SYSTEM FUNCTIONS of OS Kolibri 0.7.7.0
|
||
|
||
Number of the function is located in the register eax.
|
||
The call of the system function is executed by "int 0x40" command.
|
||
All registers except explicitly declared in the returned value,
|
||
including eflags, are preserved.
|
||
|
||
|
||
======================================================================
|
||
============== Function 0 - define and draw the window. ==============
|
||
======================================================================
|
||
Defines an application window. Draws a frame of the window, header and
|
||
working area. For skinned windows defines standard close and minimize
|
||
buttons.
|
||
Parameters:
|
||
* eax = 0 - function number
|
||
* ebx = [coordinate on axis x]*65536 + [size on axis x]
|
||
* ecx = [coordinate on axis y]*65536 + [size on axis y]
|
||
* edx = 0xXYRRGGBB, where:
|
||
* Y = style of the window:
|
||
* Y=1 - only define window area, draw nothing
|
||
* Y=3 - skinned window
|
||
* Y=4 - skinned fixed-size window
|
||
* Y=0,2 window types are outdated and should not be used anymore,
|
||
they are retained for compatibility with old programs.
|
||
* other possible values (from 5 to 15) are reserved,
|
||
function call with such Y is ignored
|
||
* RR, GG, BB = accordingly red, green, blue components of a color
|
||
of the working area of the window (are ignored for style Y=1)
|
||
* X = DCBA (bits)
|
||
* A = 1 - window has caption
|
||
* B = 1 - coordinates of all graphics primitives are relative to
|
||
window client area
|
||
* C = 1 - don't fill working area on window draw
|
||
* D = 0 - normal filling of the working area, 1 - gradient
|
||
The following parameters are intended for windows
|
||
of a type I and II, and ignored for styles Y=1,3:
|
||
* esi = 0xXYRRGGBB - color of the header
|
||
* RR, GG, BB define color
|
||
* Y=0 - usual window, Y=1 - unmovable window (works for all window styles)
|
||
* X not used, other values of Y are reserved
|
||
* edi = caption string for styles Y=3,4 (also can be set by func 71.1)
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* Position and sizes of the window are installed by the first
|
||
call of this function and are ignored at subsequent; to change
|
||
position and/or sizes of already created window use function 67.
|
||
* For windows with styles Y=3,4 and caption (A=1) caption string
|
||
is set by the first call of this function and is ignored
|
||
at subsequent (strictly speaking, is ignored after a call to
|
||
subfunction 2 of function 12 - end redraw); to change caption of
|
||
already created window use subfunction 1 of function 71.
|
||
* If the window has appropriate styles, position and/or sizes can be
|
||
changed by user. Current position and sizes can be obtained
|
||
by function 9.
|
||
* The window must fit on the screen. If the transferred
|
||
coordinates and sizes do not satisfy to this condition,
|
||
appropriate coordinate (or, probably, both) is considered as zero,
|
||
and if it does not help too, the appropriate size
|
||
(or, probably, both) is installed in a size of the screen.
|
||
|
||
Further let us designate xpos,ypos,xsize,ysize - values passed
|
||
in ebx,ecx. The coordinates are resulted concerning
|
||
the left upper corner of the window, which, thus, is set as (0,0),
|
||
coordinates of the right lower corner essence (xsize,ysize).
|
||
* The sizes of the window are understood in sense of coordinates
|
||
of the right lower corner. This concerns all other functions too.
|
||
It means, that the real sizes are on 1 pixel more.
|
||
* The window of style Y=1 looks as follows:
|
||
* completely defined by the application
|
||
* The skinned window Y=3,4 looks as follows:
|
||
* draw external frame of width 1 pixel
|
||
with color 'outer' from the skin
|
||
* draw intermediate frame of width 3 pixel
|
||
with color 'frame' from the skin
|
||
* draw internal frame of width 1 pixel
|
||
with color 'inner' from the skin
|
||
* draw header (on bitmaps from the skin) in a rectangle
|
||
(0,0) - (xsize,_skinh-1)
|
||
* if ysize>=26, fill the working area of the window -
|
||
rectangle with the left upper corner (5,_skinh) and right lower
|
||
(xsize-5,ysize-5) with color indicated in edx
|
||
(taking a gradient into account)
|
||
* define two standard buttons: close and minimize
|
||
(see function 8)
|
||
* if A=1 and edi contains (nonzero) pointer to caption string,
|
||
it is drawn in place in header defined in the skin
|
||
* value _skinh is accessible as the result of call
|
||
subfunction 4 of function 48

|
||
Parameters:
|
||
* eax = 1 - function number
|
||
* ebx = x-coordinate (relative to the window)
|
||
* ecx = y-coordinate (relative to the window)
|
||
* edx = 0x00RRGGBB - color of a pixel
|
||

|
||
(low 24 bits are ignored)
|

|
||
============ Function 2 - get the code of the pressed key. ===========
|
||
======================================================================
|
||
Takes away the code of the pressed key from the buffer.
|
||
Parameters:
|
||
* eax = 2 - function number
|
||
Returned value:
|
||
* if the buffer is empty, function returns eax=1
|
||
* if the buffer is not empty, function returns al=0,
|
||
ah=code of the pressed key,
|
||
bits 16-23 = contain scancode for pressed key in ASCII mode,
|
||
in the scancodes mode this bits cleared.
|
||
bits 23-31 = zero
|
||
* if there is "hotkey", function returns al=2,
|
||
ah=scancode of the pressed key (0 for control keys),
|
||
high word of eax contains a status of control keys at the moment
|
||
of pressing a hotkey
|
||
Remarks:
|
||
* There is a common system buffer of the pressed keys
|
||
by a size of 120 bytes, organized as queue.
|
||
* There is one more common system buffer on 120 "hotkeys".
|
||
* If the application with the inactive window calls this function,
|
||
the buffer of the pressed keys is considered to be empty.
|
||
* By default this function returns ASCII-codes; to switch
|
||
to the scancodes mode (and back) use function 66.
|
||
However, hotkeys are always notificated as scancodes.
|
||
* To find out, what keys correspond to what codes, start
|
||
the application keyascii and scancode.
|
||
* Scancodes come directly from keyboard and are fixed;
|
||
ASCII-codes turn out with usage of the conversion tables,
|
||
which can be set by subfunction 2 of function 21
|
||
and get by subfunction 2 of function 26.
|
||
* As a consequence, ASCII-codes take into account current
|
||
keyboard layout (rus/en) as opposed to scancodes.
|
||
* This function notifies only about those hotkeys, which were
|
||
defined by this thread by subfunction 4 of function 66.

======================================================================
|
||
Parameters:
|
||
* eax = 3 - function number
|
||
Returned value:
|
||
* eax = 0x00SSMMHH, where HH:MM:SS = Hours:Minutes:Seconds
|
||
* each item is BCD-number, for example,
|
||
for time 23:59:59 function returns 0x00595923
|
||
Remarks:
|
||
* See also subfunction 9 of function 26 - get time from
|
||
the moment of start of the system; it is more convenient, because
|
||
returns simply DWORD-value of the time counter.
|
||
* System time can be set by function 22.

|
||
* ecx = 0xXXRRGGBB, where
|
||
* RR, GG, BB specify text color
|
||
* XX = ABFFCSSS (bits):
|
||
* A=1 - output zero terminated string
|
||
* B=1 - fill background (color = edi)
|
||
* FF specifies the font and encoding:
|
||
0 = 6x9 cp866
|
||
1 = 8x16 cp866

|
||
3 = 8x16 UTF-8
|
||
* C=0 - draw to the window,
|
||
C=1 - draw to the user buffer (edi)
|
||
* SSS = (size multiplier)-1, so 0 = x1, 7 = x8
|
||
* edx = pointer to the beginning of the string
|
||
* esi = for A=0 length of the string, for A=1 is ignored
|
||
* edi = for B=1 color to fill background,
|
||
for C=1 pointer to user buffer
|
||
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* You can not use B=1 and C=1 at the same time, since both use edi.
|
||
* When SSS=0, font may be smoothed, depending on system setting.
|
||
* User buffer structure:

|
||
* ebx = time in the 1/100 of second
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* Passing ebx=0 does not transfer control to the next process
|
||
and does not make any operations at all. If it is really required
|
||
to transfer control to the next process (to complete a current
|
||
time slice), use subfunction 1 of function 68.

* eax = 8 - function number
|
||
* ebx = [coordinate on axis x]*65536 + [size on axis x]
|
||
* ecx = [coordinate on axis y]*65536 + [size on axis y]
|
||
* edx = 0xXYnnnnnn, where:
|
||
* nnnnnn = identifier of the button
|
||
* high (31st) bit of edx is cleared
|
||
* if 30th bit of edx is set - do not draw the button
|
||
* if 29th bit of edx is set - do not draw a frame
|
||
at pressing the button
|
||
* esi = 0x00RRGGBB - color of the button
|

* edx = 0x80nnnnnn, where nnnnnn - identifier of the button
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* Sizes of the button must be more than 0 and less than 0x8000.
|
||
* For skinned windows definition of the window
|
||
(call of 0th function) creates two standard buttons -
|
||
for close of the window with identifier 1 and
|
||
for minimize of the window with identifier 0xffff.
|
||
* The creation of two buttons with same identifiers is admitted.
|
||
* The button with the identifier 0xffff at pressing is interpreted
|
||
by the system as the button of minimization, the system handles
|
||
such pressing independently, not accessing to the application.
|
||
In rest it is usual button.
|
||
* Total number of buttons for all applications is limited to 4095.

======================================================================
|
||
Parameters:
|
||
* eax = 9 - function number
|
||
* ebx = pointer to 1-Kb buffer
|
||
* ecx = number of the slot of the thread
|
||
ecx = -1 - get information on the current thread
|
||
Returned value:
|
||
* eax = maximum number of the slot of a thread
|
||
* buffer pointed to by ebx contains the following information:
|
||
* +0: dword: usage of the processor (how many time units
|
||
per second leaves on execution of this thread)
|
||
* +4: word: position of the window of thread in the window stack
|
||
* +6: word: (has no relation to the specified thread)
|
||
number of the thread slot, which window has in the window stack
|
||
position ecx
|
||
* +8: word: reserved
|
||
* +10 = +0xA: 11 bytes: name of the process
|
||
(name of the started file - executable file without extension)
|
||
* +21 = +0x15: byte: reserved, this byte is not changed
|
||
* +22 = +0x16: dword: address of the process in memory
|
||
* +26 = +0x1A: dword: size of used memory - 1
|
||
* +30 = +0x1E: dword: identifier (PID/TID)
|
||
* +34 = +0x22: dword: coordinate of the thread window on axis x
|
||
* +38 = +0x26: dword: coordinate of the thread window on axis y
|

* +46 = +0x2E: dword: size of the thread window on axis y
|
||
* +50 = +0x32: word: status of the thread slot:
|
||
* 0 = thread is running
|
||
* 1 = thread is suspended
|
||
* 2 = thread is suspended while waiting for event
|
||
* 3 = thread is terminating as a result of call to function -1
|
||
or under duress as a result of call to subfunction 2
|
||
of function 18 or termination of the system
|
||
* 4 = thread is terminating as a result of exception
|
||
* 5 = thread waits for event
|
||
* 9 = requested slot is free, all other information on the slot
|
||
is not meaningful
|
||
* +52 = +0x34: word: reserved, this word is not changed
|
||
* +54 = +0x36: dword: coordinate of the client area on axis x
|

* +70 = +0x46: byte: state of the window - bitfield
|
||
* bit 0 (mask 1): window is maximized
|
||
* bit 1 (mask 2): window is minimized to panel
|
||
* bit 2 (mask 4): window is rolled up
|
||
* +71 = +0x47: dword: event mask
|
||
* +75 = +0x4B: byte: keyboard mode(ASCII = 0; SCAN = 1)
|
||
Remarks:
|
||
* Slots are numbered starting from 1.
|
||
* Returned value is not a total number of threads, because there
|
||
can be free slots.
|
||
* When process is starting, system automatically creates
|
||
execution thread.
|
||
* Function gives information on the thread. Each process has
|
||
at least one thread. One process can create many threads,
|
||
in this case each thread has its own slot and the fields
|
||
+10, +22, +26 in these slots coincide.
|
||
Applications have no common way to define whether two threads
|
||
belong to one process.
|
||
* The active window - window on top of the window stack -
|
||
receives the messages on a keyboard input. For such window
|
||
the position in the window stack coincides with returned value.
|
||
* Slot 1 corresponds to special system thread, for which:
|
||
* the window is in the bottom of the window stack, the fields
|
||
+4 and +6 contain value 1
|
||
* name of the process - "OS/IDLE" (supplemented by spaces)
|
||
* address of the process in memory is 0, size of used memory is
|
||
16 Mb (0x1000000)
|
||
* PID=1
|
||
* coordinates and sizes of the window and the client area are by
|
||
convention set to 0
|
||
* status of the slot is always 0 (running)
|
||
* the execution time adds of time leaving on operations itself
|
||
and idle time in waiting for interrupt (which can be got by call
|
||
to subfunction 4 of function 18).
|
||
* Beginning from slot 2, the normal applications are placed.
|
||
* The normal applications are placed in memory at the address
|
||
0 (kernel constant 'std_application_base_address').
|
||
There is no intersection, as each process has its own page table.
|
||
* At creation of the thread it is assigned the slot
|
||
in the system table and identifier (Process/Thread IDentifier =
|
||
PID/TID), which do not vary with time for given thread.
|
||
After completion of the thread its slot can be anew used
|
||
for another thread. The thread identifier can not be assigned
|
||
to other thread even after completion of this thread.
|
||
Identifiers, assigned to new threads, grow monotonously.
|
||
* If the thread has not yet defined the window by call to
|
||
function 0, the position and the sizes
|
||
of its window are considered to be zero.
|
||
* Coordinates of the client area are relative to the window.
|
||
* At the moment only the part of the buffer by a size
|
||
76 = 0x4C bytes is used. Nevertheless it is recommended to use
|
||
1-Kb buffer for the future compatibility, in the future
|
||
some fields can be added.

||
* ecx = 1 for Sunday, ..., 7 for Saturday
|
||
* ebx = 3 - set alarm clock
|
||
* ecx = 0x00SSMMHH
|
||
Returned value:
|
||
* eax = 0 - success
|
||
* eax = 1 - incorrect parameter
|
||
* eax = 2 - CMOS-battery was unloaded
|
||
Remarks:
|
||
* Value of installation of day of week seems to be doubtful,
|
||
as it a little where is used
|
||
(day of week can be calculated by date).
|
||
* Alarm clock can be set on operation in the given time every day.
|
||
But there is no existing system function to disable it.
|
||
* Operation of alarm clock consists in generation IRQ8.
|
||
* Generally CMOS supports for alarm clock set of value 0xFF
|
||
as one of parameters and it means that the appropriate parameter
|
||
is ignored. But current implementation does not allow this
|
||
(will return 1).
|
||
* Alarm clock is a global system resource; the set of
|
||
an alarm clock cancels automatically the previous set.
|
||
However, at moment no program uses it.

10, 11, 23 - they notify only about events allowed by this mask.
|
||
Parameters:
|
||
* eax = 40 - function number
|
||
* ebx = mask: bit i corresponds to event i+1 (see list of events)
|
||
(set bit permits notice on event)
|
||
bit 31: mouse active/inactive filter
|
||
bit 31 = 0 - inactive window receive mouse events
|
||
bit 31 = 1 - inactive window does not receive mouse events
|
||
bit 30: cursor position filter
|
||
bit 30 = 0 = the window receive mouse events if cursor
|
||
outside window
|
||
bit 30 = 1 - the window does not receive mouse events if cursor
|
||
outside window
|
||
Returned value:

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

* eax = 1 - the thread has not reserved the selected port
|
||
Remarks:
|
||
* Previously the thread must reserve the selected port
|
||
for itself by function 46.
|
||
* Instead of call to this function it is better to use
|
||
processor instructions in/out - this is much
|
||
faster and a bit shorter and easier.

====== Function 46 - reserve/free a group of input/output ports. =====
|
||
======================================================================
|
||
To work with reserved ports an application can access directly by
|
||
commands in/out (recommended way) and can use function 43
|
||
(not recommended way).
|
||
Parameters:
|
||
* eax = 46 - function number
|
||
* ebx = 0 - reserve, 1 - free
|
||
* ecx = start port number

||
* edx = end port number (inclusive)
|
||
Returned value:
|
||
* eax = 0 - success
|
||
* eax = 1 - error
|
||
Remarks:
|
||
* For ports reservation: an error occurs if and only if
|
||
one from the following condition satisfies:
|
||
* start port is more than end port;
|
||
* the selected range contains incorrect port number
|
||
(correct are from 0 to 0xFFFF);
|
||
* limit for the total number of reserved areas is exceeded
|
||
(maximum 255 are allowed);
|
||
* the selected range intersects with any of earlier reserved
|
||
* For ports free: an error is an attempt to free range,
|
||
that was not earlier reserved by this function
|
||
(with same ecx,edx).
|
||
* If an error occurs (for both cases) function performs no action.
|
||
* At booting the system reserves for itself ports
|
||
0..0x2d, 0x30..0x4d, 0x50..0xdf, 0xe5..0xff (inclusively).
|
||
* When a thread terminates, all reserved by it ports
|
||
are freed automatically.

|
||
=================== Function 50 - set window shape. ==================
|
||
======================================================================
|
||
Normal windows have rectangular shape. This function can give to
|
||
a window any shape. The shape is given by a set of points inside
|
||
the base rectangle belonging to a window. Position and coordinates
|
||
of the base rectangle are set by function 0
|
||
and changed by function 67.
|
||
|
||
--------------------------- Set shape data ---------------------------
|
||
Parameters:
|
||
* eax = 50 - function number
|
||
* ebx = 0 - subfunction number
|
||
* ecx = pointer to shape data (array of bytes 0/1)
|
||
Returned value:
|
||
* function does not return value
|
||
|
||
-------------------------- Set shape scale ---------------------------
|
||
Parameters:
|
||
* eax = 50 - function number
|
||
* ebx = 1 - subfunction number
|
||
* ecx sets a scale: each byte of data defines
|
||
(2^scale)*(2^scale) pixels
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* Default scale is 0 (scale factor is 1). If in the shape data
|
||
one byte corresponds to one pixel, there is no necessity
|
||
to set scale.
|
||
* Let's designate xsize = window width (in pixels), ysize = height;
|
||
pay attention, that they are one pixel more than defined by
|
||
functions 0, 67.
|
||
* On definition of scale xsize and ysize must be divisible
|
||
on 2^scale.
|
||
* Byte of data on offset 'a' must be 0/1 and defines belonging
|
||
to a window of square with the side 2^scale (if scale=0,
|
||
this is one pixel) and coordinates of the left upper corner
|
||
(a mod (xsize shr scale), a div (xsize shr scale))
|
||
* Data size: (xsize shr scale)*(ysize shr scale).
|
||
* Data must be presented in the memory and not change
|
||
after set of shape.
|
||
* The system views the shape data at every window redraw by
|
||
function 0.
|
||
* The call of subfunction 0 with NULL pointer results in return
|
||
to the rectangular shape.

========== Function 60 - Inter Process Communication (IPC). ==========
|
||
======================================================================
|
||
IPC is used for message dispatching from one process/thread to
|
||
another. Previously it is necessary to agree how to interpret
|
||
the concrete message.
|
||
|
||
----------- Subfunction 1 - set the area for IPC receiving -----------
|
||
Is called by process-receiver.
|
||
Parameters:
|
||
* eax = 60 - function number
|
||
* ebx = 1 - subfunction number
|
||
* ecx = pointer to the buffer
|
||
* edx = size of the buffer
|
||
Returned value:
|
||
* eax = 0 - always success
|
||
Format of IPC-buffer:
|
||
* +0: dword: if nonzero, buffer is considered locked;
|
||
lock/unlock the buffer, when you work with it and need that
|
||
buffer data are not changed from outside (no new messages)
|
||
* +4: dword: occupied place in the buffer (in bytes)
|
||
* +8: first message
|
||
* +8+n: second message
|
||
* ...
|
||
Format of a message:
|
||
* +0: dword: PID of sender
|
||
* +4: dword: message length (not including this header)
|
||
* +8: n*byte: message data
|
||
|
||
------------------ Subfunction 2 - send IPC message ------------------
|
||
Is called by process-sender.
|
||
Parameters:
|
||
* eax = 60 - function number
|
||
* ebx = 2 - subfunction number
|
||
* ecx = PID of receiver
|
||
* edx = pointer to the message data
|
||
* esi = message length (in bytes)
|
||
Returned value:
|
||
* eax = 0 - success
|
||
* eax = 1 - the receiver has not defined buffer for IPC messages
|
||
(can be, still have no time,
|
||
and can be, this is not right process)
|
||
* eax = 2 - the receiver has blocked IPC-buffer; try to wait a bit
|
||
* eax = 3 - overflow of IPC-buffer of the receiver
|
||
* eax = 4 - process/thread with such PID does not exist
|
||
Remarks:
|
||
* Immediately after writing of IPC-message to the buffer the system
|
||
sends to the receiver the event with code 7 (see event codes).

==== Function 61 - get parameters for the direct graphics access. ====
|
||
======================================================================
|
||
The data of the graphics screen (the memory area which displays
|
||
screen contents) are accessible to a program directly, without
|
||
any system calls, through the selector gs:
|
||
mov eax, [gs:0]
|
||
places in eax the first dword of the buffer, which contains
|
||
information on color of the left upper point (and, possibly, colors
|
||
of several following).
|
||
mov [gs:0], eax
|
||
by work in VESA modes with LFB sets color of the left upper point
|
||
(and, possibly, colors of several following).
|
||
To interpret the data of graphics screen program needs to know
|
||
some parameters, returning by this function.
|
||
Remarks:
|
||
* Graphics parameters changes very seldom at work.
|
||
* At videomode change the system redraws all windows (event
|
||
with code 1) and redraws the background (event 5).
|
||
Same events occur in other cases too, which meet much more often,
|
||
than videomode change.
|
||
* By operation in videomodes with LFB the selector gs points to
|
||
LFB itself, so reading/writing on gs result directly in
|
||
change of screen contents. By operation in videomodes without
|
||
LFB gs points to some data area in the kernel, and all functions
|
||
of screen output fulfil honesty double operation on writing
|
||
directly to the screen and writing to this buffer. In result
|
||
at reading contents of this buffer the results correspond to
|
||
screen contents (with, generally speaking, large color
|
||
resolution), and writing is ignored.
|
||
One exception is the mode 320*200, for which main loop of the
|
||
system thread updates the screen according to mouse movements.

============== Function 63 - work with the debug board. ==============
|
||
======================================================================
|
||
The debug board is the global system buffer (with the size
|
||
1024 bytes), to which any program can write (generally speaking,
|
||
arbitrary) data and from which other program can read these data.
|
||
By the agreement written data are text strings interpreted as
|
||
debug messages on a course of program execution. The kernel in
|
||
some situations also writes to the debug board information on
|
||
execution of some functions; by the agreement kernel messages
|
||
begins from the prefix "K : ".
|
||
For view of the debug board the application 'board' was created,
|
||
which reads data from the buffer and displays them in its window.
|
||
'board' interpretes the sequence of codes 13,10 as newline.
|
||
A character with null code in an end of line is not necessary,
|
||
but also does not prevent.
|
||
Because debugger has been written, the value of the debug board
|
||
has decreased, as debugger allows to inspect completely a course of
|
||
program execution without any efforts from the direction of program
|
||
itself. Nevertheless in some cases the debug board is still useful.
|
||
|
||
----------------------------- Write byte -----------------------------
|
||
Parameters:
|
||
* eax = 63 - function number
|
||
* ebx = 1 - subfunction number
|
||
* cl = data byte
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* Byte is written to the buffer. Buffer size is 512 bytes.
|
||
At buffer overflow all obtained data are lost.
|
||
* For output to the debug board of more complicated objects
|
||
(strings, numbers) it is enough to call this function in cycle.
|
||
It is possible not to write the appropriate code manually and use
|
||
file 'debug.inc', which is included into the distributive.
|
||
|
||
----------------------------- Read byte ------------------------------
|
||
Takes away byte from the buffer.
|
||
Parameters:
|
||
* eax = 63 - function number
|
||
* ebx = 2 - subfunction number
|
||
Returned value:
|
||
* eax = ebx = 0 - the buffer is empty
|
||
* eax = byte, ebx = 1 - byte was successfully read

* ebx = 1 - unique subfunction
|
||
* ecx = new memory size
|
||
Returned value:
|
||
* eax = 0 - success
|
||
* eax = 1 - not enough memory
|
||
Remarks:
|
||
* There is another way to dynamically allocate/free memory -
|
||
subfunctions 12, 13 and 20 of function 68, but after creation
|
||
of the process heap 64 function call will be ignored.
|
||
* The function cannot be used together with 68.11, 68.12, 68.13.
|
||
The function call will be ignored after creation of process heap
|

======================================================================
|
||
Parameters:
|
||
* eax = 65 - function number
|
||
* ebx = pointer to the image
|
||
* ecx = [size on axis x]*65536 + [size on axis y]
|
||
* edx = [coordinate on axis x]*65536 + [coordinate on axis y]
|
||
* esi = number of bits per pixel, must be 1,2,4,8,9,15,16,24 or 32;
|
||
* edi = pointer to palette (2 to the power esi colors 0x00RRGGBB);
|
||
ignored when esi > 8
|
||
* ebp = offset of next row data relative to previous row data
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* Coordinates of the image are coordinates of the upper left corner
|
||
of the image relative to the window.
|
||
* Format of image with 1 bit per pixel: each byte of image
|
||
(possibly excluding last bytes in rows), contains information on
|
||
the color of 8 pixels, MSB corresponds to first pixel.
|
||
* Format of image with 2 bits per pixel: each byte of image
|
||
(possibly excluding last bytes in rows), contains information on
|
||
the color of 4 pixels, two MSBs correspond to first pixel.
|
||
* Format of image with 4 bits per pixel: each byte of image
|
||
excluding last bytes in rows (if width is odd) contains
|
||
information on the color of 2 pixels, high-order tetrad
|
||
corresponds to first pixel.

* Format of image with 8 bits per pixel: each byte of image is
|
||
index in the palette.
|

* Format of image with 9 bits per pixel: array of one byte values;
|
||
each byte (8 bit) represents the intensity of gray for one pixel;
|
||
this format is equal to 8bpp without palette.

* Format of image with 15 bits per pixel: the color of each pixel
|
||
is coded as (bit representation) 0RRRRRGGGGGBBBBB - 5 bits per
|
||
each color.
|
||
* Format of image with 16 bits per pixel: the color of each pixel
|
||
is coded as RRRRRGGGGGGBBBBB (5+6+5).
|
||
* Format of image with 24 bits per pixel: the color of each pixel
|
||
is coded as 3 bytes - sequentially blue, green, red components.
|
||
* Format of image with 32 bits per pixel: similar to 24, but
|
||
one additional ignored byte is present. It's format is BGRX,
|
||
where X is the ignored byte.
|
||
* The call to function 7 is equivalent to call to this function
|
||
with esi=24, ebp=0.

======================================================================
|
||
================== Function 66 - work with keyboard. =================
|
||
======================================================================
|
||
The input mode influences results of reading keys by function 2.
|
||
When a program loads, ASCII input mode is set for it.
|
||
|
||
-------------- Subfunction 1 - set keyboard input mode. --------------
|
||
Parameters:
|
||
* eax = 66 - function number
|
||
* ebx = 1 - subfunction number
|
||
* ecx = mode:
|
||
* 0 = normal (ASCII-characters)
|
||
* 1 = scancodes
|
||
Returned value:
|
||
* function does not return value
|
||
|
||
-------------- Subfunction 2 - get keyboard input mode. --------------
|
||
Parameters:
|
||
* eax = 66 - function number
|
||
* ebx = 2 - subfunction number
|
||
Returned value:
|
||
* eax = current mode
|
||
|
||
------------ Subfunction 3 - get status of control keys. -------------
|
||
Parameters:
|
||
* eax = 66 - function number
|
||
* ebx = 3 - subfunction number
|
||
Returned value:
|
||
* eax = bit mask:
|
||
* bit 0 (mask 1): left Shift is pressed
|
||
* bit 1 (mask 2): right Shift is pressed
|
||
* bit 2 (mask 4): left Ctrl is pressed
|
||
* bit 3 (mask 8): right Ctrl is pressed
|
||
* bit 4 (mask 0x10): left Alt is pressed
|
||
* bit 5 (mask 0x20): right Alt is pressed
|
||
* bit 6 (mask 0x40): CapsLock is on
|
||
* bit 7 (mask 0x80): NumLock is on
|
||
* bit 8 (mask 0x100): ScrollLock is on
|
||
* bit 9 (mask 0x200): left Win is pressed
|
||
* bit 10 (mask 0x400): right Win is pressed
|
||
* other bits are cleared
|
||
|
||
-------------- Subfunction 4 - set system-wide hotkey. ---------------
|
||
When hotkey is pressed, the system notifies only those applications,
|
||
which have installed it; the active application (which receives
|
||
all normal input) does not receive such keys.
|
||
The notification consists in sending event with the code 2.
|
||
Reading hotkey is the same as reading normal key - by function 2.
|
||
Parameters:
|
||
* eax = 66 - function number
|
||
* ebx = 4 - subfunction number
|
||
* cl determines key scancode;
|
||
use cl=0 to give combinations such as Ctrl+Shift
|
||
* edx = 0xXYZ determines possible states of control keys:
|
||
* Z (low 4 bits) determines state of LShift and RShift:
|
||
* 0 = no key must be pressed;
|
||
* 1 = exactly one key must be pressed;
|
||
* 2 = both keys must be pressed;
|
||
* 3 = must be pressed LShift, but not RShift;
|
||
* 4 = must be pressed RShift, but not LShift
|
||
* Y - similar for LCtrl and RCtrl;
|
||
* X - similar for LAlt and RAlt
|
||
Returned value:
|
||
* eax=0 - success
|
||
* eax=1 - too many hotkeys (maximum 256 are allowed)
|
||
Remarks:
|
||
* Hotkey can work either at pressing or at release. Release
|
||
scancode of a key is more on 128 than pressing scancode
|
||
(i.e. high bit is set).
|
||
* Several applications can set the same combination;
|
||
all such applications will be informed on pressing
|
||
such combination.
|
||
|
||
-------------- Subfunction 5 - delete installed hotkey. --------------
|
||
Parameters:
|
||
* eax = 66 - function number
|
||
* ebx = 5 - subfunction number
|
||
* cl = scancode of key and edx = 0xXYZ the same as in subfunction 4
|
||
Returned value:
|
||
* eax = 0 - success
|
||
* eax = 1 - there is no such hotkey
|
||
Remarks:
|
||
* When a process/thread terminates, all hotkey installed by it are
|
||
deleted.
|
||
* The call to this subfunction does not affect other applications.
|
||
If other application has defined the same combination, it will
|
||
still receive notices.
|
||
|
||
--------------- Subfunction 6 - block the normal input. --------------
|
||
Parameters:
|
||
* eax = 66 - function number
|
||
* ebx = 6 - subfunction number
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* Blocking the normal keyboard input for installed hotkeys
|
||
* To emulate a mouse via the keyboard, the application MOUSEMUL
|
||
|
||
------------ Subfunction 7 - unlock the normal input. ----------------
|
||
Parameters:
|
||
* eax = 66 - function number
|
||
* ebx = 7 - subfunction number
|
||
Returned value:
|
||
* function does not return value

* esi = new y-size of the window
|
||
Returned value:
|
||
* function does not return value
|
||
Remarks:
|
||
* The value -1 for a parameter means "do not change"; e.g. to move
|
||
the window without resizing it is possible to specify edx=esi=-1.
|
||
* Previously the window must be defined by function 0.
|
||
It sets initial coordinates and sizes of the window.
|
||
* Sizes of the window are understood in sense of function 0,
|
||
that is one pixel less than real sizes.
|
||
* The function call for maximized windows is simply ignored.
|
||
* For windows of appropriate styles position and/or sizes can be
|
||
changed by user; current position and sizes can be obtained by
|
||
call to function 9.
|

======== Function 68, subfunction 24 - set exception handler. ========
|
||
======================================================================
|
||
Parameters:
|
||
* eax = 68 - function number
|
||
* ebx = 24 - subfunction number
|
||
* ecx = address of the new exception handler
|
||
* edx = the mask of handled exceptions
|
||
Returned value:
|
||
* eax = address of the old exception handler (0, if it was not set)
|
||
* ebx = the old mask of handled exceptions
|
||
Remarks:
|
||
* Bit number in mask of exceptions corresponds to exception number
|
||
in CPU-specification (Intel-PC). For example, FPU exceptions have
|
||
number 16 (#MF), and SSE exceptions - 19 (#XF).
|
||
* The current implementation ignores the inquiry for hook of 7
|
||
exception - the system handles #NM by its own.
|
||
* The exception handler is called with exception number as first
|
||
(and only) stack parameter. So, correct exit from the handler is
|
||
RET 4. It returns to the instruction, that caused the exception,
|
||
for faults, and to the next instruction for traps (see
|
||
classification of exceptions in CPU specification).
|
||
* When user handler receives control, the corresponding bit in
|
||
the exception mask is cleared. Raising this exception
|
||
in consequence leads to default handling, that is,
|
||
terminating the application in absence of debugger or
|
||
suspend with notification of debugger otherwise.
|
||
* After user handler completes critical operations, it can set
|
||
the corresponding bit in the exception mask with subfunction 25.
|
||
Also user handler is responsible for clearing exceptions flags in
|
||
FPU and/or SSE.

* otherwise eax = old value of activity for this signal (0/1)
|
||
Remarks:
|
||
* In current implementation only mask for user exception handler,
|
||
which has been previously set by subfunction 24,
|
||
is changed. Signal number corresponds to exception number.

====================== Function 69 - debugging. ======================
|
||
======================================================================
|
||
A process can load other process as debugged by set of corresponding
|
||
bit by call to subfunction 7 of function 70.
|
||
A process can have only one debugger; one process can debug some
|
||
others. The system notifies debugger on events occurring with
|
||
debugged process. Messages are written to the buffer defined by
|
||
subfunction 0.
|
||
Format of a message:
|
||
* +0: dword: message code
|
||
* +4: dword: PID of debugged process
|
||
* +8: there can be additional data depending on message code
|
||
Message codes:
|
||
* 1 = exception
|
||
* in addition dword-number of the exception is given
|
||
* process is suspended
|
||
* 2 = process has terminated
|
||
* comes at any termination: both through the system function -1,
|
||
and at "murder" by any other process (including debugger itself)
|
||
* 3 = debug exception int 1 = #DB
|
||
* in addition dword-image of the register DR6 is given:
|
||
* bits 0-3: condition of the corresponding breakpoint (set by
|
||
subfunction 9) is satisfied
|
||
* bit 14: exception has occurred because of the trace mode
|
||
(flag TF is set TF)
|
||
* process is suspended
|
||
When debugger terminates, all debugged processes are killed.
|
||
If debugger does not want this, it must previously detach by
|
||
subfunction 3.
|
||
|
||
All subfunctions are applicable only to processes/threads started
|
||
from the current by function 70 with set debugging flag.
|
||
Debugging of multithreaded programs is not supported yet.

* ebx = 9 - subfunction number
|
||
* ecx = thread identifier
|
||
* dl = index of breakpoint, from 0 to 3 inclusively
|

* dh = flags:
|
||
* if high bit is cleared - set breakpoint:
|
||
* bits 0-1 - condition:
|
||
* 00 = breakpoint on execution
|
||
* 01 = breakpoint on read
|
||
* 11 = breakpoint on read/write
|
||
* bits 2-3 - length; for breakpoints on exception it must be

||
the length (i.e. must be even for word breakpoints,
|
||
divisible by 4 for dword)
|
||
* if high bit is set - clear breakpoint
|
||
Returned value:
|
||
* eax = 0 - success
|
||
* eax = 1 - error in the input data
|
||
* eax = 2 - (reserved, is never returned in the current
|
||
implementation) a global breakpoint with that index is already set
|
||
Remarks:
|
||
* Process must be loaded for debugging (as is shown in
|
||
general description).
|
||
* Hardware breakpoints are implemented through DRx-registers of
|
||
the processor, all limitations results from this.
|
||
* The function can reinstall the breakpoint, previously set
|
||
by it (and it does not inform on this).
|
||
Carry on the list of set breakpoints in the debugger.
|
||
* Breakpoints generate debug exception #DB, on which the system
|
||
notifies debugger.
|
||
* Breakpoints on write and read/write act after
|
||
execution of the caused it instruction.

==== Function 70 - work with file system with long names support. ====
|
||
======================================================================
|
||
Parameters:
|
||
* eax = 70
|
||
* ebx = pointer to the information structure
|
||
Returned value:
|
||
* eax = 0 - success; otherwise file system error code
|
||
* some subfunctions return value in other registers too
|
||
General format of the information structure:
|
||
* +0: dword: subfunction number
|
||
* +4: dword: offset in file or folder
|
||
* +8: dword: higher part of offset or flags
|
||
* +12 = +0xC: dword: size of data
|
||
* +16 = +0x10: dword: pointer to data
|
||
* +20 = +0x14: ?: path - zero terminated string
|
||
or
|
||
* +20 = +0x14: byte: 0
|
||
* +21 = +0x15: dword: pointer to string
|
||
Case sensitivity depends on filesystem.
|
||
If a path not begins with '/', it is considered a relative.
|
||
To get or set the current folder, use the sysfunction 30.
|
||
'../' in the path means a lift by one folder relatively current folder.
|
||
To set the encoding, put at the start of the string a byte with next values:
|
||
* 1 = cp866
|
||
* 2 = UTF-16LE
|
||
* 3 = UTF-8
|
||
otherwise will be used cp866. In an absolute path
|
||
you may put this byte after the '/' or put an additional '/' before it.
|
||
Also, you may use the sysfunction 80.
|
||
Format of an absolute path:
|
||
/base/number/dir1/dir2/.../dirn/file,
|
||
where base/number identifies device, on which file is located:
|
||
* RD/1 = ramdisk
|
||
* FD/1 = first floppy drive,
|
||
FD/2 = second floppy drive
|
||
* HD0/x, HD1/x, HD2/x, HD3/x = hard drives accordingly on
|
||
IDE0 (Primary Master), IDE1 (Primary Slave),
|
||
IDE2 (Secondary Master), IDE3 (Secondary Slave);
|
||
x - partition number on the selected hard drive, starts from 1
|
||
* CD0/1, CD1/1, CD2/1, CD3/1 = same for cd
|
||
* SYS = system folder (encoding inaffected key),
|
||
second key may be set by sysfunction 30.3.
|
||
Examples:
|
||
* '/sys/example.asm',0
|
||
* '/rd/1/example.asm',0
|
||
* '/HD0/1/folder/file.txt',0
|
||
* '/hd2/2/pics/tanzania.bmp',0
|
||
* 2,'/',0,'sys','/',0,'F',0,'I',0,'L',0,'E',0,0,0
|
||
|
||
Available subfunctions:
|
||
* subfunction 0 - read file
|
||
* subfunction 1 - read folder
|
||
* subfunction 2 - create/rewrite file
|
||
* subfunction 3 - write to existing file
|
||
* subfunction 4 - set file size
|
||
* subfunction 5 - get attributes of file/folder
|
||
* subfunction 6 - set attributes of file/folder
|
||
* subfunction 7 - start application
|
||
* subfunction 8 - delete file/folder
|
||
* subfunction 9 - create folder
|
||
For CD-drives due to hardware limitations only subfunctions
|
||
0,1,5 and 7 are available, other subfunctions return error
|
||
with code 2.
|
||
At the first call of subfunctions 0,1,5,7 to ATAPI devices
|
||
(CD and DVD) the manual control of tray is locked due to caching
|
||
drive data. Unlocking is made when subfunction 4 of function 24
|
||
is called for corresponding device.

and the parent folder.
|
||
* The function allows also to read virtual folders "/", "/rd",
|
||
"/fd", "/hd[n]", thus attributes of subfolders are set to 0x10,
|
||
and times and dates are zeroed. An alternative way to get the

Returned value:
|
||
* function does not return neither value nor control
|
||
Remarks:
|
||
* If the process did not create threads obviously, it has only
|
||
one thread, which termination results in process termination.
|
||
* If the current thread is last in the process, its termination
|
||
also results in process terminates.
|
||
* This function terminates the current thread. Other thread can be
|
||
killed by call to subfunction 2 of function 18.

=========================== List of events ===========================
|
||
======================================================================
|
||
Next event can be retrieved by the call of one from functions 10
|
||
(to wait for event), 11 (to check without waiting), 23
|
||
(to wait during the given time).
|
||
These functions return only those events, which enter into a mask set
|
||
by function 40. By default it is first three,
|
||
there is enough for most applications.
|
||
Codes of events:
|
||
* 1 = redraw event (is reset by call to function 0)
|
||
* 2 = key on keyboard is pressed (acts, only when the window is
|
||
active) or hotkey is pressed; is reset, when all keys from
|
||
the buffer are read out by function 2
|
||
* 3 = button is pressed, defined earlier by function 8
|
||
(or close button, created implicitly by function 0;
|
||
minimize button is handled by the system and sends no message;
|
||
acts, only when the window is active;
|
||
is reset when all buttons from the buffer
|
||
are read out by function 17)
|
||
* 4 = reserved (in current implementation never comes even after
|
||
unmasking by function 40)
|
||
* 5 = kernel finished redrawing of the desktop background
|
||
* 6 = mouse event (something happened - button pressing or moving;
|
||
is reset at reading)
|
||
* 7 = IPC event (see function 60 -
|
||
Inter Process Communication; is reset at reading)
|
||
* 8 = network event (is reset at reading)
|
||
* 9 = debug event (is reset at reading; see
|
||
debug subsystem)
|
||
* 16..31 = event with appropriate IRQ
|
||
(16=IRQ0, 31=IRQ15) (is reset after reading all IRQ data)

* 2 = function is not supported for the given file system
|
||
* 3 = unknown file system
|
||
* 5 = file not found
|
||
* 6 = end of file, EOF
|
||
* 7 = pointer lies outside of application memory
|
||
* 8 = disk is full
|
||
* 9 = file system error
|
||
* 10 = access denied
|
||
* 11 = device error
|
||
* 12 = file system requires more memory
|
||
|
||
Application start functions can return also following errors:
|
||
* 30 = 0x1E = not enough memory
|
||
* 31 = 0x1F = file is not executable
|
||
* 32 = 0x20 = too many processes
