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
6171	leency	31	* Y=0,2 window types are outdated and should not be used anymore,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,
		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).
		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
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

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.

5682	leency	186	2 = 8x16 UTF-16LE
		187	3 = 8x16 UTF-8
5848	pathoswith	188	* C=0 - draw to the window,
		189	C=1 - draw to the user buffer (edi)
		190	* SSS = (size multiplier)-1, so 0 = x1, 7 = x8
118	diamond	191	* edx = pointer to the beginning of the string

		198	Remarks:
5682	leency	199	* You can not use B=1 and C=1 at the same time, since both use edi.

		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

		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.

		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

		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 -

114	mikedld	346	16 Mb (0x1000000)
		347	* PID=1
142	diamond	348	* coordinates and sizes of the window and the client area are by
		349	convention set to 0
118	diamond	350	* status of the slot is always 0 (running)
		351	* the execution time adds of time leaving on operations itself
		352	and idle time in waiting for interrupt (which can be got by call
		353	to subfunction 4 of function 18).
		354	* Beginning from slot 2, the normal applications are placed.
1662	Nasarus	355	* The normal applications are placed in memory at the address
		356
118	diamond	357	There is no intersection, as each process has its own page table.
		358	* At creation of the thread it is assigned the slot
		359	in the system table and identifier (Process/Thread IDentifier =
		360	PID/TID), which do not vary with time for given thread.
		361	After completion of the thread its slot can be anew used
		362	for another thread. The thread identifier can not be assigned
		363	to other thread even after completion of this thread.
		364	Identifiers, assigned to new threads, grow monotonously.
		365	* If the thread has not yet defined the window by call to
		366	function 0, the position and the sizes
		367	of its window are considered to be zero.
142	diamond	368	* Coordinates of the client area are relative to the window.
118	diamond	369	* At the moment only the part of the buffer by a size
4264	0CodErr	370	76 = 0x4C bytes is used. Nevertheless it is recommended to use
118	diamond	371	1-Kb buffer for the future compatibility, in the future
		372	some fields can be added.

118	diamond	2407	=================== Function 50 - set window shape. ==================
114	mikedld	2408	======================================================================
118	diamond	2409	Normal windows have rectangular shape. This function can give to
		2410	a window any shape. The shape is given by a set of points inside
		2411	the base rectangle belonging to a window. Position and coordinates
		2412	of the base rectangle are set by function 0
		2413	and changed by function 67.

118	diamond	2415	--------------------------- Set shape data ---------------------------
114	mikedld	2416	Parameters:
118	diamond	2417	* eax = 50 - function number
		2418	* ebx = 0 - subfunction number
		2419	* ecx = pointer to shape data (array of bytes 0/1)

118	diamond	2425	* eax = 50 - function number
		2426	* ebx = 1 - subfunction number
		2427	* ecx sets a scale: each byte of data defines
		2428	(2^scale)*(2^scale) pixels
114	mikedld	2429	Returned value:
		2430	* function does not return value
		2431	Remarks:
118	diamond	2432	* Default scale is 0 (scale factor is 1). If in the shape data
		2433	one byte corresponds to one pixel, there is no necessity
		2434	to set scale.
		2435	* Let's designate xsize = window width (in pixels), ysize = height;
		2436	pay attention, that they are one pixel more than defined by
114	mikedld	2437	functions 0, 67.
118	diamond	2438	* On definition of scale xsize and ysize must be divisible
		2439	on 2^scale.
		2440	* Byte of data on offset 'a' must be 0/1 and defines belonging
		2441	to a window of square with the side 2^scale (if scale=0,
		2442	this is one pixel) and coordinates of the left upper corner
114	mikedld	2443	(a mod (xsize shr scale), a div (xsize shr scale))
118	diamond	2444	* Data size: (xsize shr scale)*(ysize shr scale).
		2445	* Data must be presented in the memory and not change
		2446	after set of shape.
		2447	* The system views the shape data at every window redraw by
		2448	function 0.
		2449	* The call of subfunction 0 with NULL pointer results in return
		2450	to the rectangular shape.

118	diamond	2655	==== Function 61 - get parameters for the direct graphics access. ====
114	mikedld	2656	======================================================================
118	diamond	2657	The data of the graphics screen (the memory area which displays
		2658	screen contents) are accessible to a program directly, without
		2659	any system calls, through the selector gs:
5871	hidnplayr	2660	mov eax, [gs:0]
118	diamond	2661	places in eax the first dword of the buffer, which contains
		2662	information on color of the left upper point (and, possibly, colors
		2663	of several following).
5871	hidnplayr	2664	mov [gs:0], eax
118	diamond	2665	by work in VESA modes with LFB sets color of the left upper point
		2666	(and, possibly, colors of several following).
		2667	To interpret the data of graphics screen program needs to know
		2668	some parameters, returning by this function.
114	mikedld	2669	Remarks:
118	diamond	2670	* Graphics parameters changes very seldom at work,
		2671	namely, only in cases, when user works with the application VRR.
		2672	* At videomode change the system redraws all windows (event
		2673	with code 1) and redraws the background (event 5).
		2674	Same events occur in other cases too, which meet much more often,
		2675	than videomode change.
		2676	* By operation in videomodes with LFB the selector gs points to
		2677	LFB itself, so reading/writing on gs result directly in
		2678	change of screen contents. By operation in videomodes without
		2679	LFB gs points to some data area in the kernel, and all functions
		2680	of screen output fulfil honesty double operation on writing
		2681	directly to the screen and writing to this buffer. In result
		2682	at reading contents of this buffer the results correspond to
		2683	screen contents (with, generally speaking, large color
		2684	resolution), and writing is ignored.
		2685	One exception is the mode 320*200, for which main loop of the
		2686	system thread updates the screen according to mouse movements.

114	mikedld	2843	======================================================================
118	diamond	2844	The debug board is the global system buffer (with the size
499	diamond	2845	1024 bytes), to which any program can write (generally speaking,
118	diamond	2846	arbitrary) data and from which other program can read these data.
		2847	By the agreement written data are text strings interpreted as
		2848	debug messages on a course of program execution. The kernel in
		2849	some situations also writes to the debug board information on
		2850	execution of some functions; by the agreement kernel messages
		2851	begins from the prefix "K : ".
		2852	For view of the debug board the application 'board' was created,
		2853	which reads data from the buffer and displays them in its window.
		2854	'board' interpretes the sequence of codes 13,10 as newline.
		2855	A character with null code in an end of line is not necessary,
114	mikedld	2856	but also does not prevent.
118	diamond	2857	Because debugger has been written, the value of the debug board
		2858	has decreased, as debugger allows to inspect completely a course of
		2859	program execution without any efforts from the direction of program
		2860	itself. Nevertheless in some cases the debug board is still useful.

		3458	* The current implementation ignores the inquiry for hook of 7
		3459	exception - the system handles #NM by its own.
		3460	* The exception handler is called with exception number as first
		3461	(and only) stack parameter. So, correct exit from the handler is
		3462	RET 4. It returns to the instruction, that caused the exception,
		3463	for faults, and to the next instruction for traps (see
		3464	classification of exceptions in CPU specification).
		3465	* When user handler receives control, the corresponding bit in
		3466	the exception mask is cleared. Raising this exception
		3467	in consequence leads to default handling, that is,
		3468	terminating the application in absence of debugger or
		3469	suspend with notification of debugger otherwise.
		3470	* After user handler completes critical operations, it can set
		3471	the corresponding bit in the exception mask with subfunction 25.
		3472	Also user handler is responsible for clearing exceptions flags in
		3473	FPU and/or SSE.

114	mikedld	4808	Returned value:
118	diamond	4809	* function does not return neither value nor control
114	mikedld	4810	Remarks:
118	diamond	4811	* If the process did not create threads obviously, it has only
		4812	one thread, which termination results in process termination.
		4813	* If the current thread is last in the process, its termination
		4814	also results in process terminates.
		4815	* This function terminates the current thread. Other thread can be
		4816	killed by call to subfunction 2 of function 18.

114	mikedld	4820	======================================================================
		4821	=========================== List of events ===========================
		4822	======================================================================
118	diamond	4823	Next event can be retrieved by the call of one from functions 10
		4824	(to wait for event), 11 (to check without waiting), 23
		4825	(to wait during the given time).
		4826	These functions return only those events, which enter into a mask set
		4827	by function 40. By default it is first three,
		4828	there is enough for most applications.
114	mikedld	4829	Codes of events:
118	diamond	4830	* 1 = redraw event (is reset by call to function 0)
		4831	* 2 = key on keyboard is pressed (acts, only when the window is
		4832	active) or hotkey is pressed; is reset, when all keys from
		4833	the buffer are read out by function 2
		4834	* 3 = button is pressed, defined earlier by function 8
		4835	(or close button, created implicitly by function 0;
		4836	minimize button is handled by the system and sends no message;
		4837	acts, only when the window is active;
		4838	is reset when all buttons from the buffer
		4839	are read out by function 17)
		4840	* 4 = reserved (in current implementation never comes even after
		4841	unmasking by function 40)
2513	mario79	4842	* 5 = kernel finished redrawing of the desktop background
118	diamond	4843	* 6 = mouse event (something happened - button pressing or moving;
		4844	is reset at reading)
		4845	* 7 = IPC event (see function 60 -
		4846	Inter Process Communication; is reset at reading)
		4847	* 8 = network event (is reset at reading)
		4848	* 9 = debug event (is reset at reading; see
		4849	debug subsystem)
		4850	* 16..31 = event with appropriate IRQ
		4851	(16=IRQ0, 31=IRQ15) (is reset after reading all IRQ data)

118	diamond	4854	=================== Error codes of the file system ===================
114	mikedld	4855	======================================================================
118	diamond	4856	* 0 = success
		4857	* 2 = function is not supported for the given file system
		4858	* 3 = unknown file system
		4859	* 5 = file not found
		4860	* 6 = end of file, EOF
		4861	* 7 = pointer lies outside of application memory
		4862	* 8 = disk is full
6235	pathoswith	4863	* 9 = file system error
114	mikedld	4864	* 10 = access denied
118	diamond	4865	* 11 = device error
6235	pathoswith	4866	* 12 = file system requires more memory
		4867
118	diamond	4868	Application start functions can return also following errors:
		4869	* 30 = 0x1E = not enough memory
		4870	* 31 = 0x1F = file is not executable
		4871	* 32 = 0x20 = too many processes
