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6473	pathoswith	31	* Y=0,2 window types are outdated and should not be used anymore,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).
		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
		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 -

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.

114	mikedld	2726	Remarks:

		2731	Same events occur in other cases too, which meet much more often,
		2732	than videomode change.
		2733	* By operation in videomodes with LFB the selector gs points to

118	diamond	2901	The debug board is the global system buffer (with the size
499	diamond	2902	1024 bytes), to which any program can write (generally speaking,
118	diamond	2903	arbitrary) data and from which other program can read these data.
		2904	By the agreement written data are text strings interpreted as

		2906	some situations also writes to the debug board information on
		2907	execution of some functions; by the agreement kernel messages
		2908	begins from the prefix "K : ".
		2909	For view of the debug board the application 'board' was created,
		2910	which reads data from the buffer and displays them in its window.
		2911	'board' interpretes the sequence of codes 13,10 as newline.

		3526	in CPU-specification (Intel-PC). For example, FPU exceptions have
		3527	number 16 (#MF), and SSE exceptions - 19 (#XF).
		3528	* The current implementation ignores the inquiry for hook of 7
		3529	exception - the system handles #NM by its own.
		3530	* The exception handler is called with exception number as first
		3531	(and only) stack parameter. So, correct exit from the handler is
		3532	RET 4. It returns to the instruction, that caused the exception,
		3533	for faults, and to the next instruction for traps (see
		3534	classification of exceptions in CPU specification).
		3535	* When user handler receives control, the corresponding bit in
		3536	the exception mask is cleared. Raising this exception
		3537	in consequence leads to default handling, that is,
		3538	terminating the application in absence of debugger or
		3539	suspend with notification of debugger otherwise.
		3540	* After user handler completes critical operations, it can set
		3541	the corresponding bit in the exception mask with subfunction 25.
		3542	Also user handler is responsible for clearing exceptions flags in
		3543	FPU and/or SSE.
