114 | mikedld | 1 | SYSTEM FUNCTIONS of OS Kolibri 0.5.8.1 |
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 |
||
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 |
||
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 |
||

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. |
||

114 | mikedld | 173 | Returned value: |
174 | * eax = 0x00SSMMHH, where HH:MM:SS = Hours:Minutes:Seconds |
||
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 | |
183 | ====================================================================== |
||

114 | mikedld | 185 | ====================================================================== |
186 | Parameters: |
||
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 |
191 | * X specifies the used font: 0=system monospaced, |

114 | mikedld | 195 | Returned value: |
196 | * function does not return value |
||
197 | Remarks: |
||
118 | diamond | 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. |

114 | mikedld | 205 | |
206 | ====================================================================== |
||
118 | diamond | 207 | ========================= Function 5 - delay. ======================== |
114 | mikedld | 208 | ====================================================================== |
209 | Delays execution of the program on the given time. |
||
210 | Parameters: |
||
118 | diamond | 211 | * eax = 5 - function number |
114 | mikedld | 212 | * ebx = time in the 1/100 of second |
213 | Returned value: |
||
214 | * function does not return value |
||
215 | Remarks: |
||
118 | diamond | 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. |
||
114 | mikedld | 223 | |
224 | ====================================================================== |

240 | to fulfil the same operations with the extended possibilities. |
||
114 | mikedld | 241 | * Block = 512 bytes. |
118 | diamond | 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 |

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. |
||

277 | * ecx = [coordinate on axis y]*65536 + [size on axis y] |
||
278 | * edx = 0xXYnnnnnn, where: |
||
279 | * nnnnnn = identifier of the button |

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. |

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 |
||
114 | mikedld | 353 | belong to one process. |
118 | diamond | 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 |
||
114 | mikedld | 362 | 16 Mb (0x1000000) |
363 | * PID=1 |
||
118 | diamond | 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 |
||
374 | in the system table and identifier (Process/Thread IDentifier = |
||
375 | PID/TID), which do not vary with time for given thread. |
||
376 | After completion of the thread its slot can be anew used |
||
377 | for another thread. The thread identifier can not be assigned |
||
378 | to other thread even after completion of this thread. |
||
379 | Identifiers, assigned to new threads, grow monotonously. |
||
380 | * If the thread has not yet defined the window by call to |
||
381 | function 0, the position and the sizes |
||
382 | of its window are considered to be zero. |
||
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. |

721 | * ebx = 9 - subfunction number |
||
114 | mikedld | 722 | * ecx = parameter: |
118 | diamond | 723 | * 1 = on the last step of shutdown save ramdisk on a floppy and |
724 | then show the exit menu and request further operations |
||
725 | from the user |
||
726 | * 2 = turn off computer |
||
727 | * 3 = reboot computer |
||
728 | * 4 = restart the kernel from the file 'kernel.mnt' on ramdisk |
||
114 | mikedld | 729 | Returned value: |
118 | diamond | 730 | * at incorrect ecx the registers do not change (i.e. eax=18) |
731 | * by correct call function always returns eax=0 |
||
732 | as the tag of success |
||
114 | mikedld | 733 | Remarks: |
118 | diamond | 734 | * Do not rely on returned value by incorrect call, it can be |
735 | changed in future versions of the kernel. |
||
736 | * It is possible to use subfunction 1, that on the last step |
||
737 | the user makes choice himself. |
||
738 | * It is not recommended to use value ecx=1 (to not irritate the user |
||
739 | with excessive questions); to save ramdisk on a floppy use |
||
740 | function 16 (which admits specification, on which floppy to |
||
741 | write), and to shutdown with the exit menu use already mentioned |
||
742 | subfunction 1. |

||
114 | mikedld | 748 | Parameters: |
118 | diamond | 749 | * eax = 18 - function number |
750 | * ebx = 10 - subfunction number |
||
114 | mikedld | 751 | Returned value: |
752 | * function does not return value |
||
753 | Remarks: |
||
118 | diamond | 754 | * The minimized window from the point of view of function 9 |
755 | keeps position and sizes. |
||
756 | * Restoring of an application window occurs at its activation by |
||
757 | subfunction 3. |
||
758 | * Usually there is no necessity to minimize/restire a window |
||
759 | obviously: minimization of a window is carried out by the system |
||
760 | at pressing the minimization button (for skinned windows |
||
761 | it is defined automatically by function 0, |
||
762 | for other windows it can be defined manually by function 8), |
||
763 | restore of a window is done by the application '@panel'. |

977 | code, so set it carefully, at incorrect value the cursor |
||
978 | can "freeze". Speed of the mouse can be regulated through the |
||
979 | application SETUP. |
||
980 | * Recommended delay of the mouse (in subsubfunction 3) = 10. Lower |
||
981 | value is not handled by COM mice. At the very large values the |
||
982 | movement of the mouse on 1 pixel is impossible and the cursor will |

1369 | But there is no existing system function to disable it. |
||
1370 | * Operation of alarm clock consists in generation IRQ8. |
||
1371 | * Generally CMOS supports for alarm clock set of value 0xFF |

||
2220 | * (left,top) are coordinates of the left upper corner, |
||
2221 | (right,bottom) are coordinates of the right lower one. |
||
2222 | Thus the size of working area on x axis can be calculated by |
||
2223 | formula right-left+1, on y axis - by formula bottom-right+1. |
||
2224 | * If 'left'>='right', x-coordinate of working area is not changed. |
||
2225 | If 'left'<0, 'left' will not be set. If 'right' is greater than or |
||
2226 | equal to screen width, 'right' will not be set. |
||
2227 | Similarly on y axis. |

114 | mikedld | 2319 | Returned value: |
2320 | * function does not return value |
||
2321 | Remarks: |
||
118 | diamond | 2322 | * Default scale is 0 (scale factor is 1). If in the shape data |
2323 | one byte corresponds to one pixel, there is no necessity |
||
2324 | to set scale. |
||
2325 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2326 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2327 | functions 0, 67. |
118 | diamond | 2328 | * On definition of scale xsize and ysize must be divisible |
2329 | on 2^scale. |
||
2330 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2331 | to a window of square with the side 2^scale (if scale=0, |
||
2332 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2333 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2334 | * Data size: (xsize shr scale)*(ysize shr scale). |
2335 | * Data must be presented in the memory and not change |
||
2336 | after set of shape. |
||
2337 | * The system views the shape data at every window redraw by |
||
2338 | function 0. |
||
2339 | * The call of subfunction 0 with NULL pointer results in return |
||
2340 | to the rectangular shape. |

114 | mikedld | 2858 | Remarks: |
118 | diamond | 2859 | * In the first two cases it is also possible to use FIRST |
2860 | instead of 1, SECOND instead of 2, but it is not recommended |
||
2861 | for convenience of transition to the future extensions. |
||
2862 | * Limitation n<=39 is imposed. |

2863 | * Names of folders and file dir1,...,dirn,file must have the |
||
2864 | format 8.3: name no more than 8 characters, dot, extension no |
||
2865 | more than 3 characters. Trailing spaces are ignored, no other |
||
2866 | spaces is allowed. If name occupies equally 8 characters, |

2891 | Format of the information structure: |

2893 | * +4: dword: first block to read (beginning from 0) |

||
2895 | * +12 = +0xC: dword: pointer to buffer for data |

118 | diamond | 2898 | * +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
2899 | given in the general description |
||
114 | mikedld | 2900 | Returned value: |
118 | diamond | 2901 | * eax = 0 - success, otherwise file system error code |
2902 | * ebx = file size (in bytes) or -1=0xffffffff, if file was not found |
||
114 | mikedld | 2903 | Remarks: |
118 | diamond | 2904 | * Block size is 512 bytes. |
114 | mikedld | 2905 | * This function is obsolete, for reading files use subfunction 0 |
118 | diamond | 2906 | of function 70, for reading folders - subfunction 1 of |
2907 | function 70. |
||
2908 | * Function can read contents of a folder. Only FAT file system is |
||
2909 | supported. The format of FAT-folder is described |
||
2910 | in any FAT documentation. |
||
2911 | * Size of a folder is determined by size of FAT clusters chain. |
||
2912 | * If file was ended before last requested block was read, |
||
2913 | the function will read as many as it can, and after that return |
||
2914 | eax=6 (EOF). |
||
2915 | * Function can read root folders /rd/1,/fd/x,/hd[n]/x, but |
||
2916 | in the first two cases the current implementation does not follow |
||
2917 | to the declared rules: |
||
114 | mikedld | 2918 | for /rd/1: |
118 | diamond | 2919 | * if one want to read 0 blocks, function considers, |
2920 | that he requested 1; |
||
2921 | * if one requests more than 14 blocks or starting block is |
||
2922 | not less than 14, function returns eax=5 (not found) и ebx=-1; |
||
2923 | * size of ramdisk root folder is 14 blocks, |
||
2924 | 0x1C00=7168 байт; but function returns ebx=0 |
||
2925 | (except of the case of previous item); |
||
2926 | * strangely enough, it is possible to read 14th block (which |
||
2927 | generally contains a garbage - I remind, the indexing begins |
||
2928 | from 0); |
||
2929 | * if some block with the number not less than 14 was requested, |
||
2930 | function returns eax=6(EOF); otherwise eax=0. |
||
2931 | For /fd/x: |
||
2932 | * if the start block is not less than 14, function returns |
||
2933 | eax=5 (not found) and ebx=0; |
||
2934 | * note that format of FAT12 allows floppies with the root size |
||
2935 | more or less than 14 blocks; |
||
2936 | * check for length is not performed; |
||
2937 | * if data was successful read, function returns |
||
2938 | eax=0,ebx=0; otherwise eax=10 (access denied), ebx=-1. |
||
2939 | * The function handles reading of special folders /,/rd,/fd,/hd[n]; |
||
2940 | but the result does not correspond to expected (on operations with |
||
2941 | normal files/folders), does not follow the declared rules, |
||
2942 | may be changed in future versions of the kernel and consequently |
||
2943 | is not described. To obtain the information about the equipment |
||
2944 | use subfunction 11 of function 18 or |
||
2945 | read corresponding folder with subfunction 1 of function 70. |

114 | mikedld | 3195 | Remarks: |
118 | diamond | 3196 | * The function is used only in the application 'systrace'. |
3197 | It is rather difficult to imagine a situation, in which |
||
3198 | this application or this function are really useful; |
||
3199 | and all system calls for support of this function are a little |
||
3200 | decelerated (though not strongly)... |
||
3201 | * So there is a proposition to delete from the kernel |
||
3202 | support of this function, together with application 'systrace'. |
||
3203 | * The information on system calls saves in the system |
||
3204 | ring buffer with 0x10 entries. |
||
3205 | This function simply copies the given size of data |
||
3206 | from this buffer to the given address. |
||
3207 | * One can determine, which entry in the buffer corresponds to |
||
3208 | last system call, by value of eax, namely, it is the entry |
||
3209 | (eax and 0xF) (at offset (eax and 0xF)*0x40). |
||
3210 | * In the current implementation there can be the seldom |
||
3211 | meeting problems of unsynchronization, when the information |
||
3212 | on some calls becomes outdated. |
||
3213 | * Under the system buffer one page, 4Kb, is allocated. |
||
3214 | Size of an entry = 64 bytes. Why only 16 entries are used, |
||
3215 | is not clearly. |
||
3216 | * The value of esp at the moment of system call cannot |
||
3217 | be determined by this function. |
||
3218 | * The current implementation does not check edx for correctness. |

114 | mikedld | 3222 | ====================================================================== |
118 | diamond | 3223 | IPC is used for message dispatching from one process/thread to |
3224 | another. Previously it is necessary to agree how to interpret |
||
114 | mikedld | 3225 | the concrete message. |
3226 | |||
118 | diamond | 3227 | ----------- Subfunction 1 - set the area for IPC receiving ----------- |
3228 | Is called by process-receiver. |
||
114 | mikedld | 3229 | Parameters: |
118 | diamond | 3230 | * eax = 60 - function number |
3231 | * ebx = 1 - subfunction number |
||
3232 | * ecx = pointer to the buffer |
||
3233 | * edx = size of the buffer |

114 | mikedld | 3251 | Parameters: |
118 | diamond | 3252 | * eax = 60 - function number |
3253 | * ebx = 2 - subfunction number |
||
114 | mikedld | 3254 | * ecx = PID of receiver |
118 | diamond | 3255 | * edx = pointer to the message data |
3256 | * esi = message length (in bytes) |
||
114 | mikedld | 3257 | Returned value: |
118 | diamond | 3258 | * eax = 0 - success |
3259 | * eax = 1 - the receiver has not defined buffer for IPC messages |
||
3260 | (can be, still have no time, |
||
3261 | and can be, this is not right process) |
||
3262 | * eax = 2 - the receiver has blocked IPC-buffer; try to wait a bit |
||
3263 | * eax = 3 - overflow of IPC-buffer of the receiver |
||
114 | mikedld | 3264 | * eax = 4 - process/thread with such PID does not exist |
3265 | Remarks: |

118 | diamond | 3266 | * Immediately after writing of IPC-message to the buffer the system |
3267 | sends to the receiver the event with code 7 (see event codes). |

118 | diamond | 3270 | ==== Function 61 - get parameters for the direct graphics access. ==== |
114 | mikedld | 3271 | ====================================================================== |
118 | diamond | 3272 | The data of the graphics screen (the memory area which displays |
3273 | screen contents) are accessible to a program directly, without |
||
3274 | any system calls, through the selector gs: |
||
131 | diamond | 3275 | mov eax, [gs:0] |
118 | diamond | 3276 | places in eax the first dword of the buffer, which contains |
3277 | information on color of the left upper point (and, possibly, colors |
||
3278 | of several following). |
||
131 | diamond | 3279 | mov [gs:0], eax |
118 | diamond | 3280 | by work in VESA modes with LFB sets color of the left upper point |
3281 | (and, possibly, colors of several following). |
||
3282 | To interpret the data of graphics screen program needs to know |
||
3283 | some parameters, returning by this function. |
||
114 | mikedld | 3284 | Remarks: |
118 | diamond | 3285 | * Graphics parameters changes very seldom at work, |
3286 | namely, only in cases, when user works with the application VRR. |
||
3287 | * At videomode change the system redraws all windows (event |
||
3288 | with code 1) and redraws the background (event 5). |
||
3289 | Same events occur in other cases too, which meet much more often, |
||
3290 | than videomode change. |
||
3291 | * By operation in videomodes with LFB the selector gs points to |
||
3292 | LFB itself, so reading/writing on gs result directly in |
||
3293 | change of screen contents. By operation in videomodes without |
||
3294 | LFB gs points to some data area in the kernel, and all functions |
||
3295 | of screen output fulfil honesty double operation on writing |
||
3296 | directly to the screen and writing to this buffer. In result |
||
3297 | at reading contents of this buffer the results correspond to |
||
3298 | screen contents (with, generally speaking, large color |
||
3299 | resolution), and writing is ignored. |
||
3300 | One exception is the mode 320*200, for which main loop of the |
||
3301 | system thread updates the screen according to mouse movements. |

118 | diamond | 3438 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 3439 | ====================================================================== |
118 | diamond | 3440 | The debug board is the global system buffer (with the size |
3441 | 512 bytes), to which any program can write (generally speaking, |
||
3442 | arbitrary) data and from which other program can read these data. |
||
3443 | By the agreement written data are text strings interpreted as |
||
3444 | debug messages on a course of program execution. The kernel in |
||
3445 | some situations also writes to the debug board information on |
||
3446 | execution of some functions; by the agreement kernel messages |
||
3447 | begins from the prefix "K : ". |
||
3448 | For view of the debug board the application 'board' was created, |
||
3449 | which reads data from the buffer and displays them in its window. |
||
3450 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
3451 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 3452 | but also does not prevent. |
118 | diamond | 3453 | Because debugger has been written, the value of the debug board |
3454 | has decreased, as debugger allows to inspect completely a course of |
||
3455 | program execution without any efforts from the direction of program |
||
3456 | itself. Nevertheless in some cases the debug board is still useful. |
||
114 | mikedld | 3457 | |

114 | mikedld | 3463 | Returned value: |
3464 | * function does not return value |
||
3465 | Remarks: |
||
118 | diamond | 3466 | * Byte is written to the buffer. Buffer size is 512 bytes. |
3467 | At buffer overflow all obtained data are lost. |
||
3468 | * For output to the debug board of more complicated objects |
||
3469 | (strings, numbers) it is enough to call this function in cycle. |
||
3470 | It is possible not to write the appropriate code manually and use |
||
3471 | file 'debug.inc', which is included into the distributive. |

118 | diamond | 3536 | -------------- Subfunction 4 - set system-wide hotkey. --------------- |
3537 | When hotkey is pressed, the system notifies only those applications, |
||
3538 | which have installed it; the active application (which receives |
||
3539 | all normal input) does not receive such keys. |
||
3540 | The notification consists in sending event with the code 2. |
||
3541 | Reading hotkey is the same as reading normal key - by function 2. |
||
114 | mikedld | 3542 | Parameters: |
118 | diamond | 3543 | * eax = 66 - function number |
3544 | * ebx = 4 - subfunction number |
||
3545 | * cl determines key scancode; |
||
3546 | use cl=0 to give combinations such as Ctrl+Shift |
||
3547 | * edx = 0xXYZ determines possible states of control keys: |
||
3548 | * Z (low 4 bits) determines state of LShift and RShift: |
||
3549 | * 0 = no key must be pressed; |
||
3550 | * 1 = exactly one key must be pressed; |
||
3551 | * 2 = both keys must be pressed; |
||
3552 | * 3 = must be pressed LShift, but not RShift; |
||
3553 | * 4 = must be pressed RShift, but not LShift |
||
3554 | * Y - similar for LCtrl and RCtrl; |
||
3555 | * X - similar for LAlt and RAlt |
||
114 | mikedld | 3556 | Returned value: |
118 | diamond | 3557 | * eax=0 - success |
3558 | * eax=1 - too mant hotkeys (maximum 256 are allowed) |
||
114 | mikedld | 3559 | Remarks: |
118 | diamond | 3560 | * Hotkey can work either at pressing or at release. Release |
3561 | scancode of a key is more on 128 than pressing scancode |
||
3562 | (i.e. high bit is set). |
||
3563 | * Several applications can set the same combination; |
||
3564 | all such applications will be informed on pressing |
||
3565 | such combination. |

||
3571 | * cl = scancode of key and edx = 0xXYZ the same as in subfunction 4 |
||
114 | mikedld | 3572 | Returned value: |
118 | diamond | 3573 | * eax = 0 - success |
114 | mikedld | 3574 | * eax = 1 - there is no such hotkey |
3575 | Remarks: |
||
118 | diamond | 3576 | * When a process/thread terminates, all hotkey installed by it are |
3577 | deleted. |
||
3578 | * The call to this subfunction does not affect other applications. |
||
3579 | If other application has defined the same combination, it will |
||
3580 | still receive notices. |

||
3592 | * function does not return value |
||
3593 | Remarks: |
||
118 | diamond | 3594 | * The value -1 for a parameter means "do not change"; e.g. to move |
3595 | the window without resizing it is possible to specify edx=esi=-1. |
||
3596 | * Previously the window must be defined by function 0. |
||
114 | mikedld | 3597 | It sets initial coordinates and sizes of the window. |
118 | diamond | 3598 | * Sizes of the window are understood in sense of function 0, |
3599 | that is one pixel less than real sizes. |
||
3600 | * The function call for maximized windows is simply ignored. |
||
3601 | * For windows of appropriate styles position and/or sizes can be |
||
3602 | changed by user; current position and sizes can be obtained by |
||
3603 | call to function 9. |
||
3604 | * The function sends to the window redraw event (with the code 1). |

4432 | * 4 = reserved (in current implementation never comes even after |
||
4433 | unmasking by function 40) |
||
4434 | * 5 = the desktop background is redrawed (is reset automatically |
||
4435 | after redraw, so if in redraw time program does not wait and |
||
4436 | does not check events, it will not remark this event) |
||
4437 | * 6 = mouse event (something happened - button pressing or moving; |
||
4438 | is reset at reading) |

4439 | * 7 = IPC event (see function 60 - |
||
4440 | Inter Process Communication; is reset at reading) |
