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 |
||

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. |
||

182 | Parameters: |
||
118 | diamond | 183 | * eax = 3 - function number |
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. |
||

219 | * function does not return value |
||
220 | Remarks: |
||
5682 | leency | 221 | * You can not use B=1 and C=1 at the same time, since both use edi. |
5848 | pathoswith | 222 | * When SSS=0, font may be smoothed, depending on system setting. |
223 | * User buffer structure: |
||
224 | Xsize dd |

236 | * function does not return value |
||
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. |
||
114 | mikedld | 242 | |
243 | ====================================================================== |
||
118 | diamond | 244 | ============== Function 6 - read the file from ramdisk. ============== |

259 | to fulfil the same operations with the extended possibilities. |
||
114 | mikedld | 260 | * Block = 512 bytes. |
118 | diamond | 261 | * For reading all file you can specify the certainly large value |
262 | in edx, for example, edx = -1; but in this case be ready that |
||
263 | the program will "fall", if the file will appear too large and can |
||
264 | not be placed in the program memory. |
||
265 | * The filename must be either in the format 8+3 characters |
||
266 | (first 8 characters - name itself, last 3 - extension, |

||
270 | supplemented if necessary by spaces). |
||
271 | The filename must be written with capital letters. The terminating |
||
272 | character with code 0 is not necessary (not ASCIIZ-string). |
||
273 | * This function does not support folders on the ramdisk. |

313 | for close of the window with identifier 1 and |
||
314 | for minimize of the window with identifier 0xffff. |
||
315 | * The creation of two buttons with same identifiers is admitted. |
||
316 | * The button with the identifier 0xffff at pressing is interpreted |
||
317 | by the system as the button of minimization, the system handles |
||
318 | such pressing independently, not accessing to the application. |
||
319 | In rest it is usual button. |
||
320 | * Total number of buttons for all applications is limited to 4095. |

1662 | Nasarus | 401 | * The normal applications are placed in memory at the address |
402 | |||
118 | diamond | 403 | There is no intersection, as each process has its own page table. |
404 | * At creation of the thread it is assigned the slot |

405 | in the system table and identifier (Process/Thread IDentifier = |
||
406 | PID/TID), which do not vary with time for given thread. |
||
407 | After completion of the thread its slot can be anew used |
||
408 | for another thread. The thread identifier can not be assigned |
||
409 | to other thread even after completion of this thread. |

410 | Identifiers, assigned to new threads, grow monotonously. |

142 | diamond | 414 | * Coordinates of the client area are relative to the window. |
118 | diamond | 415 | * At the moment only the part of the buffer by a size |
4264 | 0CodErr | 416 | 76 = 0x4C bytes is used. Nevertheless it is recommended to use |
118 | diamond | 417 | 1-Kb buffer for the future compatibility, in the future |
418 | some fields can be added. |

1325 | (day of week can be calculated by date). |
||
1326 | * Alarm clock can be set on operation in the given time every day. |
||
1327 | But there is no existing system function to disable it. |
||
1328 | * Operation of alarm clock consists in generation IRQ8. |
||
1329 | * Generally CMOS supports for alarm clock set of value 0xFF |
||
1330 | as one of parameters and it means that the appropriate parameter |
||
1331 | is ignored. But current implementation does not allow this |
||
1332 | (will return 1). |
||
1333 | * Alarm clock is a global system resource; the set of |

1841 | keys and buttons. This is enough for many applications. |
||
1842 | * Events prohibited in the mask are saved anyway, when come; |
||
1843 | they are simply not informed with event functions. |
||
1844 | * Event functions take into account the mask on moment of |
||
1845 | function call, not on moment of event arrival. |

1897 | * limit for the total number of reserved areas is exceeded |
||
1898 | (maximum 255 are allowed); |
||
1899 | * the selected range intersects with any of earlier reserved |
||
1900 | * For ports free: an error is an attempt to free range, |
||
1901 | that was not earlier reserved by this function |
||
1902 | (with same ecx,edx). |
||
1903 | * If an error occurs (for both cases) function performs no action. |

118 | diamond | 2204 | =================== Function 50 - set window shape. ================== |
114 | mikedld | 2205 | ====================================================================== |
118 | diamond | 2206 | Normal windows have rectangular shape. This function can give to |
2207 | a window any shape. The shape is given by a set of points inside |
||
2208 | the base rectangle belonging to a window. Position and coordinates |
||
2209 | of the base rectangle are set by function 0 |
||
2210 | and changed by function 67. |
||

118 | diamond | 2220 | -------------------------- Set shape scale --------------------------- |
114 | mikedld | 2221 | Parameters: |
118 | diamond | 2222 | * eax = 50 - function number |
2223 | * ebx = 1 - subfunction number |
||
2224 | * ecx sets a scale: each byte of data defines |
||
2225 | (2^scale)*(2^scale) pixels |
||
114 | mikedld | 2226 | Returned value: |
2227 | * function does not return value |
||
2228 | Remarks: |
||
118 | diamond | 2229 | * Default scale is 0 (scale factor is 1). If in the shape data |
2230 | one byte corresponds to one pixel, there is no necessity |
||
2231 | to set scale. |
||
2232 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2233 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2234 | functions 0, 67. |
118 | diamond | 2235 | * On definition of scale xsize and ysize must be divisible |
2236 | on 2^scale. |
||
2237 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2238 | to a window of square with the side 2^scale (if scale=0, |
||
2239 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2240 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2241 | * Data size: (xsize shr scale)*(ysize shr scale). |
2242 | * Data must be presented in the memory and not change |
||
2243 | after set of shape. |
||
2244 | * The system views the shape data at every window redraw by |
||
2245 | function 0. |
||
2246 | * The call of subfunction 0 with NULL pointer results in return |
||
2247 | to the rectangular shape. |

118 | diamond | 2378 | ========== Function 60 - Inter Process Communication (IPC). ========== |
114 | mikedld | 2379 | ====================================================================== |
118 | diamond | 2380 | IPC is used for message dispatching from one process/thread to |
2381 | another. Previously it is necessary to agree how to interpret |
||
114 | mikedld | 2382 | the concrete message. |
2383 | |||
118 | diamond | 2384 | ----------- Subfunction 1 - set the area for IPC receiving ----------- |
2385 | Is called by process-receiver. |

2396 | buffer data are not changed from outside (no new messages) |
||
114 | mikedld | 2397 | * +4: dword: occupied place in the buffer (in bytes) |
2398 | * +8: first message |
||
2399 | * +8+n: second message |
||
2400 | * ... |
||
118 | diamond | 2401 | Format of a message: |

118 | diamond | 2412 | * edx = pointer to the message data |
2413 | * esi = message length (in bytes) |
||
114 | mikedld | 2414 | Returned value: |
118 | diamond | 2415 | * eax = 0 - success |
2416 | * eax = 1 - the receiver has not defined buffer for IPC messages |
||
2417 | (can be, still have no time, |
||
2418 | and can be, this is not right process) |
||
2419 | * eax = 2 - the receiver has blocked IPC-buffer; try to wait a bit |
||
2420 | * eax = 3 - overflow of IPC-buffer of the receiver |
||
114 | mikedld | 2421 | * eax = 4 - process/thread with such PID does not exist |
2422 | Remarks: |

||
118 | diamond | 2427 | ==== Function 61 - get parameters for the direct graphics access. ==== |
114 | mikedld | 2428 | ====================================================================== |
118 | diamond | 2429 | The data of the graphics screen (the memory area which displays |
2430 | screen contents) are accessible to a program directly, without |
||
2431 | any system calls, through the selector gs: |
||
5871 | hidnplayr | 2432 | mov eax, [gs:0] |
118 | diamond | 2433 | places in eax the first dword of the buffer, which contains |
2434 | information on color of the left upper point (and, possibly, colors |
||
2435 | of several following). |
||
5871 | hidnplayr | 2436 | mov [gs:0], eax |
118 | diamond | 2437 | by work in VESA modes with LFB sets color of the left upper point |
2438 | (and, possibly, colors of several following). |
||
2439 | To interpret the data of graphics screen program needs to know |
||
2440 | some parameters, returning by this function. |
||
114 | mikedld | 2441 | Remarks: |
118 | diamond | 2442 | * Graphics parameters changes very seldom at work, |
2443 | namely, only in cases, when user works with the application VRR. |
||
2444 | * At videomode change the system redraws all windows (event |
||
2445 | with code 1) and redraws the background (event 5). |
||
2446 | Same events occur in other cases too, which meet much more often, |
||
2447 | than videomode change. |
||
2448 | * By operation in videomodes with LFB the selector gs points to |
||
2449 | LFB itself, so reading/writing on gs result directly in |
||
2450 | change of screen contents. By operation in videomodes without |
||
2451 | LFB gs points to some data area in the kernel, and all functions |
||
2452 | of screen output fulfil honesty double operation on writing |
||
2453 | directly to the screen and writing to this buffer. In result |
||
2454 | at reading contents of this buffer the results correspond to |
||
2455 | screen contents (with, generally speaking, large color |
||
2456 | resolution), and writing is ignored. |
||
2457 | One exception is the mode 320*200, for which main loop of the |
||
2458 | system thread updates the screen according to mouse movements. |
||

118 | diamond | 2595 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 2596 | ====================================================================== |
118 | diamond | 2597 | The debug board is the global system buffer (with the size |
499 | diamond | 2598 | 1024 bytes), to which any program can write (generally speaking, |
118 | diamond | 2599 | arbitrary) data and from which other program can read these data. |
2600 | By the agreement written data are text strings interpreted as |
||
2601 | debug messages on a course of program execution. The kernel in |
||
2602 | some situations also writes to the debug board information on |
||
2603 | execution of some functions; by the agreement kernel messages |
||
2604 | begins from the prefix "K : ". |
||
2605 | For view of the debug board the application 'board' was created, |
||
2606 | which reads data from the buffer and displays them in its window. |
||
2607 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
2608 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 2609 | but also does not prevent. |
118 | diamond | 2610 | Because debugger has been written, the value of the debug board |
2611 | has decreased, as debugger allows to inspect completely a course of |
||
2612 | program execution without any efforts from the direction of program |
||
2613 | itself. Nevertheless in some cases the debug board is still useful. |
||
114 | mikedld | 2614 | |
118 | diamond | 2615 | ----------------------------- Write byte ----------------------------- |
114 | mikedld | 2616 | Parameters: |
118 | diamond | 2617 | * eax = 63 - function number |
2618 | * ebx = 1 - subfunction number |

2619 | * cl = data byte |
||
114 | mikedld | 2620 | Returned value: |
2621 | * function does not return value |
||
2622 | Remarks: |
||
118 | diamond | 2623 | * Byte is written to the buffer. Buffer size is 512 bytes. |
2624 | At buffer overflow all obtained data are lost. |
||
2625 | * For output to the debug board of more complicated objects |
||
2626 | (strings, numbers) it is enough to call this function in cycle. |
||
2627 | It is possible not to write the appropriate code manually and use |
||
2628 | file 'debug.inc', which is included into the distributive. |
||
114 | mikedld | 2629 | |
118 | diamond | 2630 | ----------------------------- Read byte ------------------------------ |

118 | diamond | 2633 | * eax = 63 - function number |
2634 | * ebx = 2 - subfunction number |
||
114 | mikedld | 2635 | Returned value: |
118 | diamond | 2636 | * eax = ebx = 0 - the buffer is empty |
2637 | * eax = byte, ebx = 1 - byte was successfully read |

2648 | * eax = 1 - not enough memory |
||
114 | mikedld | 2649 | Remarks: |
193 | diamond | 2650 | * There is another way to dynamically allocate/free memory - |
2651 | subfunctions 11, 12, 13 of function 68. |
||
2652 | * The function cannot be used together with 68.11, 68.12, 68.13. |

2767 | scancode of a key is more on 128 than pressing scancode |
||
2768 | (i.e. high bit is set). |
||
2769 | * Several applications can set the same combination; |
||
2770 | all such applications will be informed on pressing |

2822 | * Previously the window must be defined by function 0. |
||
114 | mikedld | 2823 | It sets initial coordinates and sizes of the window. |
118 | diamond | 2824 | * Sizes of the window are understood in sense of function 0, |
2825 | that is one pixel less than real sizes. |
||
2826 | * The function call for maximized windows is simply ignored. |
||
2827 | * For windows of appropriate styles position and/or sizes can be |
||
2828 | changed by user; current position and sizes can be obtained by |

3131 | ====================================================================== |
||
3132 | ======== Function 68, subfunction 24 - set exception handler. ======== |
||
3133 | ====================================================================== |
||
3134 | Parameters: |
||
3135 | * eax = 68 - function number |
||
1077 | Galkov | 3136 | * ebx = 24 - subfunction number |
3137 | * ecx = address of the new exception handler |
||
1662 | Nasarus | 3138 | * edx = the mask of handled exceptions |
1077 | Galkov | 3139 | Returned value: |
3140 | * eax = address of the old exception handler (0, if it was not set) |
||
1662 | Nasarus | 3141 | * ebx = the old mask of handled exceptions |
1077 | Galkov | 3142 | Remarks: |
1662 | Nasarus | 3143 | * Bit number in mask of exceptions corresponds to exception number |
3144 | in CPU-specification (Intel-PC). For example, FPU exceptions have |
||
3145 | number 16 (#MF), and SSE exceptions - 19 (#XF). |
||
3146 | * The current implementation ignores the inquiry for hook of 7 |
||
3147 | exception - the system handles #NM by its own. |
||
3148 | * The exception handler is called with exception number as first |
||
3149 | (and only) stack parameter. So, correct exit from the handler is |
||
3150 | RET 4. It returns to the instruction, that caused the exception, |
||
3151 | for faults, and to the next instruction for traps (see |
||
3152 | classification of exceptions in CPU specification). |
||
3153 | * When user handler receives control, the corresponding bit in |
||
3154 | the exception mask is cleared. Raising this exception |
||
3155 | in consequence leads to default handling, that is, |
||
3156 | terminating the application in absence of debugger or |
||
3157 | suspend with notification of debugger otherwise. |
||
3158 | * After user handler completes critical operations, it can set |
||
3159 | the corresponding bit in the exception mask with subfunction 25. |
||
3160 | Also user handler is responsible for clearing exceptions flags in |
||
3161 | FPU and/or SSE. |
