1662 | Nasarus | 8 | SYSTEM FUNCTIONS of OS Kolibri 0.7.7.0 |
114 | mikedld | 9 | |
10 | Number of the function is located in the register eax. |
||
118 | diamond | 11 | The call of the system function is executed by "int 0x40" command. |
12 | All registers except explicitly declared in the returned value, |
||
13 | including eflags, are preserved. |
||

16 | ====================================================================== |
||
17 | ============== Function 0 - define and draw the window. ============== |
||
18 | ====================================================================== |
||
19 | Defines an application window. Draws a frame of the window, header and |
||
133 | diamond | 20 | working area. For skinned windows defines standard close and minimize |
21 | buttons. |
||
114 | mikedld | 22 | Parameters: |
118 | diamond | 23 | * eax = 0 - function number |
114 | mikedld | 24 | * ebx = [coordinate on axis x]*65536 + [size on axis x] |
25 | * ecx = [coordinate on axis y]*65536 + [size on axis y] |
||
26 | * edx = 0xXYRRGGBB, where: |
||
27 | * Y = style of the window: |
||
131 | diamond | 28 | * Y=0 - type I - fixed-size window |
118 | diamond | 29 | * Y=1 - only define window area, draw nothing |
131 | diamond | 30 | * Y=2 - type II - variable-size window |
31 | * Y=3 - skinned window |
||
641 | diamond | 32 | * Y=4 - skinned fixed-size window |
33 | * other possible values (from 5 up to 15) are reserved, |
||
114 | mikedld | 34 | function call with such Y is ignored |
118 | diamond | 35 | * RR, GG, BB = accordingly red, green, blue components of a color |
4051 | heavyiron | 36 | of the working area of the window (are ignored for style Y=1) |
114 | mikedld | 37 | * X = DCBA (bits) |
641 | diamond | 38 | * A = 1 - window has caption; for styles Y=3,4 caption string |
118 | diamond | 39 | must be passed in edi, for other styles use |
40 | subfunction 1 of function 71 |
||
41 | * B = 1 - coordinates of all graphics primitives are relative to |
||
42 | window client area |
||
303 | mikedld | 43 | * C = 1 - don't fill working area on window draw |
118 | diamond | 44 | * D = 0 - normal filling of the working area, 1 - gradient |
45 | The following parameters are intended for windows |
||
46 | of a type I and II, and ignored for styles Y=1,3: |
||
47 | * esi = 0xXYRRGGBB - color of the header |
||
48 | * RR, GG, BB define color |
||
4051 | heavyiron | 49 | * Y=0 - usual window, Y=1 - unmovable window (works for all window styles) |
118 | diamond | 50 | * X defines a gradient of header: X=0 - no gradient, |
114 | mikedld | 51 | X=8 - usual gradient, |
52 | for windows of a type II X=4 - negative gradient |
||
118 | diamond | 53 | * other values of X and Y are reserved |
54 | * edi = 0x00RRGGBB - color of the frame |
||
114 | mikedld | 55 | Returned value: |
56 | * function does not return value |
||
57 | Remarks: |
||
118 | diamond | 58 | * Position and sizes of the window are installed by the first |
59 | call of this function and are ignored at subsequent; to change |
||
60 | position and/or sizes of already created window use function 67. |
||
641 | diamond | 61 | * For windows with styles Y=3,4 and caption (A=1) caption string |
62 | is set by the first call of this function and is ignored |
||
63 | at subsequent (strictly speaking, is ignored after a call to |
||
64 | subfunction 2 of function 12 - end redraw); to change caption of |
||
65 | already created window use subfunction 1 of function 71. |
||
118 | diamond | 66 | * If the window has appropriate styles, position and/or sizes can be |
67 | changed by user. Current position and sizes can be obtained |
||
68 | by function 9. |
||
69 | * The window must fit on the screen. If the transferred |
||
70 | coordinates and sizes do not satisfy to this condition, |
||
71 | appropriate coordinate (or, probably, both) is considered as zero, |
||
131 | diamond | 72 | and if it does not help too, the appropriate size |
118 | diamond | 73 | (or, probably, both) is installed in a size of the screen. |
2409 | Serge | 74 | |
131 | diamond | 75 | Further let us designate xpos,ypos,xsize,ysize - values passed |
76 | in ebx,ecx. The coordinates are resulted concerning |
||
118 | diamond | 77 | the left upper corner of the window, which, thus, is set as (0,0), |
78 | coordinates of the right lower corner essence (xsize,ysize). |
||
79 | * The sizes of the window are understood in sence of coordinates |
||
80 | of the right lower corner. This concerns all other functions too. |
||
81 | It means, that the real sizes are on 1 pixel more. |
||
82 | * The window of type I looks as follows: |
||
83 | * draw external frame of color indicated in edi, 1 pixel in width |
||
84 | * draw header - rectangle with the left upper corner (1,1) and |
||
4572 | clevermous | 85 | right lower (xsize-1,min(20,ysize-1)) color indicated in esi |
118 | diamond | 86 | (taking a gradient into account) |
4572 | clevermous | 87 | * if ysize>21, fill the working area of the window - |
118 | diamond | 88 | rectangle with the left upper corner (1,21) and right lower |
89 | (xsize-1,ysize-1) (sizes (xsize-1)*(ysize-21)) with color |
||
90 | indicated in edx (taking a gradient into account) |
||
91 | * if A=1 and caption has been already set by subfunction 1 |
||
92 | of function 71, it is drawn in the corresponding place of header |
||
93 | * The window of style Y=1 looks as follows: |
||
114 | mikedld | 94 | * completely defined by the application |
118 | diamond | 95 | * The window of type II looks as follows: |
96 | * draw external frame of width 1 pixel with the "shaded" color |
||
97 | edi (all components of the color decrease twice) |
||
98 | * draw intermediate frame of width 3 pixels with color edi |
||
99 | * draw internal frame of width 1 pixel with the "shaded" color edi |
||
114 | mikedld | 100 | * draw header - rectangle with the left upper corner (4,4) |
118 | diamond | 101 | and right lower (xsize-4,min(20,ysize)) color, indicated in esi |
102 | (taking a gradient into account) |
||
103 | * if ysize>=26, fill the working area of the window - |
||
114 | mikedld | 104 | rectangle with the left upper corner (5,20) and right lower |
118 | diamond | 105 | (xsize-5,ysize-5) with color indicated in edx |
106 | (taking a gradient into account) |
||
107 | * if A=1 and caption has been already set by subfunction 1 |
||
108 | of function 71, it is drawn in the corresponding place of header |
||
109 | * The skinned window looks as follows: |
||
114 | mikedld | 110 | * draw external frame of width 1 pixel |
118 | diamond | 111 | with color 'outer' from the skin |
112 | * draw intermediate frame of width 3 pixel |
||
113 | with color 'frame' from the skin |
||
114 | * draw internal frame of width 1 pixel |
||
115 | with color 'inner' from the skin |
||
116 | * draw header (on bitmaps from the skin) in a rectangle |
||
114 | mikedld | 117 | (0,0) - (xsize,_skinh-1) |
118 | diamond | 118 | * if ysize>=26, fill the working area of the window - |
119 | rectangle with the left upper corner (5,_skinh) and right lower |
||
120 | (xsize-5,ysize-5) with color indicated in edx |
||
121 | (taking a gradient into account) |
||
133 | diamond | 122 | * define two standard buttons: close and minimize |
114 | mikedld | 123 | (see function 8) |
118 | diamond | 124 | * if A=1 and edi contains (nonzero) pointer to caption string, |
125 | it is drawn in place in header defined in the skin |
||
126 | * value _skinh is accessible as the result of call |
||
127 | subfunction 4 of function 48 |
||
114 | mikedld | 128 | |
129 | ====================================================================== |
||
118 | diamond | 130 | ================ Function 1 - put pixel in the window. =============== |
114 | mikedld | 131 | ====================================================================== |
132 | Parameters: |
||
118 | diamond | 133 | * eax = 1 - function number |
134 | * ebx = x-coordinate (relative to the window) |
||
135 | * ecx = y-coordinate (relative to the window) |
||
136 | * edx = 0x00RRGGBB - color of a pixel |
||
137 | edx = 0x01xxxxxx - invert color of a pixel |
||
138 | (low 24 bits are ignored) |
||
114 | mikedld | 139 | Returned value: |
140 | * function does not return value |
||
141 | |||
142 | ====================================================================== |
||
118 | diamond | 143 | ============ Function 2 - get the code of the pressed key. =========== |
114 | mikedld | 144 | ====================================================================== |
145 | Takes away the code of the pressed key from the buffer. |
||
146 | Parameters: |
||
118 | diamond | 147 | * eax = 2 - function number |
114 | mikedld | 148 | Returned value: |
118 | diamond | 149 | * if the buffer is empty, function returns eax=1 |
150 | * if the buffer is not empty, function returns al=0, |
||
4588 | mario79 | 151 | ah=code of the pressed key, |
4612 | mario79 | 152 | bits 16-23 = contain scancode for pressed key in ASCII mode, |
153 | in the scancodes mode this bits cleared. |
||
4588 | mario79 | 154 | bits 23-31 = zero |
118 | diamond | 155 | * if there is "hotkey", function returns al=2, |
156 | ah=scancode of the pressed key (0 for control keys), |
||
157 | high word of eax contains a status of control keys at the moment |
||
158 | of pressing a hotkey |
||
114 | mikedld | 159 | Remarks: |
118 | diamond | 160 | * There is a common system buffer of the pressed keys |
161 | by a size of 120 bytes, organized as queue. |
||
162 | * There is one more common system buffer on 120 "hotkeys". |
||
163 | * If the application with the inactive window calls this function, |
||
164 | the buffer of the pressed keys is considered to be empty. |
||
165 | * By default this function returns ASCII-codes; to switch |
||
166 | to the scancodes mode (and back) use function 66. |
||
167 | However, hotkeys are always notificated as scancodes. |
||
168 | * To find out, what keys correspond to what codes, start |
||
169 | the application keyascii and scancode. |
||
170 | * Scancodes come directly from keyboard and are fixed; |
||
171 | ASCII-codes turn out with usage of the conversion tables, |
||
172 | which can be set by subfunction 2 of function 21 |
||
173 | and get by subfunction 2 of function 26. |
||
174 | * As a consequence, ASCII-codes take into account current |
||
175 | keyboard layout (rus/en) as opposed to scancodes. |
||
176 | * This function notifies only about those hotkeys, which were |
||
177 | defined by this thread by subfunction 4 of function 66. |
||

||
118 | diamond | 183 | * eax = 3 - function number |
114 | mikedld | 184 | Returned value: |
185 | * eax = 0x00SSMMHH, where HH:MM:SS = Hours:Minutes:Seconds |
||
118 | diamond | 186 | * each item is BCD-number, for example, |
187 | for time 23:59:59 function returns 0x00595923 |
||
114 | mikedld | 188 | Remarks: |
118 | diamond | 189 | * See also subfunction 9 of function 26 - get time from |
190 | the moment of start of the system; it is more convenient, because |
||
191 | returns simply DWORD-value of the time counter. |
||
192 | * System time can be set by function 22. |
||
114 | mikedld | 193 | |

||
3780 | Serge | 209 | * nnn - not used in the current, must be 0 (zero) |
118 | diamond | 210 | * edx = pointer to the beginning of the string |
139 | diamond | 211 | * esi = for A=0 length of the string, must not exceed 255; |

||
3780 | Serge | 215 | |
114 | mikedld | 216 | Returned value: |
217 | * function does not return value |
||
218 | Remarks: |
||
118 | diamond | 219 | * First system font is read out at loading from the file char.mt, |
220 | second - from char2.mt. |
||
221 | * Both fonts have height 9 pixels, width of the monospaced font |
||
222 | is equal to 6 pixels. |
||
2536 | mario79 | 223 | * C=1, pixel depth = 32 bits, user area is as follows: |
224 | dword Xsize |
||
225 | dword Ysize |
||
226 | rest of the area = Xsize * Y size * 4 |
||
227 | * You can not use B = 1 and C = 1, at the same time. Since in both |
||
228 | cases, the register edi is used for different purposes. |

230 | ====================================================================== |
||
118 | diamond | 231 | ========================= Function 5 - delay. ======================== |
114 | mikedld | 232 | ====================================================================== |

237 | Returned value: |
||
238 | * function does not return value |
||
239 | Remarks: |
||
118 | diamond | 240 | * Passing ebx=0 does not transfer control to the next process |
241 | and does not make any operations at all. If it is really required |
||
242 | to transfer control to the next process (to complete a current |
||
243 | time slice), use subfunction 1 of function 68. |
||
114 | mikedld | 244 | |
245 | ====================================================================== |
||
118 | diamond | 246 | ============== Function 6 - read the file from ramdisk. ============== |

261 | to fulfil the same operations with the extended possibilities. |
||
114 | mikedld | 262 | * Block = 512 bytes. |
118 | diamond | 263 | * For reading all file you can specify the certainly large value |
264 | in edx, for example, edx = -1; but in this case be ready that |
||
265 | the program will "fall", if the file will appear too large and can |
||
266 | not be placed in the program memory. |
||
267 | * The filename must be either in the format 8+3 characters |
||
268 | (first 8 characters - name itself, last 3 - extension, |

270 | or in the format 8.3 characters "FILE.EXT"/"FILE.EX " |
||
271 | (name no more than 8 characters, dot, extension 3 characters |
||
272 | supplemented if necessary by spaces). |
||
273 | The filename must be written with capital letters. The terminating |
||
274 | character with code 0 is not necessary (not ASCIIZ-string). |
||
275 | * This function does not support folders on the ramdisk. |

118 | diamond | 312 | * Sizes of the button must be more than 0 and less than 0x8000. |
131 | diamond | 313 | * For skinned windows definition of the window |
118 | diamond | 314 | (call of 0th function) creates two standard buttons - |
315 | for close of the window with identifier 1 and |
||
316 | for minimize of the window with identifier 0xffff. |
||
317 | * The creation of two buttons with same identifiers is admitted. |
||
318 | * The button with the identifier 0xffff at pressing is interpreted |
||
319 | by the system as the button of minimization, the system handles |
||
320 | such pressing independently, not accessing to the application. |
||
321 | In rest it is usual button. |
||
322 | * Total number of buttons for all applications is limited to 4095. |

1662 | Nasarus | 403 | * The normal applications are placed in memory at the address |
404 | |||
118 | diamond | 405 | There is no intersection, as each process has its own page table. |
406 | * At creation of the thread it is assigned the slot |

407 | in the system table and identifier (Process/Thread IDentifier = |
||
408 | PID/TID), which do not vary with time for given thread. |
||
409 | After completion of the thread its slot can be anew used |
||
410 | for another thread. The thread identifier can not be assigned |
||
411 | to other thread even after completion of this thread. |
||
412 | Identifiers, assigned to new threads, grow monotonously. |

142 | diamond | 416 | * Coordinates of the client area are relative to the window. |
118 | diamond | 417 | * At the moment only the part of the buffer by a size |
4264 | 0CodErr | 418 | 76 = 0x4C bytes is used. Nevertheless it is recommended to use |
118 | diamond | 419 | 1-Kb buffer for the future compatibility, in the future |
420 | some fields can be added. |

||
1292 | * Alarm clock can be set on operation in the given time every day. |
||
1293 | But there is no existing system function to disable it. |
||
1294 | * Operation of alarm clock consists in generation IRQ8. |
||
1295 | * Generally CMOS supports for alarm clock set of value 0xFF |
||
1296 | as one of parameters and it means that the appropriate parameter |
||
1297 | is ignored. But current implementation does not allow this |
||
1298 | (will return 1). |
||
1299 | * Alarm clock is a global system resource; the set of |

118 | diamond | 1796 | * eax = 0 - success, thus ebx = entered byte |
1797 | * eax = 1 - the thread has not reserved the selected port |
||
114 | mikedld | 1798 | Remarks: |
118 | diamond | 1799 | * Previously the thread must reserve the selected port |
1800 | for itself by function 46. |

114 | mikedld | 1808 | ====================================================================== |
118 | diamond | 1809 | To work with reserved ports an application can access directly by |
1810 | commands in/out (recommended way) and can use function 43 |
||
1811 | (not recommended way). |
||
114 | mikedld | 1812 | Parameters: |
118 | diamond | 1813 | * eax = 46 - function number |
114 | mikedld | 1814 | * ebx = 0 - reserve, 1 - free |

114 | mikedld | 1819 | * eax = 1 - error |
1820 | Remarks: |
||
118 | diamond | 1821 | * For ports reservation: an error occurs if and only if |
1822 | one from the following condition satisfies: |
||
1823 | * start port is more than end port; |
||
1824 | * the selected range contains incorrect port number |
||
1825 | (correct are from 0 to 0xFFFF); |
||
1826 | * limit for the total number of reserved areas is exceeded |
||
1827 | (maximum 255 are allowed); |
||
1828 | * the selected range intersects with any of earlier reserved |
||
1829 | * For ports free: an error is an attempt to free range, |
||
1830 | that was not earlier reserved by this function |
||
1831 | (with same ecx,edx). |
||
1832 | * If an error occurs (for both cases) function performs no action. |
||
277 | diamond | 1833 | * At booting the system reserves for itself ports |
1834 | 0..0x2d, 0x30..0x4d, 0x50..0xdf, 0xe5..0xff (inclusively). |
||
118 | diamond | 1835 | * When a thread terminates, all reserved by it ports |
1836 | are freed automatically. |

2122 | * function does not return value |
||
2123 | Remarks: |
||
118 | diamond | 2124 | * Default scale is 0 (scale factor is 1). If in the shape data |
2125 | one byte corresponds to one pixel, there is no necessity |
||
2126 | to set scale. |
||
2127 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2128 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2129 | functions 0, 67. |
118 | diamond | 2130 | * On definition of scale xsize and ysize must be divisible |
2131 | on 2^scale. |
||
2132 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2133 | to a window of square with the side 2^scale (if scale=0, |
||
2134 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2135 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2136 | * Data size: (xsize shr scale)*(ysize shr scale). |
2137 | * Data must be presented in the memory and not change |
||
2138 | after set of shape. |
||
2139 | * The system views the shape data at every window redraw by |
||
2140 | function 0. |
||
2141 | * The call of subfunction 0 with NULL pointer results in return |
||
2142 | to the rectangular shape. |

114 | mikedld | 2274 | ====================================================================== |
118 | diamond | 2275 | IPC is used for message dispatching from one process/thread to |
2276 | another. Previously it is necessary to agree how to interpret |
||
114 | mikedld | 2277 | the concrete message. |
2278 | |||
118 | diamond | 2279 | ----------- Subfunction 1 - set the area for IPC receiving ----------- |

||
114 | mikedld | 2292 | * +4: dword: occupied place in the buffer (in bytes) |
2293 | * +8: first message |
||
2294 | * +8+n: second message |
||
2295 | * ... |
||
118 | diamond | 2296 | Format of a message: |
2297 | * +0: dword: PID of sender |

118 | diamond | 2307 | * edx = pointer to the message data |
2308 | * esi = message length (in bytes) |
||
114 | mikedld | 2309 | Returned value: |
118 | diamond | 2310 | * eax = 0 - success |
2311 | * eax = 1 - the receiver has not defined buffer for IPC messages |
||
2312 | (can be, still have no time, |
||
2313 | and can be, this is not right process) |
||
2314 | * eax = 2 - the receiver has blocked IPC-buffer; try to wait a bit |
||
2315 | * eax = 3 - overflow of IPC-buffer of the receiver |

118 | diamond | 2322 | ==== Function 61 - get parameters for the direct graphics access. ==== |
114 | mikedld | 2323 | ====================================================================== |
118 | diamond | 2324 | The data of the graphics screen (the memory area which displays |
2325 | screen contents) are accessible to a program directly, without |
||
2326 | any system calls, through the selector gs: |
||
1662 | Nasarus | 2327 | mov eax, [gs:0] |
118 | diamond | 2328 | places in eax the first dword of the buffer, which contains |
2329 | information on color of the left upper point (and, possibly, colors |
||
2330 | of several following). |
||
1662 | Nasarus | 2331 | mov [gs:0], eax |
118 | diamond | 2332 | by work in VESA modes with LFB sets color of the left upper point |
2333 | (and, possibly, colors of several following). |
||
2334 | To interpret the data of graphics screen program needs to know |
||
2335 | some parameters, returning by this function. |
||
114 | mikedld | 2336 | Remarks: |
118 | diamond | 2337 | * Graphics parameters changes very seldom at work, |
2338 | namely, only in cases, when user works with the application VRR. |
||
2339 | * At videomode change the system redraws all windows (event |
||
2340 | with code 1) and redraws the background (event 5). |
||
2341 | Same events occur in other cases too, which meet much more often, |
||
2342 | than videomode change. |
||
2343 | * By operation in videomodes with LFB the selector gs points to |
||
2344 | LFB itself, so reading/writing on gs result directly in |
||
2345 | change of screen contents. By operation in videomodes without |
||
2346 | LFB gs points to some data area in the kernel, and all functions |
||
2347 | of screen output fulfil honesty double operation on writing |
||
2348 | directly to the screen and writing to this buffer. In result |
||
2349 | at reading contents of this buffer the results correspond to |
||
2350 | screen contents (with, generally speaking, large color |
||
2351 | resolution), and writing is ignored. |
||
2352 | One exception is the mode 320*200, for which main loop of the |
||
2353 | system thread updates the screen according to mouse movements. |

118 | diamond | 2490 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 2491 | ====================================================================== |
118 | diamond | 2492 | The debug board is the global system buffer (with the size |
499 | diamond | 2493 | 1024 bytes), to which any program can write (generally speaking, |
118 | diamond | 2494 | arbitrary) data and from which other program can read these data. |
2495 | By the agreement written data are text strings interpreted as |
||
2496 | debug messages on a course of program execution. The kernel in |
||
2497 | some situations also writes to the debug board information on |
||
2498 | execution of some functions; by the agreement kernel messages |
||
2499 | begins from the prefix "K : ". |
||
2500 | For view of the debug board the application 'board' was created, |
||
2501 | which reads data from the buffer and displays them in its window. |
||
2502 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
2503 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 2504 | but also does not prevent. |
118 | diamond | 2505 | Because debugger has been written, the value of the debug board |

||
2649 | * Z (low 4 bits) determines state of LShift and RShift: |
||
2650 | * 0 = no key must be pressed; |
||
2651 | * 1 = exactly one key must be pressed; |
||
2652 | * 2 = both keys must be pressed; |
||
2653 | * 3 = must be pressed LShift, but not RShift; |

||
114 | mikedld | 2660 | Remarks: |
118 | diamond | 2661 | * Hotkey can work either at pressing or at release. Release |
2662 | scancode of a key is more on 128 than pressing scancode |
||
2663 | (i.e. high bit is set). |
||
2664 | * Several applications can set the same combination; |
||
2665 | all such applications will be informed on pressing |

118 | diamond | 2677 | * When a process/thread terminates, all hotkey installed by it are |
2678 | deleted. |
||
2679 | * The call to this subfunction does not affect other applications. |

||
2717 | * Previously the window must be defined by function 0. |
||
114 | mikedld | 2718 | It sets initial coordinates and sizes of the window. |
118 | diamond | 2719 | * Sizes of the window are understood in sense of function 0, |
2720 | that is one pixel less than real sizes. |
||
2721 | * The function call for maximized windows is simply ignored. |
||
2722 | * For windows of appropriate styles position and/or sizes can be |
||
2723 | changed by user; current position and sizes can be obtained by |

3026 | ====================================================================== |
||
3027 | ======== Function 68, subfunction 24 - set exception handler. ======== |
||
3028 | ====================================================================== |
||
3029 | Parameters: |
||
3030 | * eax = 68 - function number |
||
1077 | Galkov | 3031 | * ebx = 24 - subfunction number |
3032 | * ecx = address of the new exception handler |
||
1662 | Nasarus | 3033 | * edx = the mask of handled exceptions |
1077 | Galkov | 3034 | Returned value: |
3035 | * eax = address of the old exception handler (0, if it was not set) |
||
1662 | Nasarus | 3036 | * ebx = the old mask of handled exceptions |
1077 | Galkov | 3037 | Remarks: |
1662 | Nasarus | 3038 | * Bit number in mask of exceptions corresponds to exception number |
3039 | in CPU-specification (Intel-PC). For example, FPU exceptions have |
||
3040 | number 16 (#MF), and SSE exceptions - 19 (#XF). |
||
3041 | * The current implementation ignores the inquiry for hook of 7 |
||
3042 | exception - the system handles #NM by its own. |
||
3043 | * The exception handler is called with exception number as first |
||
3044 | (and only) stack parameter. So, correct exit from the handler is |
||
3045 | RET 4. It returns to the instruction, that caused the exception, |
||
3046 | for faults, and to the next instruction for traps (see |
||
3047 | classification of exceptions in CPU specification). |
||
3048 | * When user handler receives control, the corresponding bit in |
||
3049 | the exception mask is cleared. Raising this exception |
||
3050 | in consequence leads to default handling, that is, |
||
3051 | terminating the application in absence of debugger or |
||
3052 | suspend with notification of debugger otherwise. |
||
3053 | * After user handler completes critical operations, it can set |
||
3054 | the corresponding bit in the exception mask with subfunction 25. |
||
3055 | Also user handler is responsible for clearing exceptions flags in |
||
3056 | FPU and/or SSE. |

4045 | Parameters: |
||
118 | diamond | 4046 | * eax = -1 - function number |
114 | mikedld | 4047 | Returned value: |
118 | diamond | 4048 | * function does not return neither value nor control |
114 | mikedld | 4049 | Remarks: |
118 | diamond | 4050 | * If the process did not create threads obviously, it has only |
4051 | one thread, which termination results in process termination. |
||
4052 | * If the current thread is last in the process, its termination |
||
4053 | also results in process terminates. |
||
4054 | * This function terminates the current thread. Other thread can be |
||
4055 | killed by call to subfunction 2 of function 18. |

4058 | =========================== List of events =========================== |
||
4059 | ====================================================================== |
||
118 | diamond | 4060 | Next event can be retrieved by the call of one from functions 10 |
4061 | (to wait for event), 11 (to check without waiting), 23 |
||
4062 | (to wait during the given time). |
||
4063 | These functions return only those events, which enter into a mask set |
||
4064 | by function 40. By default it is first three, |
||
4065 | there is enough for most applications. |
||
114 | mikedld | 4066 | Codes of events: |
118 | diamond | 4067 | * 1 = redraw event (is reset by call to function 0) |
4068 | * 2 = key on keyboard is pressed (acts, only when the window is |
||
4069 | active) or hotkey is pressed; is reset, when all keys from |
||
4070 | the buffer are read out by function 2 |
||
4071 | * 3 = button is pressed, defined earlier by function 8 |
||
4072 | (or close button, created implicitly by function 0; |
||
4073 | minimize button is handled by the system and sends no message; |
||
4074 | acts, only when the window is active; |
||
4075 | is reset when all buttons from the buffer |
||
4076 | are read out by function 17) |
||
4077 | * 4 = reserved (in current implementation never comes even after |
||
4078 | unmasking by function 40) |
||
2513 | mario79 | 4079 | * 5 = kernel finished redrawing of the desktop background |
118 | diamond | 4080 | * 6 = mouse event (something happened - button pressing or moving; |
4081 | is reset at reading) |
||
4082 | * 7 = IPC event (see function 60 - |
||
4083 | Inter Process Communication; is reset at reading) |
||
4084 | * 8 = network event (is reset at reading) |
||
4085 | * 9 = debug event (is reset at reading; see |
||
4086 | debug subsystem) |
||
4087 | * 16..31 = event with appropriate IRQ |
||
4088 | (16=IRQ0, 31=IRQ15) (is reset after reading all IRQ data) |

4096 | * 2 = function is not supported for the given file system |
||
4097 | * 3 = unknown file system |
||
448 | diamond | 4098 | * 4 = reserved, is never returned in the current implementation |
118 | diamond | 4099 | * 5 = file not found |
4100 | * 6 = end of file, EOF |

4103 | * 9 = FAT table is destroyed |
||
114 | mikedld | 4104 | * 10 = access denied |
118 | diamond | 4105 | * 11 = device error |
4106 | Application start functions can return also following errors: |
