114 | mikedld | 1 | SYSTEM FUNCTIONS of OS Kolibri 0.5.8.1 |
2 | |||
3 | Number of the function is located in the register eax. |
||
4 | The call of the system function is carried out by the command "int 0x40". |
||
5 | All registers, except for obviously indicated in returned value, |
||
6 | including the register of flags eflags, are saved. |
||

9 | ====================================================================== |
||
10 | ============== Function 0 - define and draw the window. ============== |
||
11 | ====================================================================== |
||
12 | Defines an application window. Draws a frame of the window, header and |
||
13 | working area. For windows with скином defines standard buttons of closing |
||
14 | and minimization. |
||
15 | Parameters: |
||
16 | * eax = 0 - number of the function |
||
17 | * ebx = [coordinate on axis x]*65536 + [size on axis x] |
||
18 | * ecx = [coordinate on axis y]*65536 + [size on axis y] |
||
19 | * edx = 0xXYRRGGBB, where: |
||
20 | * Y = style of the window: |
||
21 | * Y=0 - type I - window of the fixed sizes |
||
22 | * Y=1 - only to define window area, nothing to draw |
||
23 | * Y=2 - type II - window with changed sizes |
||
24 | * Y=3 - window with skinned |
||
25 | * other possible values (from 4 up to 15) reserved, |
||
26 | function call with such Y is ignored |
||
27 | * RR, GG, BB = accordingly red, green, blue |
||
28 | colours of a working area of the window |
||
29 | (is ignored for style Y=2) |
||
30 | * X = DCBA (bits) |
||
31 | * A = 1 - window has caption; if Y=3, caption string address could be passed in edi, |
||
32 | otherwise use function 71 subfunction 1 |
||
33 | * B = 1 - draw all graphics primitives relative to window client area |
||
34 | * C - reserved |
||
35 | * D = 8 - fill client area with gradient |
||
36 | other values are reserved |
||
37 | The following parameters are intended for windows of a type I and II, |
||
38 | and ignored for styles Y=1,3: |
||
39 | * esi = 0xXYRRGGBB - colour of header |
||
40 | * RR, GG, BB define colour |
||
41 | * Y=0 - usual window, Y=1 - unmovable window |
||
42 | * X defines a gradient of header: X=0 - no gradient, |
||
43 | X=8 - usual gradient, |
||
44 | for windows of a type II X=4 - negative gradient |
||
45 | * other values X and Y reserved |
||
46 | * edi = 0x00RRGGBB - colour of a frame |
||
47 | Returned value: |
||
48 | * function does not return value |
||
49 | Remarks: |
||
50 | * Location and the sizes of the window are installed by the first call of |
||
51 | this function and are ignored at subsequent; for change of location |
||
52 | and/or of sizes already of created window use function 67. |
||
53 | * If to use windows of appropriate styles, location and - or the sizes of |
||
54 | the window can vary by the user. |
||
55 | Current location and the sizes can be obtained by function 9. |
||
56 | * The window should be located on the screen. If the transferred coordinates |
||
57 | nd the sizes do not satisfy to this condition, appropriate coordinate |
||
58 | (or, probably, is considered both) as zero, and if also it does not help, |
||
59 | the appropriate size (or, probably, both) is installed in a size of the |
||
60 | screen. |
||
61 | |||
62 | Further we shall designate xpos, ypos, xsize, ysize - values transmitted |
||
63 | in ebx, ecx. The coordinates are resulted concerning the left upper corner |
||
64 | of the window, which, thus, is set as (0,0), coordinate of the right lower |
||
65 | corner essence (xsize, ysize). |
||
66 | * The sizes of the window are understood in sense of coordinates of the |
||
67 | right lower corner. This concerns and to all other functions. It means, |
||
68 | that the real sizes on 1 pixel are more. |
||
69 | * Look of the window of a type I: |
||
70 | * draw external frame of colour indicated in edi, |
||
71 | in width 1 pixel |
||
72 | * draw header - rectangle with the left upper corner (1,1) and right lower |
||
73 | (xsize-1, min (25, ysize)) colour indicated in esi |
||
74 | (in view of a gradient) |
||
75 | * If ysize > =26, the working area of the window - rectangle with the left |
||
76 | upper corner (1,21) and right lower |
||
77 | (xsize-1, ysize-1) (sizes (xsize-1) * (ysize-21)) - colour |
||
78 | indicated in edx (in view of a gradient) is painted over |
||
79 | * Look of the window of a type Y=1: |
||
80 | * completely defined by the application |
||
81 | * Look of the window of a type II: |
||
82 | * draw external frame of width 1 pixel of the "shaded" colour |
||
83 | edi (all making colours decrease twice) |
||
84 | * drawn intermediate frame of width 3 pixels of colour edi |
||
85 | * draw internal frame of width 1 pixel |
||
86 | "shaded" colour edi |
||
87 | * draw header - rectangle with the left upper corner (4,4) |
||
88 | and right lower (xsize-4,min(20,ysize)) colour, indicated в esi |
||
89 | (in view of a gradient) |
||
90 | * If ysize > =26, the working area of the window is painted over - |
||
91 | rectangle with the left upper corner (5,20) and right lower |
||
92 | (xsize-5,ysize-5) - colour indicated in edx (in view of a gradient) |
||
93 | * Look of the window with skinned: |
||
94 | * draw external frame of width 1 pixel |
||
95 | colour 'outer' from skin |
||
96 | * draw intermediate framework of width 3 pixels |
||
97 | colour 'frame' from skin |
||
98 | * draw internal framework of width 1 pixel |
||
99 | colour 'inner' from skin |
||
100 | * draw header (on pictures from skin) in a rectangle |
||
101 | (0,0) - (xsize,_skinh-1) |
||
102 | * If ysize > =26, the working area of the window is painted over - |
||
103 | rectangle with the left upper corner (5, _skinh) and right lower |
||
104 | (xsize-5,ysize-5) - colour indicated in edx (in view of a gradient) |
||
105 | * two standard buttons are defined: closings and minimizations |
||
106 | (see function 8) |
||
107 | * value _skinh is accessible as result of call |
||
108 | subfunction 4 functions 48 |
||
109 | |||
110 | ====================================================================== |
||
111 | ================= Function 1 - put a point in the window. ============ |
||
112 | ====================================================================== |
||
113 | Parameters: |
||
114 | * eax = 1 - number of the function |
||
115 | * ebx = x-coordinate (concerning the window) |
||
116 | * ecx = y-coordinate (concerning the window) |
||
117 | * edx = 0x00RRGGBB - colour of a point |
||
118 | edx = 0x01xxxxxx - to invert colour of a point |
||
119 | (low 24 bits ignored) |
||
120 | Returned value: |
||
121 | * function does not return value |
||
122 | |||
123 | ====================================================================== |
||
124 | ======== Function 2 - receive the code of the pressed key. =========== |
||
125 | ====================================================================== |
||
126 | Takes away the code of the pressed key from the buffer. |
||
127 | Parameters: |
||
128 | * eax = 2 - number of the function |
||
129 | Returned value: |
||
130 | * if the buffer is empty, comes back eax=1 |
||
131 | * If the buffer is nonblank, that comes back al=0, ah=code of the pressed key, |
||
132 | high word of the register eax is set zero |
||
133 | * If there is "hotkey", comes back |
||
134 | al=2, ah=scancode of the pressed key (0 for direction keys), |
||
135 | high word of the register eax contains a status of direction keys |
||
136 | at the moment of pressing a hotkey |
||
137 | Remarks: |
||
138 | * There is a common system buffer of the pressed keys by a size of 120 bytes, |
||
139 | organized as queue. |
||
140 | * There is one more common system buffer on 120 "hotkey". |
||
141 | * By call of this function the application with the inactive window |
||
142 | considers, that the buffer of the pressed keys is empty. |
||
143 | * By default this function returns ASCII-codes; to switch to the mode |
||
144 | scancode (and back) it is possible with usage of the function 66. |
||
145 | However, the hotkey always come back as scancodes. |
||
146 | * Ffind out, what keys correspond to what codes, is possible, having started |
||
147 | the applications keyascii and scancode. |
||
148 | * Scancodes come back directly by keyboard and are fixed; ASCII-codes turn |
||
149 | out with usage of the conversion tables, which can be installed |
||
150 | subfunction 2 functions 21 and to read subfunction 2 functions 26. |
||
151 | * As a consequence, ASCII-codes take into account current keyboard layout |
||
152 | (rus/en) as against scancodes. |
||
153 | * The information only about those hotkeys acts which were defined by this |
||
154 | stream subfunction 4 functions 66. |
||
155 | |||

||
164 | for time 23:59:59 result will be 0x00595923 |
||
165 | Remarks: |
||
166 | * Look also subfunction 9 functions 26 - obtaining of time from the moment |
||
167 | of start of the system; it in many cases is more convenient, as returns |
||
168 | simply DWORD-value of the counter of time. |
||
169 | * System time can be installed by the function 22. |
||
170 | |||
171 | ====================================================================== |
||
172 | ================ Function 4 - draw text in the window. =============== |
||
173 | ====================================================================== |
||
174 | Can output both strings with given length and NULL-terminated strings |
||
175 | (0x0) - ASCIIZ(string db 'text',0). To draw ASCIIZ string, pass -1 |
||
176 | in esi (mov esi,-1). |
||
177 | Parameters: |

186 | Returned value: |
||
187 | * function does not return value |
||
188 | Remarks: |
||
189 | * The first system font is read out at loading from the file char.mt, |
||
190 | second system font - from char2.mt. |
||
191 | * Both fonts have height 9 pixels, width of the monowide font |
||
192 | is equal 6 pixels. |
||
193 | |||
194 | ====================================================================== |

||
205 | and at all does not make any operations. If really it is required to |
||
206 | transfer handle to the following process (to complete a current time |
||
207 | slice), use subfunction of 1 function 68. |
||
208 | * At current realization there will be an immediate return from the function, |
||
209 | if the addition ebx with current value of the counter of time will call |
||

280 | there are two standard buttons - closing of the window with the |
||
281 | identifier 1 and minimization of the window with the identifier 0xffff. |
||
282 | * The creation of two buttons with identical identifiers is admitted. |
||
283 | * The button with the identifier 0xffff at pressing is interpreted by the |

298 | * eax = maximum number of the slot of thread |
||
299 | * buffer, which specifies ebx, contains the following information: |
||
300 | * +0: dword: usage of the processor (how many clock ticks per one second |
||
301 | leaves on fulfilment of this thread) |
||
302 | * +4: word: position of the window of thread in the window stack |
||
303 | * +6: word: (there is no ratio to the requested thread) |
||
304 | number of the slot thread, which window is in the window stack |
||
305 | in a position ecx |
||
306 | * +8: word: reserved |
||
307 | * +10 = +0xA: 11 bytes: name of the process |
||
308 | (name of an appropriate executable file in the format 8+3) |

318 | * 0 = thread worked |
||
319 | * 1 = thread paused |
||
320 | * 2 = thread paused at the moment of waiting event |
||
321 | * 3 = thread completed as a result of function call -1 or |
||
322 | under duress as a consequence of call subfunction 2 functions 18 |
||
323 | or termination of the system |
||
324 | * 4 = thread is completed as a result of exception |
||
325 | * 5 = thread wait event |
||
326 | * 9 = requested slot is free, |
||
327 | all other information on the slot is not meaningful |
||
328 | Remarks: |
||
329 | * Slots are numbered with 1. |
||
330 | * Returned value not is a total number of streams, as there are free slots. |
||
331 | * При создании процесса автоматически создается thread выполнения. |
||
332 | * Function produces the information on thread. Each process has even one |
||
333 | thread. One process can create some thread, in this case everyone thread |
||
334 | receives the slot, and the fields +10, +22, +26 in these slots coincide. |
||
335 | For the applications there is no common way to define, whether two thread |
||
336 | belong to one process. |
||
337 | * Active window - window which is taking place on top of the window stack, |
||
338 | it receives the messages on a keyboard input. For it the position in the |
||
339 | window stack coincides with returned value. |
||
340 | * Slot 1 corresponds to special thread of an operating system, for which: |
||
341 | * window is in the bottom of the window stack, the fields +4 and +6 |
||
342 | contain value 1 |
||
343 | * Nname of the process - "OS/IDLE" (supplemented by blanks) |
||
344 | * address of the process is equal memory 0, size of used memory |
||
345 | 16 Mb (0x1000000) |
||
346 | * PID=1 |
||
347 | * coordinates and sizes of the window conditionally rely equal 0 |
||
348 | * status of the slot - always 0 (worked) |
||
349 | * The execution time adds of time leaving on purely operation, and down |
||
350 | time in waiting interruption (which can be received by call |
||
351 | subfunction 4 functions 18). |
||
352 | * Since the slot 2, the usual applications are placed. |
||
353 | * Usual applications are placed in memory to the address 0x10000000 |
||
354 | (constant of a kernel std_application_base_address). |
||
355 | Intersection does not occur, as for each process the own page table. |
||
356 | * At creation thread to it are assigned the slot in the system table and |
||
357 | identifier (Process/Thread IDentifier = PID/TID), which for given thread |
||
358 | do not vary in the subsequent time. |
||
359 | After completion thread its slot can be anew used for another thread. |
||
360 | The identifier thread can not be assigned to other stream even after |
||
361 | completion first. |
||
362 | Identifiers, assigned to new thread, monotonously grow. |
||
363 | * If thread yet has not defined the window by function call 0, |
||
364 | a location and the sizes of this window rely in zero. |
||
365 | * In the given moment the part of the buffer by a size 52 = 0x34 of byte |
||
366 | is used only. Nevertheless it is recommended to use the buffer |
||
367 | by a size 1 KB for the future compatibility, in the future some fields |
||
368 | can be added. |

||
2763 | Parameters: |
||
2764 | * eax = 58 |
||
2765 | * ebx = pointer on information structure |
||
2766 | Format of information structure: |
||
2767 | * +0: dword: 0 = number subfunction |
||
2768 | * +4: dword: number of block for reading (beginning from 0) |
||
2769 | * +8: dword: йuantity blocks for reading |
||
2770 | * +12 = +0xC: dword: pointer on the buffer, where the data will be written |
||
2771 | * +16 = +0x10: dword: pointer on the buffer for system operation |
||
2772 | (4096 bytes) |
||
2773 | * +20 = +0x14: ASCIIZ-name of the file, the rules of creation of names |
||
2774 | are indicated in the common description |
||
2775 | Returned value: |
||
2776 | * eax = 0 - successfully, differently error code of a file system |
||
2777 | * ebx = file size (in bytes) or |
||
2778 | -1=0xffffffff, if the file is not retrieved |
||
2779 | Remarks: |
||
2780 | * Size of block - 512 bytes. |
||
2781 | * This function is obsolete, for reading files use subfunction 0 |
||
2782 | functions 70, for reading folders - subfunction of 1 function 70. |
||
2783 | * Function allows to read contents of a folder. From file systems is |
||
2784 | supported only FAT. The format of a FAT-folder is described in any |
||
2785 | documentation on FAT. |
||
2786 | * Size of a folder is defined on a size of a chain of clusters in FAT. |
||
2787 | * If the file was terminated earlier, than last requested block was read, |
||
2788 | the function will read, how many can, then will return eax=6 (EOF). |
||
2789 | * Function allows to read root folders /rd/1, /fd/x, /hd [n] /x, but |
||
2790 | in first two cases the current implementation does not follow the |
||
2791 | installed rules: |
||
2792 | for /rd/1: |
||
2793 | * if 0 blocks for reading are indicated, it is considered, |
||
2794 | that is requested 1; |
||
2795 | * if is requested more than 14 blocks or the initial block is not |
||
2796 | less 14, comes back eax=5 (not found) and ebx =-1; |
||
2797 | * size of the root ramdisk = 14 blocks, 0x1C00=7168 bytes; but comes |
||
2798 | back ebx=0 (except for a case of the previous item); |
||
2799 | * strangely enough, it is possible to read 14 block (there, generally |
||
2800 | speaking, garbage - I remind, the score carries on with 0); |
||
2801 | * if one block with number, not smaller 14 was requested even, |
||
2802 | comes back eax=6 (EOF); differently eax=0. |
||
2803 | for /fd/x: |
||
2804 | * if the initial block is not less 14, comes back eax=5 (not found) |
||
2805 | and ebx=0; |
||
2806 | * by the way speaking, the format FAT12 admits diskettes with a size |
||
2807 | of the root less or more than 14 blocks; |
||
2808 | * checks of length is not done; |
||
2809 | * if it was possible to read given with a diskette, comes back eax=0, |
||
2810 | ebx=0; otherwise eax=10 (access denied), ebx =-1. |
||
2811 | * Function handles reading special folders /, /rd, /fd, /hd [n]; but the |
||
2812 | result does not correspond expected (on operation with usual |
||
2813 | files/folders), does not follow the installed rules, can vary in the |
||
2814 | following versions of a kernel and consequently is not described. |
||
2815 | For obtaining the information about the equipment use subfunction 11 |
||
2816 | functions 18 or read appropriate folders subfunction of 1 function 70. |

3033 | code was written, at system calls to the application the registers eax, |
||
3034 | ebx, ecx (from pushad-structure transmitted as argument to the system |
||
3035 | function) came back only. Now it is corrected, so, probably, it is |
||
3036 | meaningful to return a cluster size in edx, while this function have |
||
3037 | not begun to use |
||
3038 | * Generally still exists subfunction 11 functions 18, returning the |
||
3039 | information on a file system. Under the extended table of a disk |
||
3040 | subsystem it is possible to define a cluster size (there it is stored |
||
3041 | in sectors) and total number of clusters for hard disks. |

3073 | ======== Function 59 - get information on last system calls. ========= |
||
3074 | ====================================================================== |
||
3075 | Get data on all system calls of all processes. |
||
3076 | Parameters: |
||
3077 | * eax = 59 - number of the function |
||
3078 | * ebx = 0 - sole subfunction |
||
3079 | * ecx = pointer on buffer |

||
3096 | Remarks: |
||
3097 | * Function is used only in the application systrace. It is rather difficult |

3098 | to present a situation, in which this application or this function are |
||
3099 | really useful, and all system calls for support of this function are a |
||
3100 | little decelerated (though and not strongly)... |
||
3101 | * In this connection there is a sentence support of this function from |
||
3102 | a kernel to remove absolutely, together with the application systrace. |
||
3103 | * Information on system calls is saved in system ring buffer |
||
3104 | on 0x10 of inputs. |
||
3105 | This function simply copies the indicated size given from the mentioned |
||
3106 | buffer to the indicated address. |
||
3107 | * To what from inputs in the buffer corresponds to last call, it is possible |
||
3108 | to define on value eax, namely, |
||
3109 | input (eax and 0xF) (on offset (eax and 0xF) *0x40). |
||
3110 | * In current implementation the seldom meeting problems of |
||
3111 | unsynchronization are possible, when about some calls the |
||
3112 | information becomes outdated. |
||
3113 | * Under the system buffer the page, 4 KB is allocated. |
||
3114 | Size of an input = 64 bytes. |
||
3115 | Why 16 inputs - not clearly are used only. |
||
3116 | * Value esp at moment of system call by this function cannot be found out. |
||
3117 | * Checks of a correctness edx in current implementation is not done. |

||
3120 | =========== Function 60 - Inter Process Communication (IPC). ========== |
||
3121 | ====================================================================== |
||
3122 | IPC is applied to sendings the messages from one process / thread to another. |

3123 | Thus it is necessary previously to agree how to interpreted |
||
3124 | the concrete message. |
||
3125 | |||
3126 | -------- Subfunction 1 - install area for obtaining IPC --------- |
||
3127 | Is called by the process - receiver. |

3149 | --------------- Subfunction 2 - transmit message IPC. ---------------- |
||
3150 | Is called by the process - initiator. |
||
3151 | Parameters: |
||
3152 | * eax = 60 - number of the function |

3161 | which is necessary) |
||
3162 | * eax = 2 - receiver has blocked the IPC-buffer; try slightly to wait |
||
3163 | * eax = 3 - overflow of IPC-buffer of receiver |
||
3164 | * eax = 4 - process/thread with such PID does not exist |
||
3165 | Remarks: |
||
3166 | * System at once after writing the IPC-message in the buffer dispatches |
||
3167 | to stream - receiver event with the code 7 (see codes of events). |

||
3170 | ==== Function 61 - get parameters for direct access to a graphics. === |
||
3171 | ====================================================================== |
||
3172 | Data of graphics screen are accessible to program (area of memory, which purely |
||
3173 | also displays contents of screen) directly without calls of system functions |
||
3174 | through the selector gs: |
||
3175 | mov eax, [gs:0] |
||
3176 | will place in eax first dword of buffer containing information on colour |
||
3177 | of left upper point (and, probably, colour of several following). |
||
3178 | mov [gs:0], eax |
||
3179 | by operation in modes VESA c LFB will install colour of left upper point |
||
3180 | (and, probably, colour of several following). |
||
3181 | Interpretations given of the graphics screen need knowledge of some parameters, |
||
3182 | which come back by this function. |
||
3183 | Remarks: |
||
3184 | * Parameters of a graphics very seldom vary at system operation, namely, |
||
3185 | only in cases, when the user works with the program VRR. |
||
3186 | * At change of videomode the system redraw all windows |
||
3187 | (event with the code 1) and redraw a background (event 5). |
||
3188 | Same events occur and in other cases, which meet much more often, |
||
3189 | than change of videomode. |
||
3190 | * By operation in videomodes with LFB the selector gs specifies on purely |
||
3191 | LFB, so reading / writing on gs result directly in change of contents of |
||
3192 | the screen. By operation in videomodes without LFB gs specifies some area |
||
3193 | of the given kernel, and all functions of output on the screen honesty |
||
3194 | fulfil double operation on writing directly on the screen and on |
||
3195 | writing in this buffer. In result at reading contents of this buffer the |
||
3196 | results correspond to contents of the screen (with, generally speaking, |
||
3197 | large colour permission), and writing ignored. |
||
3198 | Exception is the mode 320*200, for which in main loop system thread the |
||
3199 | upgrade of the screen is fulfilled according to movements |
||
3200 | of a mouse pointer. |

3333 | ============== Function 63 - work with debugging board. ============== |
||
3334 | ====================================================================== |
||
3335 | Debugging board represents the system buffer (on 512 bytes), in which any |
||
3336 | program can write (generally speaking, arbitrary) data and from which other |
||
3337 | program can these data read. |
||
3338 | There is an agreement, according to which written given - text strings |
||
3339 | interpreted as of the debug message on a course of execution of the program. |
||
3340 | The kernel in the defined situations also writes to board of debugging of the |
||
3341 | item of information about execution of some functions; under the agreement of |
||
3342 | the message of a kernel start with the prefix " K: ". |
||
3343 | For review of board of debugging the application board is created which reads |
||
3344 | out the data from the buffer and displays them in the window. board understands |
||
3345 | a sequence of codes 13,10 as transition on new string |
||
3346 | Character with the zero code at the end of string is not mandatory, |
||
3347 | but also does not prevent. |
||
3348 | As has appeared of the debugger necessity of board of debugging a little has |
||
3349 | decreased, as the debugger allows completely to inspect a course of execution |
||
3350 | of the program, and for this purpose it is not required of any efforts on the |
||
3351 | part of the program. Nevertheless in many cases the board of debugging |
||
3352 | continues to remain useful. |
||
3353 | |||

||
3363 | At overflow of the buffer all obtained data are lost also filling |
||
3364 | starts again with zero. |
||
3365 | * For output to board of debugging of more complex objects (strings, numbers) |
||
3366 | this function called in cycle suffices. It is possible to not write |
||
3367 | manually appropriate code, and to take advantage of the file debug.inc, |

4189 | * eax < 0 - has taken place error, |
||
4190 | -eax contains an error code of a file system |
||
4191 | * ebx fail |
||
4192 | Remarks: |
||
4193 | * Command line should be ended by the character with the code 0 |
||
4194 | (ASCIIZ-strings); it are taken into account or all characters up to |
||
4195 | completing zero inclusively, or the first 256 characters, that are less. |
||
4196 | * If the process is started as debugged, it creates in the frozen status; |

4200 | =========== Function 71, subfunction 1 - set window caption ========== |
||
4201 | ====================================================================== |
||
4202 | Parameters: |
||
4203 | * eax = 71 - function number |
||
4204 | * ebx = 1 - subfunction number |
||
4205 | * eбx = caption string address |
||
4206 | Returned value: |
||
4207 | * eax = 0 - caption changed successfully |
||
4208 | * eax = 1 - error occured |
||
4209 | Remarks: |
||
4210 | * String should be in ASCIIZ format. Disregarding real string length, |
||
4211 | no more than 255 chars will be wrawn. |
||
4212 | * Pass NULL in ecx to remove caption |
||
4213 | |||
4214 | ====================================================================== |
||
4215 | ========== Function -1 - complete execution of thread/proces ========= |
||
4216 | ====================================================================== |
||
4217 | Parameters: |
||
4218 | * eax = -1 - number of the function |
||
4219 | Returned value: |
||
4220 | * function does not return neither value, nor handle |
||
4221 | Remarks: |
||
4222 | * If the process obviously did not create streams, it has only one thread, |
||
4223 | which completion results in completion of the process. |
||
4224 | * If current thread - last in process, its completion also results |
||
4225 | in completion of the process. |
||
4226 | * This function completes current thread. Another thread |
||
4227 | is possible kill by call subfunction 2 functions 18. |
||

4229 | ====================================================================== |
||
4230 | =========================== List of events =========================== |
||
4231 | ====================================================================== |
||
4232 | Next event is possible get by call of one from functions 10 (to expect event), |
||
4233 | 11 (to check up without waiting), 23 (to expect during the given time). |
||
4234 | These functions return only those events, which enter into a mask installed by |
||
4235 | the function 40. By default it is first three, that there is enough for of many |
||
4236 | applications of. |
||
4237 | Codes of events: |
||
4238 | * 1 = message about redraw (is reset at function call 0) |
||
4239 | * 2 = key on keyboard is pressed (acts, only when the window is active) |
||
4240 | or "hotkey" is pressed; is reset, when all keys from the buffer are read |
||
4241 | out by the function 2 |
||
4242 | * 3 = button is pressed, defined earlier by function 8(or buttons of closing, |
||
4243 | created implicitly by function 0 is pressed; the button of minimization is |
||
4244 | handled by the system and about it of the message does not come; acts, only |
||
4245 | when the window is active; is reset, when all buttons from the buffer are |
||
4246 | read out by the function 17) |
||
4247 | * 4 = reserved (in current implementation never comes even at unmasking |
||
4248 | by the function 40) |
||
4249 | * 5 = redraw the background of a desktop (is reset automatically after |
||
4250 | redraw, so if in time redraw of a background the program does not wait |
||
4251 | and does not check event, this event it will not remark) |
||
4252 | * 6 = event from the mouse (something happened - pressing a mouse button |
||
4253 | or moving; is reset at reading) |
||
4254 | * 7 = there was an event IPC (look the function 60 - Inter Process |
||
4255 | Communication; is reset at reading) |
||
4256 | * 8 = there was a network event (is reset at reading; look operation |
||
4257 | with the network) |
||
4258 | * 9 = there was a debug event (is reset at reading; look a debug subsystem) |
||
4259 | * 16..31 = there was an event with appropriate IRQ |
||
4260 | (16=IRQ0, 31=IRQ15) (is reset at reading all data IRQ) |
||
4261 | |||
4262 | ====================================================================== |
||
4263 | ==================== Error codes of a file system ==================== |
||
4264 | ====================================================================== |
||
4265 | * 0 = successfully |
||
4266 | * 1 = base and/or partition of the hard disk is not defined |
||
4267 | (subfunctions 7, 8 functions 21) |
||
4268 | * 2 = function is not supported for of the given file system |
||
4269 | (comes back in case of attempt of LBA-reading at prohibited LBA) |
||
4270 | * 3 = Unknown file system |
||
4271 | * 4 = comes back only by function rename by transmission of the strongly |
||
4272 | incorrect parameter and in any way does not correspond to the description |
||
4273 | in sources of a kernel " partition not defined at hd " |
||
4274 | * 5 = file is not retrieved |
||
4275 | * 6 = file was completed |
||
4276 | * 7 = pointer outside of memory of the application |
||
4277 | * 8 = disk is filled |
||
4278 | * 9 = table FAT is destroyed |
||
4279 | * 10 = access denied |
||
4280 | * 11 = error of the device |
||
4281 | At start of the program the following error codes are possible also: |
||
4282 | * 30 = 0x1E = not enough of memory |
||
4283 | * 31 = 0x1F = file is not application |
||
4284 | * 32 = 0x20 = too much processes>>>=4>=n<=4>=39. |
