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. |
||
114 | mikedld | 7 | |

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. |
||

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 | |

||
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): |

||
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. |

295 | for close of the window with identifier 1 and |
||
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. |

350 | at least one thread. One process can create many threads, |
||
351 | in this case each thread has its own slot and the fields |

352 | +10, +22, +26 in these slots coincide. |
||
353 | Applications have no common way to define whether two threads |
||
114 | mikedld | 354 | belong to one process. |
118 | diamond | 355 | * The active window - window on top of the window stack - |
356 | receives the messages on a keyboard input. For such window |
||
357 | the position in the window stack coincides with returned value. |
||
358 | * Slot 1 corresponds to special system thread, for which: |
||
359 | * the window is in the bottom of the window stack, the fields |
||
360 | +4 and +6 contain value 1 |
||
361 | * name of the process - "OS/IDLE" (supplemented by spaces) |
||
362 | * address of the process in memory is 0, size of used memory is |
||
114 | mikedld | 363 | 16 Mb (0x1000000) |
364 | * PID=1 |
||
118 | diamond | 365 | * coordinates and sizes of the window are by convention set to 0 |
366 | * status of the slot is always 0 (running) |
||
367 | * the execution time adds of time leaving on operations itself |
||
368 | and idle time in waiting for interrupt (which can be got by call |
||
369 | to subfunction 4 of function 18). |
||
370 | * Beginning from slot 2, the normal applications are placed. |
||
371 | * The normal applications are placed in memory at the address |
||
372 | 0x10000000 (kernel constand 'std_application_base_address'). |
||
373 | There is no intersection, as each process has its own page table. |
||
374 | * At creation of the thread it is assigned the slot |
||
375 | in the system table and identifier (Process/Thread IDentifier = |
||
376 | PID/TID), which do not vary with time for given thread. |
||
377 | After completion of the thread its slot can be anew used |
||
378 | for another thread. The thread identifier can not be assigned |
||
379 | to other thread even after completion of this thread. |
||
380 | Identifiers, assigned to new threads, grow monotonously. |
||
381 | * If the thread has not yet defined the window by call to |
||
382 | function 0, the position and the sizes |
||
383 | of its window are considered to be zero. |
||
384 | * At the moment only the part of the buffer by a size |
||
385 | 52 = 0x34 bytes is used. Nevertheless it is recommended to use |
||
386 | 1-Kb buffer for the future compatibility, in the future |
||
387 | some fields can be added. |

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

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

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

1369 | * Alarm clock can be set on operation in the given time every day. |
||
1370 | But there is no existing system function to disable it. |
||
1371 | * Operation of alarm clock consists in generation IRQ8. |
||
1372 | * Generally CMOS supports for alarm clock set of value 0xFF |

||
2203 | * (left,top) are coordinates of the left upper corner, |
||
2204 | (right,bottom) are coordinates of the right lower one. |
||
2205 | Thus the size of working area on x axis can be calculated by |
||
2206 | formula right-left+1, on y axis - by formula bottom-right+1. |
||
2207 | * See also function 14, |

2225 | which set working area to all screen without system panel. |
||
2226 | * (left,top) are coordinates of the left upper corner, |
||
2227 | (right,bottom) are coordinates of the right lower one. |
||
2228 | Thus the size of working area on x axis can be calculated by |
||
2229 | formula right-left+1, on y axis - by formula bottom-right+1. |
||
2230 | * If 'left'>='right', x-coordinate of working area is not changed. |
||
2231 | If 'left'<0, 'left' will not be set. If 'right' is greater than or |
||
2232 | equal to screen width, 'right' will not be set. |
||
2233 | Similarly on y axis. |
||
2234 | * See also function 14, |

||
114 | mikedld | 2325 | Returned value: |
2326 | * function does not return value |
||
2327 | Remarks: |
||
118 | diamond | 2328 | * Default scale is 0 (scale factor is 1). If in the shape data |
2329 | one byte corresponds to one pixel, there is no necessity |
||
2330 | to set scale. |
||
2331 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2332 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2333 | functions 0, 67. |
118 | diamond | 2334 | * On definition of scale xsize and ysize must be divisible |
2335 | on 2^scale. |
||
2336 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2337 | to a window of square with the side 2^scale (if scale=0, |
||
2338 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2339 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2340 | * Data size: (xsize shr scale)*(ysize shr scale). |
2341 | * Data must be presented in the memory and not change |
||
2342 | after set of shape. |
||
2343 | * The system views the shape data at every window redraw by |
||
2344 | function 0. |
||
2345 | * The call of subfunction 0 with NULL pointer results in return |
||
2346 | to the rectangular shape. |

2867 | for convenience of transition to the future extensions. |
||
2868 | * Limitation n<=39 is imposed. |

118 | diamond | 2896 | * ebx = pointer to the information structure |
2897 | Format of the information structure: |

2899 | * +4: dword: first block to read (beginning from 0) |

||
2901 | * +12 = +0xC: dword: pointer to buffer for data |

114 | mikedld | 2903 | (4096 bytes) |
118 | diamond | 2904 | * +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
2905 | given in the general description |
||
114 | mikedld | 2906 | Returned value: |
118 | diamond | 2907 | * eax = 0 - success, otherwise file system error code |
2908 | * ebx = file size (in bytes) or -1=0xffffffff, if file was not found |
||
114 | mikedld | 2909 | Remarks: |
118 | diamond | 2910 | * Block size is 512 bytes. |
114 | mikedld | 2911 | * This function is obsolete, for reading files use subfunction 0 |
118 | diamond | 2912 | of function 70, for reading folders - subfunction 1 of |
2913 | function 70. |
||
2914 | * Function can read contents of a folder. Only FAT file system is |
||
2915 | supported. The format of FAT-folder is described |
||
2916 | in any FAT documentation. |
||
2917 | * Size of a folder is determined by size of FAT clusters chain. |
||
2918 | * If file was ended before last requested block was read, |
||
2919 | the function will read as many as it can, and after that return |
||
2920 | eax=6 (EOF). |
||
2921 | * Function can read root folders /rd/1,/fd/x,/hd[n]/x, but |
||
2922 | in the first two cases the current implementation does not follow |
||
2923 | to the declared rules: |
||
114 | mikedld | 2924 | for /rd/1: |
118 | diamond | 2925 | * if one want to read 0 blocks, function considers, |
2926 | that he requested 1; |
||
2927 | * if one requests more than 14 blocks or starting block is |
||
2928 | not less than 14, function returns eax=5 (not found) и ebx=-1; |
||
2929 | * size of ramdisk root folder is 14 blocks, |
||
2930 | 0x1C00=7168 байт; but function returns ebx=0 |
||
2931 | (except of the case of previous item); |
||
2932 | * strangely enough, it is possible to read 14th block (which |
||
2933 | generally contains a garbage - I remind, the indexing begins |
||
2934 | from 0); |
||
2935 | * if some block with the number not less than 14 was requested, |
||
2936 | function returns eax=6(EOF); otherwise eax=0. |
||
2937 | For /fd/x: |
||
2938 | * if the start block is not less than 14, function returns |
||
2939 | eax=5 (not found) and ebx=0; |
||
2940 | * note that format of FAT12 allows floppies with the root size |
||
2941 | more or less than 14 blocks; |
||
2942 | * check for length is not performed; |
||
2943 | * if data was successful read, function returns |
||
2944 | eax=0,ebx=0; otherwise eax=10 (access denied), ebx=-1. |
||
2945 | * The function handles reading of special folders /,/rd,/fd,/hd[n]; |
||
2946 | but the result does not correspond to expected (on operations with |
||
2947 | normal files/folders), does not follow the declared rules, |
||
2948 | may be changed in future versions of the kernel and consequently |
||
2949 | is not described. To obtain the information about the equipment |
||
2950 | use subfunction 11 of function 18 or |
||
2951 | read corresponding folder with subfunction 1 of function 70. |

3137 | only registers eax,ebx,ecx (from pushad-structure transmitted |

||
118 | diamond | 3200 | * +60 = +0x3C: dword: eax (=number of system function) |
114 | mikedld | 3201 | Remarks: |
118 | diamond | 3202 | * The function is used only in the application 'systrace'. |
3203 | It is rather difficult to imagine a situation, in which |
||
3204 | this application or this function are really useful; |
||
3205 | and all system calls for support of this function are a little |
||
3206 | decelerated (though not strongly)... |
||
3207 | * So there is a proposition to delete from the kernel |
||
3208 | support of this function, together with application 'systrace'. |
||
3209 | * The information on system calls saves in the system |
||
3210 | ring buffer with 0x10 entries. |
||
3211 | This function simply copies the given size of data |
||
3212 | from this buffer to the given address. |
||
3213 | * One can determine, which entry in the buffer corresponds to |
||
3214 | last system call, by value of eax, namely, it is the entry |
||
3215 | (eax and 0xF) (at offset (eax and 0xF)*0x40). |
||
3216 | * In the current implementation there can be the seldom |
||
3217 | meeting problems of unsynchronization, when the information |
||
3218 | on some calls becomes outdated. |
||
3219 | * Under the system buffer one page, 4Kb, is allocated. |
||
3220 | Size of an entry = 64 bytes. Why only 16 entries are used, |
||
3221 | is not clearly. |
||
3222 | * The value of esp at the moment of system call cannot |
||
3223 | be determined by this function. |
||
3224 | * The current implementation does not check edx for correctness. |

118 | diamond | 3227 | ========== Function 60 - Inter Process Communication (IPC). ========== |
114 | mikedld | 3228 | ====================================================================== |
118 | diamond | 3229 | IPC is used for message dispatching from one process/thread to |
3230 | another. Previously it is necessary to agree how to interpret |
||
114 | mikedld | 3231 | the concrete message. |
3232 | |||
118 | diamond | 3233 | ----------- Subfunction 1 - set the area for IPC receiving ----------- |
3234 | Is called by process-receiver. |
||
114 | mikedld | 3235 | Parameters: |
118 | diamond | 3236 | * eax = 60 - function number |
3237 | * ebx = 1 - subfunction number |
||
3238 | * ecx = pointer to the buffer |
||
3239 | * edx = size of the buffer |

114 | mikedld | 3240 | Returned value: |
118 | diamond | 3241 | * eax = 0 - always success |
3242 | Format of IPC-buffer: |

3245 | buffer data are not changed from outside (no new messages) |
||
114 | mikedld | 3246 | * +4: dword: occupied place in the buffer (in bytes) |
3247 | * +8: first message |

118 | diamond | 3255 | ------------------ Subfunction 2 - send IPC message ------------------ |
3256 | Is called by process-sender. |
||
114 | mikedld | 3257 | Parameters: |
118 | diamond | 3258 | * eax = 60 - function number |
3259 | * ebx = 2 - subfunction number |
||
114 | mikedld | 3260 | * ecx = PID of receiver |
118 | diamond | 3261 | * edx = pointer to the message data |
3262 | * esi = message length (in bytes) |
||
114 | mikedld | 3263 | Returned value: |
118 | diamond | 3264 | * eax = 0 - success |
3265 | * eax = 1 - the receiver has not defined buffer for IPC messages |
||
3266 | (can be, still have no time, |
||
3267 | and can be, this is not right process) |
||
3268 | * eax = 2 - the receiver has blocked IPC-buffer; try to wait a bit |
||
3269 | * eax = 3 - overflow of IPC-buffer of the receiver |
||
114 | mikedld | 3270 | * eax = 4 - process/thread with such PID does not exist |
3271 | Remarks: |
||
118 | diamond | 3272 | * Immediately after writing of IPC-message to the buffer the system |
3273 | sends to the receiver the event with code 7 (see event codes). |

118 | diamond | 3276 | ==== Function 61 - get parameters for the direct graphics access. ==== |
114 | mikedld | 3277 | ====================================================================== |
118 | diamond | 3278 | The data of the graphics screen (the memory area which displays |
3279 | screen contents) are accessible to a program directly, without |
||
3280 | any system calls, through the selector gs: |
||
131 | diamond | 3281 | mov eax, [gs:0] |
118 | diamond | 3282 | places in eax the first dword of the buffer, which contains |
3283 | information on color of the left upper point (and, possibly, colors |
||
3284 | of several following). |
||
131 | diamond | 3285 | mov [gs:0], eax |
118 | diamond | 3286 | by work in VESA modes with LFB sets color of the left upper point |
3287 | (and, possibly, colors of several following). |
||
3288 | To interpret the data of graphics screen program needs to know |
||
3289 | some parameters, returning by this function. |
||
114 | mikedld | 3290 | Remarks: |
118 | diamond | 3291 | * Graphics parameters changes very seldom at work, |
3292 | namely, only in cases, when user works with the application VRR. |
||
3293 | * At videomode change the system redraws all windows (event |
||
3294 | with code 1) and redraws the background (event 5). |
||
3295 | Same events occur in other cases too, which meet much more often, |
||
3296 | than videomode change. |
||
3297 | * By operation in videomodes with LFB the selector gs points to |
||
3298 | LFB itself, so reading/writing on gs result directly in |
||
3299 | change of screen contents. By operation in videomodes without |
||
3300 | LFB gs points to some data area in the kernel, and all functions |
||
3301 | of screen output fulfil honesty double operation on writing |
||
3302 | directly to the screen and writing to this buffer. In result |
||
3303 | at reading contents of this buffer the results correspond to |
||
3304 | screen contents (with, generally speaking, large color |
||
3305 | resolution), and writing is ignored. |
||
3306 | One exception is the mode 320*200, for which main loop of the |
||
3307 | system thread updates the screen according to mouse movements. |

118 | diamond | 3444 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 3445 | ====================================================================== |
118 | diamond | 3446 | The debug board is the global system buffer (with the size |
3447 | 512 bytes), to which any program can write (generally speaking, |
||
3448 | arbitrary) data and from which other program can read these data. |
||
3449 | By the agreement written data are text strings interpreted as |
||
3450 | debug messages on a course of program execution. The kernel in |
||
3451 | some situations also writes to the debug board information on |
||
3452 | execution of some functions; by the agreement kernel messages |
||
3453 | begins from the prefix "K : ". |
||
3454 | For view of the debug board the application 'board' was created, |
||
3455 | which reads data from the buffer and displays them in its window. |
||
3456 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
3457 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 3458 | but also does not prevent. |
118 | diamond | 3459 | Because debugger has been written, the value of the debug board |
3460 | has decreased, as debugger allows to inspect completely a course of |
||
3461 | program execution without any efforts from the direction of program |
||
3462 | itself. Nevertheless in some cases the debug board is still useful. |
||
114 | mikedld | 3463 | |

114 | mikedld | 3469 | Returned value: |
3470 | * function does not return value |
||
3471 | Remarks: |
||
118 | diamond | 3472 | * Byte is written to the buffer. Buffer size is 512 bytes. |
3473 | At buffer overflow all obtained data are lost. |
||
3474 | * For output to the debug board of more complicated objects |
||
3475 | (strings, numbers) it is enough to call this function in cycle. |
||
3476 | It is possible not to write the appropriate code manually and use |
||
3477 | file 'debug.inc', which is included into the distributive. |

118 | diamond | 3542 | -------------- Subfunction 4 - set system-wide hotkey. --------------- |
3543 | When hotkey is pressed, the system notifies only those applications, |
||
3544 | which have installed it; the active application (which receives |
||
3545 | all normal input) does not receive such keys. |
||
3546 | The notification consists in sending event with the code 2. |
||
3547 | Reading hotkey is the same as reading normal key - by function 2. |
||
114 | mikedld | 3548 | Parameters: |
118 | diamond | 3549 | * eax = 66 - function number |
3550 | * ebx = 4 - subfunction number |
||
3551 | * cl determines key scancode; |
||
3552 | use cl=0 to give combinations such as Ctrl+Shift |
||
3553 | * edx = 0xXYZ determines possible states of control keys: |
||
3554 | * Z (low 4 bits) determines state of LShift and RShift: |
||
3555 | * 0 = no key must be pressed; |
||
3556 | * 1 = exactly one key must be pressed; |
||
3557 | * 2 = both keys must be pressed; |
||
3558 | * 3 = must be pressed LShift, but not RShift; |
||
3559 | * 4 = must be pressed RShift, but not LShift |
||
3560 | * Y - similar for LCtrl and RCtrl; |
||
3561 | * X - similar for LAlt and RAlt |
||
114 | mikedld | 3562 | Returned value: |
118 | diamond | 3563 | * eax=0 - success |
3564 | * eax=1 - too mant hotkeys (maximum 256 are allowed) |
||
114 | mikedld | 3565 | Remarks: |
118 | diamond | 3566 | * Hotkey can work either at pressing or at release. Release |
3567 | scancode of a key is more on 128 than pressing scancode |
||
3568 | (i.e. high bit is set). |
||
3569 | * Several applications can set the same combination; |
||
3570 | all such applications will be informed on pressing |
||
3571 | such combination. |

114 | mikedld | 3578 | Returned value: |
118 | diamond | 3579 | * eax = 0 - success |
114 | mikedld | 3580 | * eax = 1 - there is no such hotkey |
3581 | Remarks: |
||
118 | diamond | 3582 | * When a process/thread terminates, all hotkey installed by it are |
3583 | deleted. |
||
3584 | * The call to this subfunction does not affect other applications. |
||
3585 | If other application has defined the same combination, it will |
||
3586 | still receive notices. |

118 | diamond | 3600 | * The value -1 for a parameter means "do not change"; e.g. to move |
3601 | the window without resizing it is possible to specify edx=esi=-1. |
||
3602 | * Previously the window must be defined by function 0. |
||
114 | mikedld | 3603 | It sets initial coordinates and sizes of the window. |
118 | diamond | 3604 | * Sizes of the window are understood in sense of function 0, |
3605 | that is one pixel less than real sizes. |
||
3606 | * The function call for maximized windows is simply ignored. |
||
3607 | * For windows of appropriate styles position and/or sizes can be |
||
3608 | changed by user; current position and sizes can be obtained by |
||
3609 | call to function 9. |
||
3610 | * The function sends to the window redraw event (with the code 1). |

4440 | * 5 = the desktop background is redrawed (is reset automatically |
||
4441 | after redraw, so if in redraw time program does not wait and |
||
4442 | does not check events, it will not remark this event) |
||
4443 | * 6 = mouse event (something happened - button pressing or moving; |
||
4444 | is reset at reading) |
