314 | diamond | 1 | SYSTEM FUNCTIONS of OS Kolibri 0.6.4.0 |
114 | mikedld | 2 | |
3 | Number of the function is located in the register eax. |
||
118 | diamond | 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. |
||

9 | ====================================================================== |
||
10 | ============== Function 0 - define and draw the window. ============== |
||
11 | ====================================================================== |
||
12 | Defines an application window. Draws a frame of the window, header and |
||
133 | diamond | 13 | working area. For skinned windows defines standard close and minimize |
14 | buttons. |
||
114 | mikedld | 15 | Parameters: |
118 | diamond | 16 | * eax = 0 - function number |
114 | mikedld | 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: |
||
131 | diamond | 21 | * Y=0 - type I - fixed-size window |
118 | diamond | 22 | * Y=1 - only define window area, draw nothing |
131 | diamond | 23 | * Y=2 - type II - variable-size window |
24 | * Y=3 - skinned window |
||
118 | diamond | 25 | * other possible values (from 4 up to 15) are reserved, |
114 | mikedld | 26 | function call with such Y is ignored |
118 | diamond | 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) |
||
114 | mikedld | 29 | * X = DCBA (bits) |
118 | diamond | 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 |
||
303 | mikedld | 35 | * C = 1 - don't fill working area on window draw |
118 | diamond | 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 |
||
114 | mikedld | 41 | * Y=0 - usual window, Y=1 - unmovable window |
118 | diamond | 42 | * X defines a gradient of header: X=0 - no gradient, |
114 | mikedld | 43 | X=8 - usual gradient, |
44 | for windows of a type II X=4 - negative gradient |
||
118 | diamond | 45 | * other values of X and Y are reserved |
46 | * edi = 0x00RRGGBB - color of the frame |
||
114 | mikedld | 47 | Returned value: |
48 | * function does not return value |
||
49 | Remarks: |
||
118 | diamond | 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, |
||
131 | diamond | 64 | and if it does not help too, the appropriate size |
118 | diamond | 65 | (or, probably, both) is installed in a size of the screen. |
114 | mikedld | 66 | |
131 | diamond | 67 | Further let us designate xpos,ypos,xsize,ysize - values passed |
68 | in ebx,ecx. The coordinates are resulted concerning |
||
118 | diamond | 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: |
||
114 | mikedld | 86 | * completely defined by the application |
118 | diamond | 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 |
||
114 | mikedld | 92 | * draw header - rectangle with the left upper corner (4,4) |
118 | diamond | 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 - |
||
114 | mikedld | 96 | rectangle with the left upper corner (5,20) and right lower |
118 | diamond | 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: |
||
114 | mikedld | 102 | * draw external frame of width 1 pixel |
118 | diamond | 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 |
||
114 | mikedld | 109 | (0,0) - (xsize,_skinh-1) |
118 | diamond | 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) |
||
133 | diamond | 114 | * define two standard buttons: close and minimize |
114 | mikedld | 115 | (see function 8) |
118 | diamond | 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 |
||
114 | mikedld | 120 | |
121 | ====================================================================== |
||
118 | diamond | 122 | ================ Function 1 - put pixel in the window. =============== |
114 | mikedld | 123 | ====================================================================== |
124 | Parameters: |
||
118 | diamond | 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) |
||
114 | mikedld | 131 | Returned value: |
132 | * function does not return value |
||
133 | |||
134 | ====================================================================== |
||
118 | diamond | 135 | ============ Function 2 - get the code of the pressed key. =========== |
114 | mikedld | 136 | ====================================================================== |
137 | Takes away the code of the pressed key from the buffer. |
||
138 | Parameters: |
||
118 | diamond | 139 | * eax = 2 - function number |
114 | mikedld | 140 | Returned value: |
118 | diamond | 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 |
||
114 | mikedld | 148 | Remarks: |
118 | diamond | 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. |
||

118 | diamond | 175 | * each item is BCD-number, for example, |
176 | for time 23:59:59 function returns 0x00595923 |
||
114 | mikedld | 177 | Remarks: |
118 | diamond | 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. |
||
114 | mikedld | 182 | |

||
118 | diamond | 187 | * eax = 4 - function number |
114 | mikedld | 188 | * ebx = [coordinate on axis x]*65536 + [coordinate on axis y] |
189 | * ecx = 0xX0RRGGBB, where |
||
118 | diamond | 190 | * RR, GG, BB specify text color |
139 | diamond | 191 | * X=ABnn (bits): |
185 | heavyiron | 192 | * nn specifies the used font: 0=system monospaced, |
193 | 1=system font of variable width |

139 | diamond | 194 | * A=0 - output esi characters, A=1 - output ASCIIZ-string |
195 | * B=1 - fill background with the color edi |
||
118 | diamond | 196 | * edx = pointer to the beginning of the string |
139 | diamond | 197 | * esi = for A=0 length of the string, must not exceed 255; |
198 | for A=1 is ignored |
||
114 | mikedld | 199 | Returned value: |
200 | * function does not return value |
||
201 | Remarks: |
||
118 | diamond | 202 | * First system font is read out at loading from the file char.mt, |
203 | second - from char2.mt. |
||
204 | * Both fonts have height 9 pixels, width of the monospaced font |
||
205 | is equal to 6 pixels. |

207 | ====================================================================== |
||
118 | diamond | 208 | ========================= Function 5 - delay. ======================== |
114 | mikedld | 209 | ====================================================================== |
210 | Delays execution of the program on the given time. |
||
211 | Parameters: |
||
118 | diamond | 212 | * eax = 5 - function number |
114 | mikedld | 213 | * ebx = time in the 1/100 of second |
214 | Returned value: |
||
215 | * function does not return value |
||
216 | Remarks: |
||
118 | diamond | 217 | * Passing ebx=0 does not transfer control to the next process |
218 | and does not make any operations at all. If it is really required |
||
219 | to transfer control to the next process (to complete a current |
||
220 | time slice), use subfunction 1 of function 68. |
||
221 | * At current implementation there will be an immediate return from |
||
222 | the function, if the addition of ebx with current value of |
||
223 | time counter will call 32-bit overflow. |
||
114 | mikedld | 224 | |
225 | ====================================================================== |

238 | * eax = -1, if the file was not found |
||
114 | mikedld | 239 | Remarks: |
118 | diamond | 240 | * This function is out-of-date; function 70 allows |
241 | to fulfil the same operations with the extended possibilities. |
||
114 | mikedld | 242 | * Block = 512 bytes. |
118 | diamond | 243 | * For reading all file you can specify the certainly large value |
244 | in edx, for example, edx = -1; but in this case be ready that |

||
246 | not be placed in the program memory. |
||
247 | * The filename must be either in the format 8+3 characters |

253 | The filename must be written with capital letters. The terminating |
||
254 | character with code 0 is not necessary (not ASCIIZ-string). |
||
255 | * This function does not support folders on the ramdisk. |

296 | for minimize of the window with identifier 0xffff. |
||
297 | * The creation of two buttons with same identifiers is admitted. |
||
298 | * The button with the identifier 0xffff at pressing is interpreted |
||
299 | by the system as the button of minimization, the system handles |
||
300 | such pressing independently, not accessing to the application. |
||
301 | In rest it is usual button. |
||
302 | * Total number of buttons for all applications is limited to 4095. |

114 | mikedld | 352 | Remarks: |
118 | diamond | 353 | * Slots are numbered starting from 1. |
354 | * Returned value is not a total number of threads, because there |
||
355 | can be free slots. |
||
356 | * When process is starting, system automatically creates |
||
357 | execution thread. |
||
358 | * Function gives information on the thread. Each process has |
||
359 | at least one thread. One process can create many threads, |
||
360 | in this case each thread has its own slot and the fields |
||
361 | +10, +22, +26 in these slots coincide. |
||
362 | Applications have no common way to define whether two threads |
||
114 | mikedld | 363 | belong to one process. |
118 | diamond | 364 | * The active window - window on top of the window stack - |
365 | receives the messages on a keyboard input. For such window |
||
366 | the position in the window stack coincides with returned value. |
||
367 | * Slot 1 corresponds to special system thread, for which: |
||
368 | * the window is in the bottom of the window stack, the fields |
||
369 | +4 and +6 contain value 1 |
||
370 | * name of the process - "OS/IDLE" (supplemented by spaces) |
||
371 | * address of the process in memory is 0, size of used memory is |
||
114 | mikedld | 372 | 16 Mb (0x1000000) |
373 | * PID=1 |
||
142 | diamond | 374 | * coordinates and sizes of the window and the client area are by |
375 | convention set to 0 |
||
118 | diamond | 376 | * status of the slot is always 0 (running) |
377 | * the execution time adds of time leaving on operations itself |
||
378 | and idle time in waiting for interrupt (which can be got by call |
||
379 | to subfunction 4 of function 18). |
||
380 | * Beginning from slot 2, the normal applications are placed. |
||
381 | * The normal applications are placed in memory at the address |
||
193 | diamond | 382 | 0x60400000 (kernel constant 'std_application_base_address'). |
118 | diamond | 383 | There is no intersection, as each process has its own page table. |
384 | * At creation of the thread it is assigned the slot |
||
385 | in the system table and identifier (Process/Thread IDentifier = |
||
386 | PID/TID), which do not vary with time for given thread. |
||
387 | After completion of the thread its slot can be anew used |
||
388 | for another thread. The thread identifier can not be assigned |
||
389 | to other thread even after completion of this thread. |
||
390 | Identifiers, assigned to new threads, grow monotonously. |
||
391 | * If the thread has not yet defined the window by call to |
||
392 | function 0, the position and the sizes |
||
393 | of its window are considered to be zero. |
||
142 | diamond | 394 | * Coordinates of the client area are relative to the window. |
118 | diamond | 395 | * At the moment only the part of the buffer by a size |
142 | diamond | 396 | 71 = 0x37 bytes is used. Nevertheless it is recommended to use |
118 | diamond | 397 | 1-Kb buffer for the future compatibility, in the future |
398 | some fields can be added. |

||
733 | * 4 = restart the kernel from the file 'kernel.mnt' on ramdisk |
||
114 | mikedld | 734 | Returned value: |
118 | diamond | 735 | * at incorrect ecx the registers do not change (i.e. eax=18) |
736 | * by correct call function always returns eax=0 |
||
737 | as the tag of success |
||
114 | mikedld | 738 | Remarks: |
118 | diamond | 739 | * Do not rely on returned value by incorrect call, it can be |
740 | changed in future versions of the kernel. |
||
741 | * It is possible to use subfunction 1, that on the last step |
||
742 | the user makes choice himself. |
||
743 | * It is not recommended to use value ecx=1 (to not irritate the user |
||
744 | with excessive questions); to save ramdisk on a floppy use |
||
745 | function 16 (which admits specification, on which floppy to |
||
746 | write), and to shutdown with the exit menu use already mentioned |
||
747 | subfunction 1. |

||
761 | * Restoring of an application window occurs at its activation by |
||
762 | subfunction 3. |
||
763 | * Usually there is no necessity to minimize/restire a window |
||
764 | obviously: minimization of a window is carried out by the system |
||
765 | at pressing the minimization button (for skinned windows |
||
766 | it is defined automatically by function 0, |
||
767 | for other windows it can be defined manually by function 8), |
||
768 | restore of a window is done by the application '@panel'. |

1340 | * Alarm clock can be set on operation in the given time every day. |
||
1341 | But there is no existing system function to disable it. |
||
1342 | * Operation of alarm clock consists in generation IRQ8. |
||
1343 | * Generally CMOS supports for alarm clock set of value 0xFF |

||
2211 | * (left,top) are coordinates of the left upper corner, |
||
2212 | (right,bottom) are coordinates of the right lower one. |
||
2213 | Thus the size of working area on x axis can be calculated by |
||
2214 | formula right-left+1, on y axis - by formula bottom-right+1. |
||
2215 | * If 'left'>='right', x-coordinate of working area is not changed. |
||
2216 | If 'left'<0, 'left' will not be set. If 'right' is greater than or |
||
2217 | equal to screen width, 'right' will not be set. |
||
2218 | Similarly on y axis. |

2311 | * function does not return value |
||
2312 | Remarks: |
||
118 | diamond | 2313 | * Default scale is 0 (scale factor is 1). If in the shape data |
2314 | one byte corresponds to one pixel, there is no necessity |
||
2315 | to set scale. |
||
2316 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2317 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2318 | functions 0, 67. |
118 | diamond | 2319 | * On definition of scale xsize and ysize must be divisible |
2320 | on 2^scale. |
||
2321 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2322 | to a window of square with the side 2^scale (if scale=0, |
||
2323 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2324 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2325 | * Data size: (xsize shr scale)*(ysize shr scale). |
2326 | * Data must be presented in the memory and not change |
||
2327 | after set of shape. |
||
2328 | * The system views the shape data at every window redraw by |
||
2329 | function 0. |
||
2330 | * The call of subfunction 0 with NULL pointer results in return |
||
2331 | to the rectangular shape. |

118 | diamond | 2897 | * ebx = pointer to the information structure |
2898 | Format of the information structure: |

2906 | given in the general description |
||
114 | mikedld | 2907 | Returned value: |
118 | diamond | 2908 | * eax = 0 - success, otherwise file system error code |
2909 | * ebx = file size (in bytes) or -1=0xffffffff, if file was not found |
||
114 | mikedld | 2910 | Remarks: |
118 | diamond | 2911 | * Block size is 512 bytes. |
114 | mikedld | 2912 | * This function is obsolete, for reading files use subfunction 0 |
118 | diamond | 2913 | of function 70, for reading folders - subfunction 1 of |
2914 | function 70. |
||
2915 | * Function can read contents of a folder. Only FAT file system is |
||
2916 | supported. The format of FAT-folder is described |
||
2917 | in any FAT documentation. |
||
2918 | * Size of a folder is determined by size of FAT clusters chain. |
||
2919 | * If file was ended before last requested block was read, |
||
2920 | the function will read as many as it can, and after that return |
||
2921 | eax=6 (EOF). |
||
2922 | * Function can read root folders /rd/1,/fd/x,/hd[n]/x, but |
||
2923 | in the first two cases the current implementation does not follow |
||
2924 | to the declared rules: |
||
114 | mikedld | 2925 | for /rd/1: |
118 | diamond | 2926 | * if one want to read 0 blocks, function considers, |
2927 | that he requested 1; |
||
2928 | * if one requests more than 14 blocks or starting block is |
||
2929 | not less than 14, function returns eax=5 (not found) и ebx=-1; |
||
2930 | * size of ramdisk root folder is 14 blocks, |
||
2931 | 0x1C00=7168 байт; but function returns ebx=0 |
||
2932 | (except of the case of previous item); |
||
2933 | * strangely enough, it is possible to read 14th block (which |
||
2934 | generally contains a garbage - I remind, the indexing begins |
||
2935 | from 0); |
||
2936 | * if some block with the number not less than 14 was requested, |
||
2937 | function returns eax=6(EOF); otherwise eax=0. |
||
2938 | For /fd/x: |
||
2939 | * if the start block is not less than 14, function returns |
||
2940 | eax=5 (not found) and ebx=0; |
||
2941 | * note that format of FAT12 allows floppies with the root size |
||
2942 | more or less than 14 blocks; |
||
2943 | * check for length is not performed; |
||
2944 | * if data was successful read, function returns |
||
2945 | eax=0,ebx=0; otherwise eax=10 (access denied), ebx=-1. |
||
2946 | * The function handles reading of special folders /,/rd,/fd,/hd[n]; |
||
2947 | but the result does not correspond to expected (on operations with |
||
2948 | normal files/folders), does not follow the declared rules, |
||
2949 | may be changed in future versions of the kernel and consequently |
||
2950 | is not described. To obtain the information about the equipment |
||
2951 | use subfunction 11 of function 18 or |

2952 | read corresponding folder with subfunction 1 of function 70. |

3014 | in future versions. |
||
3015 | * Function requires that LBA-access to devices is enabled by |

3049 | * ebx = total number of clusters = 2847 |
||
3050 | * ecx = number of free clusters |
||
3051 | * dword [fileinfo] = cluster size = 512 |
||
118 | diamond | 3052 | * for hard disk: base and partition are defined by subfunctions |
3053 | 7 and 8 of function 21: |

3058 | Remarks: |
||
118 | diamond | 3059 | * Be not surprised to strange layout of 4th returned parameter |
3060 | - when this code was writing, at system calls application got |
||
3061 | only registers eax,ebx,ecx (from pushad-structure transmitted |
||
3062 | as argument to the system function). Now it is corrected, so, |
||
3063 | probably, it is meaningful to return cluster size in edx, while |
||
3064 | this function is not used yet. |
||
3065 | * There exists also subfunction 11 of function 18, |
||
3066 | which returns information on file system. From the full table |
||
3067 | of disk subsystem it is possible to deduce cluster size (there |

118 | diamond | 3106 | * edx = pointer to the message data |
3107 | * esi = message length (in bytes) |
||
114 | mikedld | 3108 | Returned value: |
118 | diamond | 3109 | * eax = 0 - success |
3110 | * eax = 1 - the receiver has not defined buffer for IPC messages |
||
3111 | (can be, still have no time, |

114 | mikedld | 3122 | ====================================================================== |
118 | diamond | 3123 | The data of the graphics screen (the memory area which displays |
3124 | screen contents) are accessible to a program directly, without |
||
3125 | any system calls, through the selector gs: |
||
131 | diamond | 3126 | mov eax, [gs:0] |
118 | diamond | 3127 | places in eax the first dword of the buffer, which contains |
3128 | information on color of the left upper point (and, possibly, colors |
||
3129 | of several following). |
||
131 | diamond | 3130 | mov [gs:0], eax |
118 | diamond | 3131 | by work in VESA modes with LFB sets color of the left upper point |
3132 | (and, possibly, colors of several following). |
||
3133 | To interpret the data of graphics screen program needs to know |
||
3134 | some parameters, returning by this function. |
||
114 | mikedld | 3135 | Remarks: |
118 | diamond | 3136 | * Graphics parameters changes very seldom at work, |
3137 | namely, only in cases, when user works with the application VRR. |
||
3138 | * At videomode change the system redraws all windows (event |
||
3139 | with code 1) and redraws the background (event 5). |
||
3140 | Same events occur in other cases too, which meet much more often, |
||
3141 | than videomode change. |
||
3142 | * By operation in videomodes with LFB the selector gs points to |
||
3143 | LFB itself, so reading/writing on gs result directly in |
||
3144 | change of screen contents. By operation in videomodes without |
||
3145 | LFB gs points to some data area in the kernel, and all functions |
||
3146 | of screen output fulfil honesty double operation on writing |
||
3147 | directly to the screen and writing to this buffer. In result |
||
3148 | at reading contents of this buffer the results correspond to |
||
3149 | screen contents (with, generally speaking, large color |
||
3150 | resolution), and writing is ignored. |
||
3151 | One exception is the mode 320*200, for which main loop of the |
||
3152 | system thread updates the screen according to mouse movements. |

||
118 | diamond | 3289 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 3290 | ====================================================================== |
118 | diamond | 3291 | The debug board is the global system buffer (with the size |
3292 | 512 bytes), to which any program can write (generally speaking, |
||
3293 | arbitrary) data and from which other program can read these data. |
||
3294 | By the agreement written data are text strings interpreted as |
||
3295 | debug messages on a course of program execution. The kernel in |
||
3296 | some situations also writes to the debug board information on |
||
3297 | execution of some functions; by the agreement kernel messages |
||
3298 | begins from the prefix "K : ". |
||
3299 | For view of the debug board the application 'board' was created, |
||
3300 | which reads data from the buffer and displays them in its window. |
||
3301 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
3302 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 3303 | but also does not prevent. |
118 | diamond | 3304 | Because debugger has been written, the value of the debug board |
3305 | has decreased, as debugger allows to inspect completely a course of |
||
3306 | program execution without any efforts from the direction of program |
||
3307 | itself. Nevertheless in some cases the debug board is still useful. |
||
114 | mikedld | 3308 | |
118 | diamond | 3309 | ----------------------------- Write byte ----------------------------- |
114 | mikedld | 3310 | Parameters: |

3312 | * ebx = 1 - subfunction number |
||
3313 | * cl = data byte |
||
114 | mikedld | 3314 | Returned value: |
3315 | * function does not return value |
||
3316 | Remarks: |
||
118 | diamond | 3317 | * Byte is written to the buffer. Buffer size is 512 bytes. |
3318 | At buffer overflow all obtained data are lost. |
||
3319 | * For output to the debug board of more complicated objects |
||
3320 | (strings, numbers) it is enough to call this function in cycle. |
||
3321 | It is possible not to write the appropriate code manually and use |
||
3322 | file 'debug.inc', which is included into the distributive. |
||
114 | mikedld | 3323 | |
118 | diamond | 3324 | ----------------------------- Read byte ------------------------------ |
3325 | Takes away byte from the buffer. |
||
114 | mikedld | 3326 | Parameters: |

||
114 | mikedld | 3329 | Returned value: |
118 | diamond | 3330 | * eax = ebx = 0 - the buffer is empty |
3331 | * eax = byte, ebx = 1 - byte was successfully read |

114 | mikedld | 3340 | Returned value: |
118 | diamond | 3341 | * eax = 0 - success |
3342 | * eax = 1 - not enough memory |
||
114 | mikedld | 3343 | Remarks: |
193 | diamond | 3344 | * There is another way to dynamically allocate/free memory - |
3345 | subfunctions 11, 12, 13 of function 68. |
||
3346 | * The function cannot be used together with 68.11, 68.12, 68.13. |
||
3347 | The function call will be ignored after creation of process heap |
||
3348 | with function 68.11. |

||
3360 | ignored when esi = 24 and 32 |
||
3361 | * ebp = offset of next row data relative to previous row data |
||
283 | diamond | 3362 | Returned value: |
3363 | * function does not return value |
||
3364 | Remarks: |
||
3365 | * Coordinates of the image are coordinates of the upper left corner |
||
3366 | of the image relative to the window. |
||
3367 | * Size of the image in bytes is xsize*ysize. |
||
3368 | * Each byte of image is index in the palette. |
||
3369 | * If the image uses less than 256 colors, palette size may be |
||
3370 | less than 256 too. |
||
314 | diamond | 3371 | * The call to function 7 is equivalent to call to this function |
3372 | with esi=24, ebp=0. |

114 | mikedld | 3413 | |
118 | diamond | 3414 | -------------- Subfunction 4 - set system-wide hotkey. --------------- |
3415 | When hotkey is pressed, the system notifies only those applications, |
||
3416 | which have installed it; the active application (which receives |
||
3417 | all normal input) does not receive such keys. |
||
3418 | The notification consists in sending event with the code 2. |
||
3419 | Reading hotkey is the same as reading normal key - by function 2. |
||
114 | mikedld | 3420 | Parameters: |
118 | diamond | 3421 | * eax = 66 - function number |
3422 | * ebx = 4 - subfunction number |
||
3423 | * cl determines key scancode; |

||
3425 | * edx = 0xXYZ determines possible states of control keys: |
||
3426 | * Z (low 4 bits) determines state of LShift and RShift: |
||
3427 | * 0 = no key must be pressed; |
||
3428 | * 1 = exactly one key must be pressed; |
||
3429 | * 2 = both keys must be pressed; |
||
3430 | * 3 = must be pressed LShift, but not RShift; |
||
3431 | * 4 = must be pressed RShift, but not LShift |
||
3432 | * Y - similar for LCtrl and RCtrl; |

114 | mikedld | 3434 | Returned value: |
118 | diamond | 3435 | * eax=0 - success |
3436 | * eax=1 - too mant hotkeys (maximum 256 are allowed) |
||
114 | mikedld | 3437 | Remarks: |
118 | diamond | 3438 | * Hotkey can work either at pressing or at release. Release |
3439 | scancode of a key is more on 128 than pressing scancode |
||
3440 | (i.e. high bit is set). |
||
3441 | * Several applications can set the same combination; |
||
3442 | all such applications will be informed on pressing |

114 | mikedld | 3452 | * eax = 1 - there is no such hotkey |
3453 | Remarks: |
||
118 | diamond | 3454 | * When a process/thread terminates, all hotkey installed by it are |
3455 | deleted. |
||
3456 | * The call to this subfunction does not affect other applications. |
||
3457 | If other application has defined the same combination, it will |

||
3470 | * function does not return value |
||
3471 | Remarks: |
||
118 | diamond | 3472 | * The value -1 for a parameter means "do not change"; e.g. to move |
3473 | the window without resizing it is possible to specify edx=esi=-1. |
||
3474 | * Previously the window must be defined by function 0. |
||
114 | mikedld | 3475 | It sets initial coordinates and sizes of the window. |
118 | diamond | 3476 | * Sizes of the window are understood in sense of function 0, |
3477 | that is one pixel less than real sizes. |
||
3478 | * The function call for maximized windows is simply ignored. |
||
3479 | * For windows of appropriate styles position and/or sizes can be |
||
3480 | changed by user; current position and sizes can be obtained by |

118 | diamond | 3952 | * Process must be loaded for debugging (as is shown in |
3953 | general description). |
||
3954 | * Hardware breakpoints are implemented through DRx-registers of |
||
3955 | the processor, all limitations results from this. |
||
3956 | * The function can reinstall the breakpoint, previously set |
||
3957 | by it (and it does not inform on this). |
||
3958 | Carry on the list of set breakpoints in the debugger. |
||
3959 | * Breakpoints generate debug exception #DB, on which the system |
||
3960 | notifies debugger. |
||
3961 | * Breakpoints on write and read/write act after |
||
3962 | execution of the caused it instruction. |

4139 | and the parent folder. |
||
4140 | * The function allows also to read virtual folders "/", "/rd", |
||
4141 | "/fd", "/hd[n]", thus attributes of subfolders are set to 0x10, |

4408 | (to wait during the given time). |
||
4409 | These functions return only those events, which enter into a mask set |
||
4410 | by function 40. By default it is first three, |

114 | mikedld | 4412 | Codes of events: |
118 | diamond | 4413 | * 1 = redraw event (is reset by call to function 0) |
4414 | * 2 = key on keyboard is pressed (acts, only when the window is |
||
4415 | active) or hotkey is pressed; is reset, when all keys from |
||
4416 | the buffer are read out by function 2 |
||
4417 | * 3 = button is pressed, defined earlier by function 8 |
||
4418 | (or close button, created implicitly by function 0; |
||
4419 | minimize button is handled by the system and sends no message; |
||
4420 | acts, only when the window is active; |

4421 | is reset when all buttons from the buffer |
||
4422 | are read out by function 17) |

4423 | * 4 = reserved (in current implementation never comes even after |
||
4424 | unmasking by function 40) |
||
4425 | * 5 = the desktop background is redrawed (is reset automatically |
||
4426 | after redraw, so if in redraw time program does not wait and |
||
4427 | does not check events, it will not remark this event) |
||
4428 | * 6 = mouse event (something happened - button pressing or moving; |
||
4429 | is reset at reading) |
||
4430 | * 7 = IPC event (see function 60 - |
||
4431 | Inter Process Communication; is reset at reading) |
