | Remarks: |
||
3282 | * Immediately after writing of IPC-message to the buffer the system |
||
3283 | sends to the receiver the event with code 7 (see event codes). |
||
3284 | |||
3285 | ====================================================================== |
||
3286 | ==== Function 61 - get parameters for the direct graphics access. ==== |
||
3287 | ====================================================================== |
||
3288 | The data of the graphics screen (the memory area which displays |
||
3289 | screen contents) are accessible to a program directly, without |
||
3290 | any system calls, through the selector gs: |
||
3291 | mov eax, [gs:0] |
||
3292 | places in eax the first dword of the buffer, which contains |
||
3293 | information on color of the left upper point (and, possibly, colors |
||
3294 | of several following). |
||
3295 | mov [gs:0], eax |
||
3296 | by work in VESA modes with LFB sets color of the left upper point |
||
3297 | (and, possibly, colors of several following). |
||
3298 | To interpret the data of graphics screen program needs to know |
||
3299 | some parameters, returning by this function. |
||
3300 | Remarks: |
||
3301 | * Graphics parameters changes very seldom at work, |
||
3302 | namely, only in cases, when user works with the application VRR. |
||
3303 | * At videomode change the system redraws all windows (event |
||
3304 | with code 1) and redraws the background (event 5). |
||
3305 | Same events occur in other cases too, which meet much more often, |
||
3306 | than videomode change. |
||
3307 | * By operation in videomodes with LFB the selector gs points to |
||
3308 | LFB itself, so reading/writing on gs result directly in |
||
3309 | change of screen contents. By operation in videomodes without |
||
3310 | LFB gs points to some data area in the kernel, and all functions |
||
3311 | of screen output fulfil honesty double operation on writing |
||
3312 | directly to the screen and writing to this buffer. In result |
||
3313 | at reading contents of this buffer the results correspond to |
||
3314 | screen contents (with, generally speaking, large color |
||
3315 | resolution), and writing is ignored. |
||
3316 | One exception is the mode 320*200, for which main loop of the |
||
3317 | system thread updates the screen according to mouse movements. |
||
3318 | |||

||
3327 | it returns sizes on 1 pixel less. It is fully equivalent way. |

3453 | ====================================================================== |
||
3454 | ============== Function 63 - work with the debug board. ============== |
||
3455 | ====================================================================== |
||
3456 | The debug board is the global system buffer (with the size |
||
3457 | 512 bytes), to which any program can write (generally speaking, |
||
3458 | arbitrary) data and from which other program can read these data. |
||
3459 | By the agreement written data are text strings interpreted as |
||
3460 | debug messages on a course of program execution. The kernel in |
||
3461 | some situations also writes to the debug board information on |
||
3462 | execution of some functions; by the agreement kernel messages |
||
3463 | begins from the prefix "K : ". |
||
3464 | For view of the debug board the application 'board' was created, |
||
3465 | which reads data from the buffer and displays them in its window. |
||
3466 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
3467 | A character with null code in an end of line is not necessary, |
||
3468 | but also does not prevent. |
||
3469 | Because debugger has been written, the value of the debug board |
||
3470 | has decreased, as debugger allows to inspect completely a course of |
||
3471 | program execution without any efforts from the direction of program |
||
3472 | itself. Nevertheless in some cases the debug board is still useful. |
||
3473 | |||
3474 | ----------------------------- Write byte ----------------------------- |
||
3475 | Parameters: |
||
3476 | * eax = 63 - function number |
||
3477 | * ebx = 1 - subfunction number |
||
3478 | * cl = data byte |
||
3479 | Returned value: |
||
3480 | * function does not return value |
||
3481 | Remarks: |
||
3482 | * Byte is written to the buffer. Buffer size is 512 bytes. |
||
3483 | At buffer overflow all obtained data are lost. |
||
3484 | * For output to the debug board of more complicated objects |
||
3485 | (strings, numbers) it is enough to call this function in cycle. |
||
3486 | It is possible not to write the appropriate code manually and use |
||
3487 | file 'debug.inc', which is included into the distributive. |
||
3488 | |||
3489 | ----------------------------- Read byte ------------------------------ |
||
3490 | Takes away byte from the buffer. |
||
3491 | Parameters: |
||
3492 | * eax = 63 - function number |
||
3493 | * ebx = 2 - subfunction number |
||
3494 | Returned value: |
||
3495 | * eax = ebx = 0 - the buffer is empty |
||
3496 | * eax = byte, ebx = 1 - byte was successfully read |

||
3511 | |||
3512 | ====================================================================== |
||
3513 | ================== Function 66 - work with keyboard. ================= |
||
3514 | ====================================================================== |
||
3515 | The input mode influences results of reading keys by function 2. |
||
3516 | When a program loads, ASCII input mode is set for it. |
||
3517 | |||
3518 | -------------- Subfunction 1 - set keyboard input mode. -------------- |
||
3519 | Parameters: |
||
3520 | * eax = 66 - function number |
||
3521 | * ebx = 1 - subfunction number |
||
3522 | * ecx = mode: |
||
3523 | * 0 = normal (ASCII-characters) |
||
3524 | * 1 = scancodes |
||
3525 | Returned value: |
||
3526 | * function does not return value |
||
3527 | |||
3528 | -------------- Subfunction 2 - get keyboard input mode. -------------- |
||
3529 | Parameters: |
||
3530 | * eax = 66 - function number |
||
3531 | * ebx = 2 - subfunction number |
||
3532 | Returned value: |

3534 | |||
3535 | ------------ Subfunction 3 - get status of control keys. ------------- |
||
3536 | Parameters: |
||
3537 | * eax = 66 - function number |
||
3538 | * ebx = 3 - subfunction number |
||
3539 | Returned value: |
||
3540 | * eax = bit mask: |
||
3541 | * bit 0 (mask 1): left Shift is pressed |
||
3542 | * bit 1 (mask 2): right Shift is pressed |
||
3543 | * bit 2 (mask 4): left Ctrl is pressed |
||
3544 | * bit 3 (mask 8): right Ctrl is pressed |
||
3545 | * bit 4 (mask 0x10): left Alt is pressed |
||
3546 | * bit 5 (mask 0x20): right Alt is pressed |
||
3547 | * bit 6 (mask 0x40): CapsLock is on |
||
3548 | * bit 7 (mask 0x80): NumLock is on |
||
3549 | * bit 8 (mask 0x100): ScrollLock is on |
||
3550 | * other bits are cleared |
||
3551 | |||
3552 | -------------- Subfunction 4 - set system-wide hotkey. --------------- |
||
3553 | When hotkey is pressed, the system notifies only those applications, |
||
3554 | which have installed it; the active application (which receives |
||
3555 | all normal input) does not receive such keys. |
||
3556 | The notification consists in sending event with the code 2. |
||
3557 | Reading hotkey is the same as reading normal key - by function 2. |
||
3558 | Parameters: |
||
3559 | * eax = 66 - function number |
||
3560 | * ebx = 4 - subfunction number |
||
3561 | * cl determines key scancode; |
||
3562 | use cl=0 to give combinations such as Ctrl+Shift |
||
3563 | * edx = 0xXYZ determines possible states of control keys: |
||
3564 | * Z (low 4 bits) determines state of LShift and RShift: |
||
3565 | * 0 = no key must be pressed; |
||
3566 | * 1 = exactly one key must be pressed; |
||
3567 | * 2 = both keys must be pressed; |
||
3568 | * 3 = must be pressed LShift, but not RShift; |
||
3569 | * 4 = must be pressed RShift, but not LShift |
||
3570 | * Y - similar for LCtrl and RCtrl; |
||
3571 | * X - similar for LAlt and RAlt |
||
3572 | Returned value: |
||
3573 | * eax=0 - success |
||
3574 | * eax=1 - too mant hotkeys (maximum 256 are allowed) |
||
3575 | Remarks: |
||
3576 | * Hotkey can work either at pressing or at release. Release |
||
3577 | scancode of a key is more on 128 than pressing scancode |
||
3578 | (i.e. high bit is set). |
||
3579 | * Several applications can set the same combination; |
||
3580 | all such applications will be informed on pressing |
||
3581 | such combination. |
||
3582 | |||
3583 | -------------- Subfunction 5 - delete installed hotkey. -------------- |
||
3584 | Parameters: |
||
3585 | * eax = 66 - function number |
||
3586 | * ebx = 5 - subfunction number |
||
3587 | * cl = scancode of key and edx = 0xXYZ the same as in subfunction 4 |
||
3588 | Returned value: |
||
3589 | * eax = 0 - success |
||
3590 | * eax = 1 - there is no such hotkey |
||
3591 | Remarks: |
||
3592 | * When a process/thread terminates, all hotkey installed by it are |
||
3593 | deleted. |
||
3594 | * The call to this subfunction does not affect other applications. |
||
3595 | If other application has defined the same combination, it will |
||
3596 | still receive notices. |

||
3607 | Returned value: |
||
3608 | * function does not return value |
||
3609 | Remarks: |
||
3610 | * The value -1 for a parameter means "do not change"; e.g. to move |
||
3611 | the window without resizing it is possible to specify edx=esi=-1. |
||
3612 | * Previously the window must be defined by function 0. |
||
3613 | It sets initial coordinates and sizes of the window. |
||
3614 | * Sizes of the window are understood in sense of function 0, |
||
3615 | that is one pixel less than real sizes. |
||
3616 | * The function call for maximized windows is simply ignored. |
||
3617 | * For windows of appropriate styles position and/or sizes can be |
||
3618 | changed by user; current position and sizes can be obtained by |
||
3619 | call to function 9. |
||
3620 | * The function sends to the window redraw event (with the code 1). |
||

3801 | subfunction 0. |
||
3802 | Format of a message: |
||
3803 | * +0: dword: message code |
||
3804 | * +4: dword: PID of debugged process |

||
3813 | * 3 = debug exception int 1 = #DB |
||
3814 | * in addition dword-image of the register DR6 is given: |

3815 | * bits 0-3: condition of the corresponding breakpoint (set by |
||
3816 | subfunction 9) is satisfied |
||
3817 | * бит 14: exception has occured because of the trace mode |
||
3818 | (flag TF is set TF) |
||
3819 | * process is suspended |
||
3820 | When debugger terminates, all debugged processes are killed. |
||
3821 | If debugger does not want this, it must previously detach by |
||
3822 | subfunction 3. |
||
3823 | |||
3824 | All subfunctions are applicable only to processes/threads started |

||
4328 | Remarks: |
||
4329 | * Command line must be terminated by the character with the code 0 |
||
4330 | (ASCIIZ-string); function takes into account either all characters |
||
4331 | up to terminating zero inclusively or first 256 character |
||
4332 | regarding what is less. |
||
4333 | * If the process is started as debugged, it is created in |
||
4334 | the suspended state; to run use subfunction 5 of function 69. |

||
4337 | ========== Function 71, subfunction 1 - set window caption. ========== |
||
4338 | ====================================================================== |
||
4339 | Parameters: |
||
4340 | * eax = 71 - function number |
||
4341 | * ebx = 1 - subfunction number |
||
4342 | * ecx = pointer to caption string |
||
4343 | Returned value: |
||
4344 | * function does not return value |
||
4345 | Remarks: |
||
4346 | * String must be in the ASCIIZ-format. Disregarding real string |
||
4347 | length, no more than 255 characters are drawn. |
||
4348 | * Pass NULL in ecx to remove caption. |
||
4349 | |||
4350 | ====================================================================== |
||
4351 | =============== Function -1 - terminate thread/process =============== |
||
4352 | ====================================================================== |
||
4353 | Parameters: |
||
4354 | * eax = -1 - function number |
||
4355 | Returned value: |
||
4356 | * function does not return neither value nor control |
||
4357 | Remarks: |
||
4358 | * If the process did not create threads obviously, it has only |
||
4359 | one thread, which termination results in process termination. |
||
4360 | * If the current thread is last in the process, its termination |
||
4361 | also results in process terminates. |
||
4362 | * This function terminates the current thread. Other thread can be |
||
4363 | killed by call to subfunction 2 of function 18. |

4365 | ====================================================================== |
||
4366 | =========================== List of events =========================== |
||
4367 | ====================================================================== |
||
4368 | Next event can be retrieved by the call of one from functions 10 |
||
4369 | (to wait for event), 11 (to check without waiting), 23 |
||
4370 | (to wait during the given time). |
||
4371 | These functions return only those events, which enter into a mask set |
||
4372 | by function 40. By default it is first three, |
||
4373 | there is enough for most applications. |
||
4374 | Codes of events: |
||
4375 | * 1 = redraw event (is reset by call to function 0) |
||
4376 | * 2 = key on keyboard is pressed (acts, only when the window is |
||
4377 | active) or hotkey is pressed; is reset, when all keys from |
||
4378 | the buffer are read out by function 2 |
||
4379 | * 3 = button is pressed, defined earlier by function 8 |
||
4380 | (or close button, created implicitly by function 0; |
||
4381 | minimize button is handled by the system and sends no message; |
||
4382 | acts, only when the window is active; |
||
4383 | is reset when all buttons from the buffer |
||
4384 | are read out by function 17) |
||
4385 | * 4 = reserved (in current implementation never comes even after |
||
4386 | unmasking by function 40) |
||
4387 | * 5 = the desktop background is redrawed (is reset automatically |
||
4388 | after redraw, so if in redraw time program does not wait and |
||
4389 | does not check events, it will not remark this event) |
||
4390 | * 6 = mouse event (something happened - button pressing or moving; |
||
4391 | is reset at reading) |
||
4392 | * 7 = IPC event (see function 60 - |
||
4393 | Inter Process Communication; is reset at reading) |
||
4394 | * 8 = network event (is reset at reading) |
||
4395 | * 9 = debug event (is reset at reading; see |
||
4396 | debug subsystem) |
||
4397 | * 16..31 = event with appropriate IRQ |
||
4398 | (16=IRQ0, 31=IRQ15) (is reset after reading all IRQ data) |
||
4399 | |||
4400 | ====================================================================== |
||
4401 | =================== Error codes of the file system =================== |
||
4402 | ====================================================================== |
||
4403 | * 0 = success |
||
4404 | * 1 = base and/or partition of a hard disk is not defined |
||
4405 | (by subfunctions 7, 8 of function 21) |
||
4406 | * 2 = function is not supported for the given file system |
||
4407 | * 3 = unknown file system |
||
4408 | * 4 = is returned only from function 'rename' by transmission of |
||
4409 | the strongly incorrect parameter and in any way does not |
||
4410 | correspond to the description in the kernel sources |
||
4411 | "partition not defined at hd" |
||
4412 | * 5 = file not found |
||
4413 | * 6 = end of file, EOF |
||
4414 | * 7 = pointer lies outside of application memory |
||
4415 | * 8 = disk is full |
||
4416 | * 9 = FAT table is destroyed |
||
4417 | * 10 = access denied |
||
4418 | * 11 = device error |
||
4419 | Application start functions can return also following errors: |
||
4420 | * 30 = 0x1E = not enough memory |
||
4421 | * 31 = 0x1F = file is not executable |
||
4422 | * 32 = 0x20 = too many processes>>>=4>=n<=4>=39>0,>=ecx. |
