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

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

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

||
237 | Remarks: |
||
118 | diamond | 238 | * Passing ebx=0 does not transfer control to the next process |
239 | and does not make any operations at all. If it is really required |
||
240 | to transfer control to the next process (to complete a current |
||
241 | time slice), use subfunction 1 of function 68. |

118 | diamond | 278 | * Sizes of the button must be more than 0 and less than 0x8000. |
131 | diamond | 279 | * For skinned windows definition of the window |
118 | diamond | 280 | (call of 0th function) creates two standard buttons - |
281 | for close of the window with identifier 1 and |
||
282 | for minimize of the window with identifier 0xffff. |
||
283 | * The creation of two buttons with same identifiers is admitted. |
||
284 | * The button with the identifier 0xffff at pressing is interpreted |
||
285 | by the system as the button of minimization, the system handles |
||
286 | such pressing independently, not accessing to the application. |
||
287 | In rest it is usual button. |
||
288 | * Total number of buttons for all applications is limited to 4095. |

118 | diamond | 341 | * Slots are numbered starting from 1. |
342 | * Returned value is not a total number of threads, because there |
||
343 | can be free slots. |
||
344 | * When process is starting, system automatically creates |

345 | execution thread. |
||
346 | * Function gives information on the thread. Each process has |
||
347 | at least one thread. One process can create many threads, |
||
348 | in this case each thread has its own slot and the fields |
||
349 | +10, +22, +26 in these slots coincide. |
||
350 | Applications have no common way to define whether two threads |
||
114 | mikedld | 351 | belong to one process. |
118 | diamond | 352 | * The active window - window on top of the window stack - |
353 | receives the messages on a keyboard input. For such window |
||
354 | the position in the window stack coincides with returned value. |
||
355 | * Slot 1 corresponds to special system thread, for which: |
||
356 | * the window is in the bottom of the window stack, the fields |
||
357 | +4 and +6 contain value 1 |
||
358 | * name of the process - "OS/IDLE" (supplemented by spaces) |
||
359 | * address of the process in memory is 0, size of used memory is |
||
114 | mikedld | 360 | 16 Mb (0x1000000) |
361 | * PID=1 |
||
142 | diamond | 362 | * coordinates and sizes of the window and the client area are by |
363 | convention set to 0 |
||
118 | diamond | 364 | * status of the slot is always 0 (running) |
365 | * the execution time adds of time leaving on operations itself |
||
366 | and idle time in waiting for interrupt (which can be got by call |
||
367 | to subfunction 4 of function 18). |
||
368 | * Beginning from slot 2, the normal applications are placed. |
||
1662 | Nasarus | 369 | * The normal applications are placed in memory at the address |
370 | |||
118 | diamond | 371 | There is no intersection, as each process has its own page table. |
372 | * At creation of the thread it is assigned the slot |
||
373 | in the system table and identifier (Process/Thread IDentifier = |
||
374 | PID/TID), which do not vary with time for given thread. |
||
375 | After completion of the thread its slot can be anew used |
||
376 | for another thread. The thread identifier can not be assigned |
||
377 | to other thread even after completion of this thread. |
||
378 | Identifiers, assigned to new threads, grow monotonously. |
||
379 | * If the thread has not yet defined the window by call to |
||
380 | function 0, the position and the sizes |
||
381 | of its window are considered to be zero. |
||
142 | diamond | 382 | * Coordinates of the client area are relative to the window. |
118 | diamond | 383 | * At the moment only the part of the buffer by a size |
4264 | 0CodErr | 384 | 76 = 0x4C bytes is used. Nevertheless it is recommended to use |
118 | diamond | 385 | 1-Kb buffer for the future compatibility, in the future |
386 | some fields can be added. |

1293 | (day of week can be calculated by date). |
||
1294 | * Alarm clock can be set on operation in the given time every day. |
||
1295 | But there is no existing system function to disable it. |
||
1296 | * Operation of alarm clock consists in generation IRQ8. |
||
1297 | * Generally CMOS supports for alarm clock set of value 0xFF |
||
1298 | as one of parameters and it means that the appropriate parameter |
||
1299 | is ignored. But current implementation does not allow this |
||
1300 | (will return 1). |
||
1301 | * Alarm clock is a global system resource; the set of |

1865 | * limit for the total number of reserved areas is exceeded |
||
1866 | (maximum 255 are allowed); |
||
1867 | * the selected range intersects with any of earlier reserved |
||
1868 | * For ports free: an error is an attempt to free range, |
||
1869 | that was not earlier reserved by this function |
||
1870 | (with same ecx,edx). |
||
1871 | * If an error occurs (for both cases) function performs no action. |
||
277 | diamond | 1872 | * At booting the system reserves for itself ports |

118 | diamond | 2172 | =================== Function 50 - set window shape. ================== |
114 | mikedld | 2173 | ====================================================================== |
118 | diamond | 2174 | Normal windows have rectangular shape. This function can give to |
2175 | a window any shape. The shape is given by a set of points inside |
||
2176 | the base rectangle belonging to a window. Position and coordinates |
||
2177 | of the base rectangle are set by function 0 |
||
2178 | and changed by function 67. |
||

118 | diamond | 2180 | --------------------------- Set shape data --------------------------- |
114 | mikedld | 2181 | Parameters: |
118 | diamond | 2182 | * eax = 50 - function number |
2183 | * ebx = 0 - subfunction number |
||

114 | mikedld | 2185 | Returned value: |
2186 | * function does not return value |
||
2187 | |||
118 | diamond | 2188 | -------------------------- Set shape scale --------------------------- |
114 | mikedld | 2189 | Parameters: |
118 | diamond | 2190 | * eax = 50 - function number |
2191 | * ebx = 1 - subfunction number |
||
2192 | * ecx sets a scale: each byte of data defines |
||
2193 | (2^scale)*(2^scale) pixels |
||
114 | mikedld | 2194 | Returned value: |
2195 | * function does not return value |
||
2196 | Remarks: |
||
118 | diamond | 2197 | * Default scale is 0 (scale factor is 1). If in the shape data |
2198 | one byte corresponds to one pixel, there is no necessity |
||
2199 | to set scale. |
||
2200 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2201 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2202 | functions 0, 67. |
118 | diamond | 2203 | * On definition of scale xsize and ysize must be divisible |
2204 | on 2^scale. |
||
2205 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2206 | to a window of square with the side 2^scale (if scale=0, |
||
2207 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2208 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2209 | * Data size: (xsize shr scale)*(ysize shr scale). |
2210 | * Data must be presented in the memory and not change |
||
2211 | after set of shape. |
||
2212 | * The system views the shape data at every window redraw by |
||
2213 | function 0. |
||
2214 | * The call of subfunction 0 with NULL pointer results in return |
||
2215 | to the rectangular shape. |

118 | diamond | 2346 | ========== Function 60 - Inter Process Communication (IPC). ========== |
114 | mikedld | 2347 | ====================================================================== |
118 | diamond | 2348 | IPC is used for message dispatching from one process/thread to |
2349 | another. Previously it is necessary to agree how to interpret |
||
114 | mikedld | 2350 | the concrete message. |
2351 | |||
118 | diamond | 2352 | ----------- Subfunction 1 - set the area for IPC receiving ----------- |
2353 | Is called by process-receiver. |

2364 | buffer data are not changed from outside (no new messages) |
||
114 | mikedld | 2365 | * +4: dword: occupied place in the buffer (in bytes) |
2366 | * +8: first message |
||
2367 | * +8+n: second message |
||
2368 | * ... |
||
118 | diamond | 2369 | Format of a message: |

118 | diamond | 2380 | * edx = pointer to the message data |
2381 | * esi = message length (in bytes) |
||
114 | mikedld | 2382 | Returned value: |
118 | diamond | 2383 | * eax = 0 - success |
2384 | * eax = 1 - the receiver has not defined buffer for IPC messages |
||
2385 | (can be, still have no time, |
||
2386 | and can be, this is not right process) |
||
2387 | * eax = 2 - the receiver has blocked IPC-buffer; try to wait a bit |
||
2388 | * eax = 3 - overflow of IPC-buffer of the receiver |

||
118 | diamond | 2395 | ==== Function 61 - get parameters for the direct graphics access. ==== |
114 | mikedld | 2396 | ====================================================================== |
118 | diamond | 2397 | The data of the graphics screen (the memory area which displays |
2398 | screen contents) are accessible to a program directly, without |
||
2399 | any system calls, through the selector gs: |
||
5871 | hidnplayr | 2400 | mov eax, [gs:0] |
118 | diamond | 2401 | places in eax the first dword of the buffer, which contains |
2402 | information on color of the left upper point (and, possibly, colors |
||
2403 | of several following). |
||
5871 | hidnplayr | 2404 | mov [gs:0], eax |
118 | diamond | 2405 | by work in VESA modes with LFB sets color of the left upper point |
2406 | (and, possibly, colors of several following). |
||
2407 | To interpret the data of graphics screen program needs to know |
||
2408 | some parameters, returning by this function. |
||
114 | mikedld | 2409 | Remarks: |
118 | diamond | 2410 | * Graphics parameters changes very seldom at work, |
2411 | namely, only in cases, when user works with the application VRR. |
||
2412 | * At videomode change the system redraws all windows (event |
||
2413 | with code 1) and redraws the background (event 5). |
||
2414 | Same events occur in other cases too, which meet much more often, |
||
2415 | than videomode change. |
||
2416 | * By operation in videomodes with LFB the selector gs points to |
||
2417 | LFB itself, so reading/writing on gs result directly in |
||
2418 | change of screen contents. By operation in videomodes without |
||
2419 | LFB gs points to some data area in the kernel, and all functions |
||
2420 | of screen output fulfil honesty double operation on writing |
||
2421 | directly to the screen and writing to this buffer. In result |
||
2422 | at reading contents of this buffer the results correspond to |
||
2423 | screen contents (with, generally speaking, large color |
||
2424 | resolution), and writing is ignored. |
||
2425 | One exception is the mode 320*200, for which main loop of the |
||
2426 | system thread updates the screen according to mouse movements. |

118 | diamond | 2563 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 2564 | ====================================================================== |
118 | diamond | 2565 | The debug board is the global system buffer (with the size |
499 | diamond | 2566 | 1024 bytes), to which any program can write (generally speaking, |
118 | diamond | 2567 | arbitrary) data and from which other program can read these data. |
2568 | By the agreement written data are text strings interpreted as |
||
2569 | debug messages on a course of program execution. The kernel in |
||
2570 | some situations also writes to the debug board information on |
||
2571 | execution of some functions; by the agreement kernel messages |
||
2572 | begins from the prefix "K : ". |
||
2573 | For view of the debug board the application 'board' was created, |
||
2574 | which reads data from the buffer and displays them in its window. |
||
2575 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
2576 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 2577 | but also does not prevent. |
118 | diamond | 2578 | Because debugger has been written, the value of the debug board |
2579 | has decreased, as debugger allows to inspect completely a course of |
||
2580 | program execution without any efforts from the direction of program |
||
2581 | itself. Nevertheless in some cases the debug board is still useful. |
||
114 | mikedld | 2582 | |
118 | diamond | 2583 | ----------------------------- Write byte ----------------------------- |
114 | mikedld | 2584 | Parameters: |

114 | mikedld | 2588 | Returned value: |
2589 | * function does not return value |
||
2590 | Remarks: |
||
118 | diamond | 2591 | * Byte is written to the buffer. Buffer size is 512 bytes. |
2592 | At buffer overflow all obtained data are lost. |
||
2593 | * For output to the debug board of more complicated objects |
||
2594 | (strings, numbers) it is enough to call this function in cycle. |
||
2595 | It is possible not to write the appropriate code manually and use |
||
2596 | file 'debug.inc', which is included into the distributive. |
||
114 | mikedld | 2597 | |

114 | mikedld | 2617 | Remarks: |
193 | diamond | 2618 | * There is another way to dynamically allocate/free memory - |
2619 | subfunctions 11, 12, 13 of function 68. |
||
2620 | * The function cannot be used together with 68.11, 68.12, 68.13. |

||
114 | mikedld | 2733 | Remarks: |
118 | diamond | 2734 | * Hotkey can work either at pressing or at release. Release |
2735 | scancode of a key is more on 128 than pressing scancode |
||
2736 | (i.e. high bit is set). |
||
2737 | * Several applications can set the same combination; |
||
2738 | all such applications will be informed on pressing |

||
2790 | * Previously the window must be defined by function 0. |
||
114 | mikedld | 2791 | It sets initial coordinates and sizes of the window. |
118 | diamond | 2792 | * Sizes of the window are understood in sense of function 0, |
2793 | that is one pixel less than real sizes. |
||
2794 | * The function call for maximized windows is simply ignored. |
||
2795 | * For windows of appropriate styles position and/or sizes can be |
||
2796 | changed by user; current position and sizes can be obtained by |

114 | mikedld | 2871 | ====================================================================== |
118 | diamond | 2872 | MSR = Model Specific Register; the complete list of MSR-registers |
2873 | of a processor is included to the documentation on it (for example, |
||
2874 | IA-32 Intel Architecture Software Developer's Manual, |
||
2875 | Volume 3, Appendix B); each processor family has its own subset |
||
2876 | of the MSR-registers. |

2885 | Remarks: |
||
118 | diamond | 2886 | * If ecx contains nonexistent or not implemented for this processor |
2887 | MSR, processor will generate an exception in the kernel, which |
||
2888 | will kill the thread. |
||
2889 | * Previously it is necessary to check, whether MSRs are supported |
||
2890 | as a whole, with the instruction 'cpuid'. Otherwise processor |
||
2891 | will generate other exception in the kernel, which will anyway |
||
2892 | kill the thread. |

||
3100 | ======== Function 68, subfunction 24 - set exception handler. ======== |

3101 | ====================================================================== |
||
3102 | Parameters: |
||
3103 | * eax = 68 - function number |
||
1077 | Galkov | 3104 | * ebx = 24 - subfunction number |
3105 | * ecx = address of the new exception handler |
||
1662 | Nasarus | 3106 | * edx = the mask of handled exceptions |
1077 | Galkov | 3107 | Returned value: |
3108 | * eax = address of the old exception handler (0, if it was not set) |
||
1662 | Nasarus | 3109 | * ebx = the old mask of handled exceptions |
1077 | Galkov | 3110 | Remarks: |
1662 | Nasarus | 3111 | * Bit number in mask of exceptions corresponds to exception number |
3112 | in CPU-specification (Intel-PC). For example, FPU exceptions have |
||
3113 | number 16 (#MF), and SSE exceptions - 19 (#XF). |
||
3114 | * The current implementation ignores the inquiry for hook of 7 |
||
3115 | exception - the system handles #NM by its own. |
||
3116 | * The exception handler is called with exception number as first |
||
3117 | (and only) stack parameter. So, correct exit from the handler is |
||
3118 | RET 4. It returns to the instruction, that caused the exception, |
||
3119 | for faults, and to the next instruction for traps (see |
||
3120 | classification of exceptions in CPU specification). |
||
3121 | * When user handler receives control, the corresponding bit in |
||
3122 | the exception mask is cleared. Raising this exception |
||
3123 | in consequence leads to default handling, that is, |
||
3124 | terminating the application in absence of debugger or |
||
3125 | suspend with notification of debugger otherwise. |
||
3126 | * After user handler completes critical operations, it can set |
||
3127 | the corresponding bit in the exception mask with subfunction 25. |
||
3128 | Also user handler is responsible for clearing exceptions flags in |
||
3129 | FPU and/or SSE. |
