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. |
||
114 | mikedld | 14 | |

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: |
||
118 | diamond | 28 | * Y=1 - only define window area, draw nothing |
131 | diamond | 29 | * Y=3 - skinned window |
641 | diamond | 30 | * Y=4 - skinned fixed-size window |
6473 | pathoswith | 31 | * Y=0,2 window types are outdated and should not be used anymore, |
6171 | leency | 32 | they are retained for compatibility with old programs. |
33 | * other possible values (from 5 to 15) are reserved, |
||
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) |
6168 | leency | 38 | * A = 1 - window has caption |
118 | diamond | 39 | * B = 1 - coordinates of all graphics primitives are relative to |
40 | window client area |
||
303 | mikedld | 41 | * C = 1 - don't fill working area on window draw |
118 | diamond | 42 | * D = 0 - normal filling of the working area, 1 - gradient |
43 | The following parameters are intended for windows |
||
44 | of a type I and II, and ignored for styles Y=1,3: |
||
45 | * esi = 0xXYRRGGBB - color of the header |
||
46 | * RR, GG, BB define color |
||
4051 | heavyiron | 47 | * Y=0 - usual window, Y=1 - unmovable window (works for all window styles) |
6168 | leency | 48 | * X not used, other values of Y are reserved |
49 | * edi = caption string for styles Y=3,4 (also can be set by func 71.1) |
||
114 | mikedld | 50 | Returned value: |
51 | * function does not return value |
||
52 | Remarks: |
||
118 | diamond | 53 | * Position and sizes of the window are installed by the first |
54 | call of this function and are ignored at subsequent; to change |
||
55 | position and/or sizes of already created window use function 67. |
||
641 | diamond | 56 | * For windows with styles Y=3,4 and caption (A=1) caption string |
57 | is set by the first call of this function and is ignored |
||
58 | at subsequent (strictly speaking, is ignored after a call to |
||
59 | subfunction 2 of function 12 - end redraw); to change caption of |
||
60 | already created window use subfunction 1 of function 71. |
||
118 | diamond | 61 | * If the window has appropriate styles, position and/or sizes can be |
62 | changed by user. Current position and sizes can be obtained |
||
63 | by function 9. |
||
64 | * The window must fit on the screen. If the transferred |
||
65 | coordinates and sizes do not satisfy to this condition, |
||
66 | appropriate coordinate (or, probably, both) is considered as zero, |
||
131 | diamond | 67 | and if it does not help too, the appropriate size |
118 | diamond | 68 | (or, probably, both) is installed in a size of the screen. |
2409 | Serge | 69 | |
131 | diamond | 70 | Further let us designate xpos,ypos,xsize,ysize - values passed |
71 | in ebx,ecx. The coordinates are resulted concerning |
||
118 | diamond | 72 | the left upper corner of the window, which, thus, is set as (0,0), |
73 | coordinates of the right lower corner essence (xsize,ysize). |
||
7722 | dunkaist | 74 | * The sizes of the window are understood in sense of coordinates |
118 | diamond | 75 | of the right lower corner. This concerns all other functions too. |
76 | It means, that the real sizes are on 1 pixel more. |
||
77 | * The window of style Y=1 looks as follows: |
||
114 | mikedld | 78 | * completely defined by the application |
6168 | leency | 79 | * The skinned window Y=3,4 looks as follows: |
114 | mikedld | 80 | * draw external frame of width 1 pixel |
118 | diamond | 81 | with color 'outer' from the skin |
82 | * draw intermediate frame of width 3 pixel |
||
83 | with color 'frame' from the skin |
||
84 | * draw internal frame of width 1 pixel |
||
85 | with color 'inner' from the skin |
||
86 | * draw header (on bitmaps from the skin) in a rectangle |
||
114 | mikedld | 87 | (0,0) - (xsize,_skinh-1) |
118 | diamond | 88 | * if ysize>=26, fill the working area of the window - |
89 | rectangle with the left upper corner (5,_skinh) and right lower |
||
90 | (xsize-5,ysize-5) with color indicated in edx |
||
91 | (taking a gradient into account) |
||
133 | diamond | 92 | * define two standard buttons: close and minimize |
114 | mikedld | 93 | (see function 8) |
118 | diamond | 94 | * if A=1 and edi contains (nonzero) pointer to caption string, |
95 | it is drawn in place in header defined in the skin |
||
96 | * value _skinh is accessible as the result of call |
||
97 | subfunction 4 of function 48 |

100 | eax - SF_CREATE_WINDOW (0) |
||
114 | mikedld | 101 | ====================================================================== |
118 | diamond | 102 | ================ Function 1 - put pixel in the window. =============== |
114 | mikedld | 103 | ====================================================================== |
104 | Parameters: |
||
118 | diamond | 105 | * eax = 1 - function number |
106 | * ebx = x-coordinate (relative to the window) |
||
107 | * ecx = y-coordinate (relative to the window) |
||
108 | * edx = 0x00RRGGBB - color of a pixel |
||
109 | edx = 0x01xxxxxx - invert color of a pixel |
||
110 | (low 24 bits are ignored) |
||
114 | mikedld | 111 | Returned value: |
112 | * function does not return value |
||
113 | |||
6057 | IgorA | 114 | ---------------------- Constants for registers: ---------------------- |
115 | eax - SF_PUT_PIXEL (1) |
||
114 | mikedld | 116 | ====================================================================== |
118 | diamond | 117 | ============ Function 2 - get the code of the pressed key. =========== |
114 | mikedld | 118 | ====================================================================== |
119 | Takes away the code of the pressed key from the buffer. |
||
120 | Parameters: |
||
118 | diamond | 121 | * eax = 2 - function number |
114 | mikedld | 122 | Returned value: |
118 | diamond | 123 | * if the buffer is empty, function returns eax=1 |
124 | * if the buffer is not empty, function returns al=0, |
||
4588 | mario79 | 125 | ah=code of the pressed key, |
4612 | mario79 | 126 | bits 16-23 = contain scancode for pressed key in ASCII mode, |
127 | in the scancodes mode this bits cleared. |
||
4588 | mario79 | 128 | bits 23-31 = zero |
118 | diamond | 129 | * if there is "hotkey", function returns al=2, |
130 | ah=scancode of the pressed key (0 for control keys), |
||
131 | high word of eax contains a status of control keys at the moment |
||
132 | of pressing a hotkey |
||
114 | mikedld | 133 | Remarks: |
118 | diamond | 134 | * There is a common system buffer of the pressed keys |
135 | by a size of 120 bytes, organized as queue. |
||
136 | * There is one more common system buffer on 120 "hotkeys". |
||
137 | * If the application with the inactive window calls this function, |
||
138 | the buffer of the pressed keys is considered to be empty. |
||
139 | * By default this function returns ASCII-codes; to switch |
||
140 | to the scancodes mode (and back) use function 66. |
||
141 | However, hotkeys are always notificated as scancodes. |
||
142 | * To find out, what keys correspond to what codes, start |
||
143 | the application keyascii and scancode. |
||
144 | * Scancodes come directly from keyboard and are fixed; |
||
145 | ASCII-codes turn out with usage of the conversion tables, |
||
146 | which can be set by subfunction 2 of function 21 |
||
147 | and get by subfunction 2 of function 26. |
||
148 | * As a consequence, ASCII-codes take into account current |
||
149 | keyboard layout (rus/en) as opposed to scancodes. |
||
150 | * This function notifies only about those hotkeys, which were |
||
151 | defined by this thread by subfunction 4 of function 66. |

118 | diamond | 162 | * each item is BCD-number, for example, |
163 | for time 23:59:59 function returns 0x00595923 |
||
114 | mikedld | 164 | Remarks: |
118 | diamond | 165 | * See also subfunction 9 of function 26 - get time from |
166 | the moment of start of the system; it is more convenient, because |
||
167 | returns simply DWORD-value of the time counter. |
||
168 | * System time can be set by function 22. |

||
217 | Remarks: |
||
118 | diamond | 218 | * Passing ebx=0 does not transfer control to the next process |
219 | and does not make any operations at all. If it is really required |
||
220 | to transfer control to the next process (to complete a current |
||
221 | time slice), use subfunction 1 of function 68. |

||
244 | ====================================================================== |
||
118 | diamond | 245 | Parameters for button definition: |
246 | * eax = 8 - function number |

||
118 | diamond | 251 | * high (31st) bit of edx is cleared |
252 | * if 30th bit of edx is set - do not draw the button |
||
253 | * if 29th bit of edx is set - do not draw a frame |
||
114 | mikedld | 254 | at pressing the button |
118 | diamond | 255 | * esi = 0x00RRGGBB - color of the button |
256 | Parameters for button deleting: |
||
257 | * eax = 8 - function number |
||
114 | mikedld | 258 | * edx = 0x80nnnnnn, where nnnnnn - identifier of the button |

260 | * function does not return value |
||
261 | Remarks: |
||
118 | diamond | 262 | * Sizes of the button must be more than 0 and less than 0x8000. |
131 | diamond | 263 | * For skinned windows definition of the window |
118 | diamond | 264 | (call of 0th function) creates two standard buttons - |
265 | for close of the window with identifier 1 and |
||
266 | for minimize of the window with identifier 0xffff. |
||
267 | * The creation of two buttons with same identifiers is admitted. |
||
268 | * The button with the identifier 0xffff at pressing is interpreted |
||
269 | by the system as the button of minimization, the system handles |
||
270 | such pressing independently, not accessing to the application. |
||
271 | In rest it is usual button. |
||
272 | * Total number of buttons for all applications is limited to 4095. |

114 | mikedld | 329 | Remarks: |
118 | diamond | 330 | * Slots are numbered starting from 1. |
331 | * Returned value is not a total number of threads, because there |
||
332 | can be free slots. |
||
333 | * When process is starting, system automatically creates |
||
334 | execution thread. |
||
335 | * Function gives information on the thread. Each process has |
||
336 | at least one thread. One process can create many threads, |
||
337 | in this case each thread has its own slot and the fields |
||
338 | +10, +22, +26 in these slots coincide. |
||
339 | Applications have no common way to define whether two threads |

118 | diamond | 1431 | * Value of installation of day of week seems to be doubtful, |
1432 | as it a little where is used |
||
1433 | (day of week can be calculated by date). |
||
1434 | * Alarm clock can be set on operation in the given time every day. |
||
1435 | But there is no existing system function to disable it. |
||
1436 | * Operation of alarm clock consists in generation IRQ8. |
||
1437 | * Generally CMOS supports for alarm clock set of value 0xFF |
||
1438 | as one of parameters and it means that the appropriate parameter |
||
1439 | is ignored. But current implementation does not allow this |
||
1440 | (will return 1). |
||
1441 | * Alarm clock is a global system resource; the set of |
||
1442 | an alarm clock cancels automatically the previous set. |
||
1443 | However, at moment no program uses it. |

118 | diamond | 2497 | =================== Function 50 - set window shape. ================== |
114 | mikedld | 2498 | ====================================================================== |
118 | diamond | 2499 | Normal windows have rectangular shape. This function can give to |
2500 | a window any shape. The shape is given by a set of points inside |
||
2501 | the base rectangle belonging to a window. Position and coordinates |
||
2502 | of the base rectangle are set by function 0 |
||
2503 | and changed by function 67. |
||

2512 | |||
118 | diamond | 2513 | -------------------------- Set shape scale --------------------------- |
114 | mikedld | 2514 | Parameters: |
118 | diamond | 2515 | * eax = 50 - function number |
2516 | * ebx = 1 - subfunction number |
||
2517 | * ecx sets a scale: each byte of data defines |
||
2518 | (2^scale)*(2^scale) pixels |
||
114 | mikedld | 2519 | Returned value: |
2520 | * function does not return value |
||
2521 | Remarks: |
||
118 | diamond | 2522 | * Default scale is 0 (scale factor is 1). If in the shape data |
2523 | one byte corresponds to one pixel, there is no necessity |
||
2524 | to set scale. |
||
2525 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2526 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2527 | functions 0, 67. |
118 | diamond | 2528 | * On definition of scale xsize and ysize must be divisible |
2529 | on 2^scale. |
||
2530 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2531 | to a window of square with the side 2^scale (if scale=0, |
||
2532 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2533 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2534 | * Data size: (xsize shr scale)*(ysize shr scale). |
2535 | * Data must be presented in the memory and not change |
||
2536 | after set of shape. |
||
2537 | * The system views the shape data at every window redraw by |
||
2538 | function 0. |
||
2539 | * The call of subfunction 0 with NULL pointer results in return |
||
2540 | to the rectangular shape. |

114 | mikedld | 2749 | ====================================================================== |
118 | diamond | 2750 | The data of the graphics screen (the memory area which displays |
2751 | screen contents) are accessible to a program directly, without |
||
2752 | any system calls, through the selector gs: |
||
5871 | hidnplayr | 2753 | mov eax, [gs:0] |
118 | diamond | 2754 | places in eax the first dword of the buffer, which contains |
2755 | information on color of the left upper point (and, possibly, colors |
||
2756 | of several following). |
||
5871 | hidnplayr | 2757 | mov [gs:0], eax |
118 | diamond | 2758 | by work in VESA modes with LFB sets color of the left upper point |
2759 | (and, possibly, colors of several following). |
||
2760 | To interpret the data of graphics screen program needs to know |
||
2761 | some parameters, returning by this function. |
||
114 | mikedld | 2762 | Remarks: |
7121 | dunkaist | 2763 | * Graphics parameters changes very seldom at work. |
118 | diamond | 2764 | * At videomode change the system redraws all windows (event |
2765 | with code 1) and redraws the background (event 5). |
||
2766 | Same events occur in other cases too, which meet much more often, |
||
2767 | than videomode change. |
||
2768 | * By operation in videomodes with LFB the selector gs points to |
||
2769 | LFB itself, so reading/writing on gs result directly in |
||
2770 | change of screen contents. By operation in videomodes without |
||
2771 | LFB gs points to some data area in the kernel, and all functions |
||
2772 | of screen output fulfil honesty double operation on writing |
||
2773 | directly to the screen and writing to this buffer. In result |
||
2774 | at reading contents of this buffer the results correspond to |
||
2775 | screen contents (with, generally speaking, large color |
||
2776 | resolution), and writing is ignored. |
||
2777 | One exception is the mode 320*200, for which main loop of the |
||
2778 | system thread updates the screen according to mouse movements. |

118 | diamond | 2934 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 2935 | ====================================================================== |
118 | diamond | 2936 | The debug board is the global system buffer (with the size |
499 | diamond | 2937 | 1024 bytes), to which any program can write (generally speaking, |
118 | diamond | 2938 | arbitrary) data and from which other program can read these data. |
2939 | By the agreement written data are text strings interpreted as |
||
2940 | debug messages on a course of program execution. The kernel in |
||
2941 | some situations also writes to the debug board information on |
||
2942 | execution of some functions; by the agreement kernel messages |
||
2943 | begins from the prefix "K : ". |
||
2944 | For view of the debug board the application 'board' was created, |
||
2945 | which reads data from the buffer and displays them in its window. |
||
2946 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
2947 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 2948 | but also does not prevent. |
118 | diamond | 2949 | Because debugger has been written, the value of the debug board |
2950 | has decreased, as debugger allows to inspect completely a course of |
||
2951 | program execution without any efforts from the direction of program |
||
2952 | itself. Nevertheless in some cases the debug board is still useful. |
||
114 | mikedld | 2953 | |

2960 | * function does not return value |
||
2961 | Remarks: |
||
118 | diamond | 2962 | * Byte is written to the buffer. Buffer size is 512 bytes. |
2963 | At buffer overflow all obtained data are lost. |
||
2964 | * For output to the debug board of more complicated objects |
||
2965 | (strings, numbers) it is enough to call this function in cycle. |
||
2966 | It is possible not to write the appropriate code manually and use |
||
2967 | file 'debug.inc', which is included into the distributive. |

3175 | * Previously the window must be defined by function 0. |
||
114 | mikedld | 3176 | It sets initial coordinates and sizes of the window. |
118 | diamond | 3177 | * Sizes of the window are understood in sense of function 0, |
3178 | that is one pixel less than real sizes. |
||
3179 | * The function call for maximized windows is simply ignored. |
||
3180 | * For windows of appropriate styles position and/or sizes can be |

3548 | ====================================================================== |
||
3549 | Parameters: |
||
3550 | * eax = 68 - function number |
||
1077 | Galkov | 3551 | * ebx = 24 - subfunction number |
3552 | * ecx = address of the new exception handler |
||
1662 | Nasarus | 3553 | * edx = the mask of handled exceptions |
1077 | Galkov | 3554 | Returned value: |
3555 | * eax = address of the old exception handler (0, if it was not set) |
||
1662 | Nasarus | 3556 | * ebx = the old mask of handled exceptions |
1077 | Galkov | 3557 | Remarks: |
1662 | Nasarus | 3558 | * Bit number in mask of exceptions corresponds to exception number |
3559 | in CPU-specification (Intel-PC). For example, FPU exceptions have |
||
3560 | number 16 (#MF), and SSE exceptions - 19 (#XF). |
||
3561 | * The current implementation ignores the inquiry for hook of 7 |
||
3562 | exception - the system handles #NM by its own. |
||
3563 | * The exception handler is called with exception number as first |
||
3564 | (and only) stack parameter. So, correct exit from the handler is |
||
3565 | RET 4. It returns to the instruction, that caused the exception, |
||
3566 | for faults, and to the next instruction for traps (see |
||
3567 | classification of exceptions in CPU specification). |
||
3568 | * When user handler receives control, the corresponding bit in |
||
3569 | the exception mask is cleared. Raising this exception |
||
3570 | in consequence leads to default handling, that is, |
||
3571 | terminating the application in absence of debugger or |
||
3572 | suspend with notification of debugger otherwise. |
||
3573 | * After user handler completes critical operations, it can set |
||
3574 | the corresponding bit in the exception mask with subfunction 25. |
||
3575 | Also user handler is responsible for clearing exceptions flags in |
||
3576 | FPU and/or SSE. |

118 | diamond | 5312 | * 1 = redraw event (is reset by call to function 0) |
5313 | * 2 = key on keyboard is pressed (acts, only when the window is |
||
5314 | active) or hotkey is pressed; is reset, when all keys from |
||
5315 | the buffer are read out by function 2 |
||
5316 | * 3 = button is pressed, defined earlier by function 8 |
||
5317 | (or close button, created implicitly by function 0; |
||
5318 | minimize button is handled by the system and sends no message; |
||
5319 | acts, only when the window is active; |
||
5320 | is reset when all buttons from the buffer |
||
5321 | are read out by function 17) |

5322 | * 4 = reserved (in current implementation never comes even after |
||
5323 | unmasking by function 40) |

2513 | mario79 | 5324 | * 5 = kernel finished redrawing of the desktop background |
118 | diamond | 5325 | * 6 = mouse event (something happened - button pressing or moving; |
5326 | is reset at reading) |
||
5327 | * 7 = IPC event (see function 60 - |
||
5328 | Inter Process Communication; is reset at reading) |

5331 | debug subsystem) |
||
5332 | * 16..31 = event with appropriate IRQ |
||
5333 | (16=IRQ0, 31=IRQ15) (is reset after reading all IRQ data) |
