2010 | serge | 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 | |
15 | |||
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 |
6240 | serge | 31 | * Y=0,2 window types are outdated and should not be used anymore, |
32 | they are retained for compatibility with old programs. |
||
33 | * other possible values (from 5 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 |
4265 | Serge | 36 | of the working area of the window (are ignored for style Y=1) |
114 | mikedld | 37 | * X = DCBA (bits) |
6240 | serge | 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 |
||
4265 | Serge | 47 | * Y=0 - usual window, Y=1 - unmovable window (works for all window styles) |
6240 | serge | 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. |
2434 | 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). |
||
74 | * The sizes of the window are understood in sence of coordinates |
||
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 |
6240 | serge | 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 |

6078 | serge | 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, |
||
5201 | serge | 125 | ah=code of the pressed key, |
126 | bits 16-23 = contain scancode for pressed key in ASCII mode, |
||
127 | in the scancodes mode this bits cleared. |
||
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. |

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. |

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 | 326 | Remarks: |
118 | diamond | 327 | * Slots are numbered starting from 1. |
328 | * Returned value is not a total number of threads, because there |
||
329 | can be free slots. |
||
330 | * When process is starting, system automatically creates |
||
331 | execution thread. |
||
332 | * Function gives information on the thread. Each process has |
||
333 | at least one thread. One process can create many threads, |
||
334 | in this case each thread has its own slot and the fields |
||
335 | +10, +22, +26 in these slots coincide. |
||
336 | Applications have no common way to define whether two threads |
||
114 | mikedld | 337 | belong to one process. |
118 | diamond | 338 | * The active window - window on top of the window stack - |
339 | receives the messages on a keyboard input. For such window |
||
340 | the position in the window stack coincides with returned value. |
||
341 | * Slot 1 corresponds to special system thread, for which: |
||
342 | * the window is in the bottom of the window stack, the fields |
||
343 | +4 and +6 contain value 1 |
||
344 | * name of the process - "OS/IDLE" (supplemented by spaces) |
||

||
114 | mikedld | 2425 | Returned value: |
2426 | * function does not return value |
||
2427 | Remarks: |
||
118 | diamond | 2428 | * Default scale is 0 (scale factor is 1). If in the shape data |
2429 | one byte corresponds to one pixel, there is no necessity |
||
2430 | to set scale. |
||
2431 | * Let's designate xsize = window width (in pixels), ysize = height; |
||
2432 | pay attention, that they are one pixel more than defined by |
||
114 | mikedld | 2433 | functions 0, 67. |
118 | diamond | 2434 | * On definition of scale xsize and ysize must be divisible |
2435 | on 2^scale. |
||
2436 | * Byte of data on offset 'a' must be 0/1 and defines belonging |
||
2437 | to a window of square with the side 2^scale (if scale=0, |
||
2438 | this is one pixel) and coordinates of the left upper corner |
||
114 | mikedld | 2439 | (a mod (xsize shr scale), a div (xsize shr scale)) |
118 | diamond | 2440 | * Data size: (xsize shr scale)*(ysize shr scale). |
2441 | * Data must be presented in the memory and not change |
||
2442 | after set of shape. |
||
2443 | * The system views the shape data at every window redraw by |
||
2444 | function 0. |
||
2445 | * The call of subfunction 0 with NULL pointer results in return |
||
2446 | to the rectangular shape. |

114 | mikedld | 2652 | ====================================================================== |
118 | diamond | 2653 | The data of the graphics screen (the memory area which displays |
2654 | screen contents) are accessible to a program directly, without |
||
2655 | any system calls, through the selector gs: |
||
5984 | serge | 2656 | mov eax, [gs:0] |
118 | diamond | 2657 | places in eax the first dword of the buffer, which contains |
2658 | information on color of the left upper point (and, possibly, colors |
||
2659 | of several following). |
||
5984 | serge | 2660 | mov [gs:0], eax |
118 | diamond | 2661 | by work in VESA modes with LFB sets color of the left upper point |
2662 | (and, possibly, colors of several following). |
||
2663 | To interpret the data of graphics screen program needs to know |
||
2664 | some parameters, returning by this function. |
||
114 | mikedld | 2665 | Remarks: |
118 | diamond | 2666 | * Graphics parameters changes very seldom at work, |
2667 | namely, only in cases, when user works with the application VRR. |
||
2668 | * At videomode change the system redraws all windows (event |
||
2669 | with code 1) and redraws the background (event 5). |
||
2670 | Same events occur in other cases too, which meet much more often, |
||
2671 | than videomode change. |
||
2672 | * By operation in videomodes with LFB the selector gs points to |
||
2673 | LFB itself, so reading/writing on gs result directly in |
||
2674 | change of screen contents. By operation in videomodes without |
||
2675 | LFB gs points to some data area in the kernel, and all functions |
||
2676 | of screen output fulfil honesty double operation on writing |
||
2677 | directly to the screen and writing to this buffer. In result |
||
2678 | at reading contents of this buffer the results correspond to |
||
2679 | screen contents (with, generally speaking, large color |
||
2680 | resolution), and writing is ignored. |
||
2681 | One exception is the mode 320*200, for which main loop of the |
||
2682 | system thread updates the screen according to mouse movements. |

118 | diamond | 2838 | ============== Function 63 - work with the debug board. ============== |
114 | mikedld | 2839 | ====================================================================== |
118 | diamond | 2840 | The debug board is the global system buffer (with the size |
499 | diamond | 2841 | 1024 bytes), to which any program can write (generally speaking, |
118 | diamond | 2842 | arbitrary) data and from which other program can read these data. |
2843 | By the agreement written data are text strings interpreted as |
||
2844 | debug messages on a course of program execution. The kernel in |
||
2845 | some situations also writes to the debug board information on |
||
2846 | execution of some functions; by the agreement kernel messages |
||
2847 | begins from the prefix "K : ". |
||
2848 | For view of the debug board the application 'board' was created, |
||
2849 | which reads data from the buffer and displays them in its window. |
||
2850 | 'board' interpretes the sequence of codes 13,10 as newline. |
||
2851 | A character with null code in an end of line is not necessary, |
||
114 | mikedld | 2852 | but also does not prevent. |
118 | diamond | 2853 | Because debugger has been written, the value of the debug board |
2854 | has decreased, as debugger allows to inspect completely a course of |
||
2855 | program execution without any efforts from the direction of program |
||
2856 | itself. Nevertheless in some cases the debug board is still useful. |

2867 | At buffer overflow all obtained data are lost. |
||
2868 | * For output to the debug board of more complicated objects |
||
2869 | (strings, numbers) it is enough to call this function in cycle. |
||
2870 | It is possible not to write the appropriate code manually and use |
||
2871 | file 'debug.inc', which is included into the distributive. |

3441 | Parameters: |
||
3442 | * eax = 68 - function number |
||
1077 | Galkov | 3443 | * ebx = 24 - subfunction number |
3444 | * ecx = address of the new exception handler |
||
2010 | serge | 3445 | * edx = the mask of handled exceptions |
1077 | Galkov | 3446 | Returned value: |
3447 | * eax = address of the old exception handler (0, if it was not set) |
||
2010 | serge | 3448 | * ebx = the old mask of handled exceptions |
1077 | Galkov | 3449 | Remarks: |
2010 | serge | 3450 | * Bit number in mask of exceptions corresponds to exception number |
3451 | in CPU-specification (Intel-PC). For example, FPU exceptions have |
||
3452 | number 16 (#MF), and SSE exceptions - 19 (#XF). |
||
3453 | * The current implementation ignores the inquiry for hook of 7 |
||
3454 | exception - the system handles #NM by its own. |
||
3455 | * The exception handler is called with exception number as first |
||
3456 | (and only) stack parameter. So, correct exit from the handler is |
||
3457 | RET 4. It returns to the instruction, that caused the exception, |
||
3458 | for faults, and to the next instruction for traps (see |
||
3459 | classification of exceptions in CPU specification). |
||
3460 | * When user handler receives control, the corresponding bit in |
||
3461 | the exception mask is cleared. Raising this exception |
||
3462 | in consequence leads to default handling, that is, |
||
3463 | terminating the application in absence of debugger or |
||
3464 | suspend with notification of debugger otherwise. |
||
3465 | * After user handler completes critical operations, it can set |
||
3466 | the corresponding bit in the exception mask with subfunction 25. |
||
3467 | Also user handler is responsible for clearing exceptions flags in |
||
3468 | FPU and/or SSE. |

||
114 | mikedld | 4001 | * Any folder on the disk, except for root, contains two special |
118 | diamond | 4002 | entries "." and "..", identifying accordingly the folder itself |
4003 | and the parent folder. |
||
4004 | * The function allows also to read virtual folders "/", "/rd", |
||
4005 | "/fd", "/hd[n]", thus attributes of subfolders are set to 0x10, |
||
4006 | and times and dates are zeroed. An alternative way to get the |
||
4007 | equipment information - subfunction 11 of function 18. |
