Remarks: |
* Location and the sizes of the window are installed by the first call of |
this function and are ignored at subsequent; for change of location |
and/or of sizes already of created window use function 67. |
* If to use windows of appropriate styles, location and - or the sizes of |
the window can vary by the user. |
Current location and the sizes can be obtained by function 9. |
* The window should be located on the screen. If the transferred coordinates |
nd the sizes do not satisfy to this condition, appropriate coordinate |
(or, probably, is considered both) as zero, and if also it does not help, |
the appropriate size (or, probably, both) is installed in a size of the |
screen. |
* 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 style Y=3 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 also it does not help, the appropriate size |
(or, probably, both) is installed in a size of the screen. |

Further we shall designate xpos, ypos, xsize, ysize - values transmitted |
in ebx, ecx. The coordinates are resulted concerning the left upper corner |
of the window, which, thus, is set as (0,0), coordinate 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 and to all other functions. It means, |
that the real sizes on 1 pixel are more. |

======== Function 2 - receive the code of the pressed key. =========== |
============ Function 2 - get the code of the pressed key. =========== |
====================================================================== |
Takes away the code of the pressed key from the buffer. |
Parameters: |
* eax = 2 - number of the function |
* eax = 2 - function number |
Returned value: |
* if the buffer is empty, comes back eax=1 |
* If the buffer is nonblank, that comes back al=0, ah=code of the pressed key, |
high word of the register eax is set zero |
* If there is "hotkey", comes back |
al=2, ah=scancode of the pressed key (0 for direction keys), |
high word of the register eax contains a status of direction keys |
at the moment of pressing a hotkey |
* 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, high word of eax is 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 "hotkey". |
* By call of this function the application with the inactive window |
considers, that the buffer of the pressed keys is empty. |
* By default this function returns ASCII-codes; to switch to the mode |
scancode (and back) it is possible with usage of the function 66. |
However, the hotkey always come back as scancodes. |
* Ffind out, what keys correspond to what codes, is possible, having started |
the applications keyascii and scancode. |
* Scancodes come back directly by keyboard and are fixed; ASCII-codes turn |
out with usage of the conversion tables, which can be installed |
subfunction 2 functions 21 and to read subfunction 2 functions 26. |
* As a consequence, ASCII-codes take into account current keyboard layout |
(rus/en) as against scancodes. |
* The information only about those hotkeys acts which were defined by this |
stream subfunction 4 functions 66. |
* 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. |

Delays execution of the program on the given time. |
Parameters: |
* eax = 5 - number of the function |
* eax = 5 - function number |
* ebx = time in the 1/100 of second |
Returned value: |
* function does not return value |
Remarks: |
* The transmission ebx=0 does not transfer handle the following process |
and at all does not make any operations. If really it is required to |
transfer handle to the following process (to complete a current time |
slice), use subfunction of 1 function 68. |
* At current realization there will be an immediate return from the function, |
if the addition ebx with current value of the counter of time will call |
32-bit overflow. |
* 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. |
* At current implementation there will be an immediate return from |
the function, if the addition of ebx with current value of |
time counter will call 32-bit overflow. |

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. |

it can vary in the subsequent versions of a kernel. |
* It is possible to use subfunction 1, that on last step of termination |
the user himself has selected, that it is necessary. |
* It is not recommended to use value ecx=1 (to not irritate the user with |
excessive questions); to save ramdisk on a diskette it is possible by the |
function 16 (which admits specification, on which diskette to write), and |
to complete operation from the menu of an output(exit) it is possible |
already mentioned subfunction 1. |
* Do not rely on returned value by incorrect call, it can be |
changed in future versions of the kernel. |
* It is possible to use subfunction 1, that on the last step |
the user makes choice himself. |
* It is not recommended to use value ecx=1 (to not irritate the user |
with excessive questions); to save ramdisk on a floppy use |
function 16 (which admits specification, on which floppy to |

===== Function 18, subfunction 10 - minimize application window. ===== |
====================================================================== |
Minimizes the own window. |
Parameters: |
* eax = 18 - number of the function |
* ebx = 10 - number subfunction |
* eax = 18 - function number |
* ebx = 10 - subfunction number |
Returned value: |
* function does not return value |
Remarks: |
* The minimized window from the point of view of the function 9 saves |
a location and sizes. |
* Restoring of an application window occurs at activation subfunction 3. |
* Usually there is no necessity obviously to turn off/restore the window: |
turn off of the window is carried out by the system at pressing the button |
of minimization (which for windows with SKIN is defined automatically by |
function 0, for windows without SKIN it is possible to define by the |
function 8), restoring - application @panel. |
* The minimized window from the point of view of function 9 |
keeps position and sizes. |
* Restoring of an application window occurs at its activation by |
subfunction 3. |
* Usually there is no necessity to minimize/restire a window |
obviously: minimization of a window is carried out by the system |
at pressing the minimization button (for skinned windows |
it is defined automatically by function 0, |
for other windows it can be defined manually by function 8), |
restore of a window is done by the application '@panel'. |

automatically cancels the previous installation. However, at present any |
program it does not use. |

(installed bit permits notice on event) |
(set bit permits notice on event) |
Returned value: |
* function does not return value |
Remarks: |
* Mask by default (7=111b) permits notices about redraw, |
pressings keys and buttons. |
It is enough of it for the majority of the applications. |
* The events prohibited in a mask, are all same saved, if come; |
with events simply do not inform on them functions of operation. |
* Functions of operation with events take into account a mask on moment |
of function call, instead of on moment of arrival of message. |
* Default mask (7=111b) enables nofices about redraw, |
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. |

Remarks: |
* In case of backup of ports the error considers execution of one |
of conditions: |
* beginning address more than end address; |
* indicated range contains incorrect number of a port |
(correct - from 0 up to 0xFFFF); |
* limitation on a total number of the reserved areas - |
is exceeded the maximal 255 is admitted; |
* indicated range is intersected with one of earlier reserved |
* In case of release of ports the error considers attempt of release of |
a range, which was not wholly reserved by same function (with the same |
values ecx, edx) earlier. |
* At detection of an error (in both cases) any operations is not does. |
* At loading the system reserved behind itself ports 0.. 0xff, and at |
detection of COM-mouse - in addition range of COM-ports 0x3f0.. 0x3ff |
and/or 0x2f0.. 0x2ff. |
* At completion thread all ports, reserved by it are automatically free. |
* 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..0xff, and if |
COM-mouse is detected - additionally range of COM-ports |
0x3f0..0x3ff and/or 0x2f0..0x2ff. |
* When a thread terminates, all reserved by it ports |
are freed automatically. |

=========== Function 50 - installation of form of window. ============ |
=================== Function 50 - set window shape. ================== |
====================================================================== |
The usual windows represent rectangles. With the help of this function the |
window can add the arbitrary form. The form sets by a set of points inside |
a framing rectangle concerning to the window. Location and the sizes of |
a framing rectangle are set by the function 0 and vary with the function 67. |
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. |
|
----------- Installation of data with information on form ------------ |
--------------------------- Set shape data --------------------------- |
Parameters: |
* eax = 50 - number of the function |
* ebx = 0 - number subfunction |
* ecx = pointer on the given forms (array byte 0/1) |
* 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 |
|
---------------- Installation of a scale of given form --------------- |
-------------------------- Set shape scale --------------------------- |
Parameters: |
* eax = 50 - number of the function |
* ebx = 1 - number subfunction |
* ecx sets a scale: each byte of the data defines |
(2^scale) * (2^scale) of pixels |
* 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: |
* Scale is by default equal 0 (scaling factor 1). If in the given form |
of one byte corresponds to one pixel, the scale is possible to not install. |
* Let's designate xsize = width of the window (in pixels), ysize = height; |
pay attention, that they on unit are more, than installed by |
* 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 a scale xsize and ysize should be divided on 2^scale. |
* Byte of the data on offset a should be 0/1 and defines an accessory to |
the window of a square with the side 2^scale (at scale=0 we receive |
a pixel) and coordinates of the left upper corner |
* 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)) |
* Size of the data: (xsize shr scale)*(ysize shr scale). |
* Data should be present at memory and not vary after installation |
of the form. |
* System views the data on the form at everyone redraw of the window |
by the function 0. |
* Call subfunction 0 with the zero pointer results in return to the |
rectangular form. |
* 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 58, subfunction 0 - read file/folder. =========== |
====================================================================== |
Parameters: |
* eax = 58 |
* ebx = pointer on information structure |
Format of information structure: |
* +0: dword: 0 = number subfunction |
* +4: dword: number of block for reading (beginning from 0) |
* +8: dword: éuantity blocks for reading |
* +12 = +0xC: dword: pointer on the buffer, where the data will be written |
* +16 = +0x10: dword: pointer on the buffer for system operation |
* ebx = pointer to the information structure |
Format of the information structure: |
* +0: dword: 0 = subfunction number |
* +4: dword: first block to read (beginning from 0) |
* +8: dword: amount of blocks to read |
* +12 = +0xC: dword: pointer to buffer for data |
* +16 = +0x10: dword: pointer to buffer for system operations |
(4096 bytes) |
* +20 = +0x14: ASCIIZ-name of the file, the rules of creation of names |
are indicated in the common description |
* +20 = +0x14: ASCIIZ-name of file, the rules of names forming are |
given in the general description |
Returned value: |
* eax = 0 - successfully, differently error code of a file system |
* ebx = file size (in bytes) or |
-1=0xffffffff, if the file is not retrieved |
* eax = 0 - success, otherwise file system error code |
* ebx = file size (in bytes) or -1=0xffffffff, if file was not found |
Remarks: |
* Size of block - 512 bytes. |
* Block size is 512 bytes. |
* This function is obsolete, for reading files use subfunction 0 |
functions 70, for reading folders - subfunction of 1 function 70. |
* Function allows to read contents of a folder. From file systems is |
supported only FAT. The format of a FAT-folder is described in any |
documentation on FAT. |
* Size of a folder is defined on a size of a chain of clusters in FAT. |
* If the file was terminated earlier, than last requested block was read, |
the function will read, how many can, then will return eax=6 (EOF). |
* Function allows to read root folders /rd/1, /fd/x, /hd [n] /x, but |
in first two cases the current implementation does not follow the |
installed rules: |
of function 70, for reading folders - subfunction 1 of |
function 70. |
* Function can read contents of a folder. Only FAT file system is |
supported. The format of FAT-folder is described |
in any FAT documentation. |
* Size of a folder is determined by size of FAT clusters chain. |
* If file was ended before last requested block was read, |
the function will read as many as it can, and after that return |
eax=6 (EOF). |
* Function can read root folders /rd/1,/fd/x,/hd[n]/x, but |
in the first two cases the current implementation does not follow |
to the declared rules: |
for /rd/1: |
* if 0 blocks for reading are indicated, it is considered, |
that is requested 1; |
* if is requested more than 14 blocks or the initial block is not |
less 14, comes back eax=5 (not found) and ebx =-1; |
* size of the root ramdisk = 14 blocks, 0x1C00=7168 bytes; but comes |
back ebx=0 (except for a case of the previous item); |
* strangely enough, it is possible to read 14 block (there, generally |
speaking, garbage - I remind, the score carries on with 0); |
* if one block with number, not smaller 14 was requested even, |
comes back eax=6 (EOF); differently eax=0. |
for /fd/x: |
* if the initial block is not less 14, comes back eax=5 (not found) |
and ebx=0; |
* by the way speaking, the format FAT12 admits diskettes with a size |
of the root less or more than 14 blocks; |
* checks of length is not done; |
* if it was possible to read given with a diskette, comes back eax=0, |
ebx=0; otherwise eax=10 (access denied), ebx =-1. |
* Function handles reading special folders /, /rd, /fd, /hd [n]; but the |
result does not correspond expected (on operation with usual |
files/folders), does not follow the installed rules, can vary in the |
following versions of a kernel and consequently is not described. |
For obtaining the information about the equipment use subfunction 11 |
functions 18 or read appropriate folders subfunction of 1 function 70. |
* if one want to read 0 blocks, function considers, |
that he requested 1; |
* if one requests more than 14 blocks or starting block is |
not less than 14, function returns eax=5 (not found) è ebx=-1; |
* size of ramdisk root folder is 14 blocks, |
0x1C00=7168 áàéò; but function returns ebx=0 |
(except of the case of previous item); |
* strangely enough, it is possible to read 14th block (which |
generally contains a garbage - I remind, the indexing begins |
from 0); |
* if some block with the number not less than 14 was requested, |
function returns eax=6(EOF); otherwise eax=0. |
For /fd/x: |
* if the start block is not less than 14, function returns |
eax=5 (not found) and ebx=0; |
* note that format of FAT12 allows floppies with the root size |
more or less than 14 blocks; |
* check for length is not performed; |
* if data was successful read, function returns |
eax=0,ebx=0; otherwise eax=10 (access denied), ebx=-1. |
* The function handles reading of special folders /,/rd,/fd,/hd[n]; |
but the result does not correspond to expected (on operations with |
normal files/folders), does not follow the declared rules, |
may be changed in future versions of the kernel and consequently |
is not described. To obtain the information about the equipment |
use subfunction 11 of function 18 or |
read corresponding folder with subfunction 1 of function 70. |

it only for hard disks. |
* File should already exist (differently comes back 5, not found). |
For creation of files use subfunction 1. |
* If the initial position is more than a file size, comes back eax=6 (EOF). |
If the finite position is more than a file size, the file extends. |
* Code of processing of data writing for the hard disk interpretes zero |
value of a field +8 as the instruction of a truncation of the file |
up to a size indicated in a field +4. However code of processing of |
58-th function locks this possibility for the applications, at once |
returning handle (with eax=0) in case of a zero size. |
* Ramdisk and floppies do not support this function, it is only |
for hard disks. |
* File must already exist (otherwise function returns 5, not found). |
To create files use subfunction 1. |
* If the starting position is greater than file size, the function |
returns eax=6(EOF). If the end position is greater than file size, |
file is extended. |
* The code of write processing for hard disk interpretes zero |
value of the field +8 as the instruction to truncate the file to |
the size, given in the field +4. However the code of processing |
58th function blocks this possibility for applications by |
immediate return (with eax=0) in the case of zero size. |

Remarks: |
* Be not surprised to strange layout of 4-th returned parameter - when this |
code was written, at system calls to the application the registers eax, |
ebx, ecx (from pushad-structure transmitted as argument to the system |
function) came back only. Now it is corrected, so, probably, it is |
meaningful to return a cluster size in edx, while this function have |
not begun to use |
* Generally still exists subfunction 11 functions 18, returning the |
information on a file system. Under the extended table of a disk |
subsystem it is possible to define a cluster size (there it is stored |
in sectors) and total number of clusters for hard disks. |
* Be not surprised to strange layout of 4th returned parameter |
- when this code was writing, at system calls application got |
only registers eax,ebx,ecx (from pushad-structure transmitted |

probably, it is meaningful to return cluster size in edx, while |
this function is not used yet. |
* There exists also subfunction 11 of function 18, |
which returns information on file system. From the full table |
of disk subsystem it is possible to deduce cluster size (there |
it is stored in sectors) and total number of clusters |
for hard disks. |

Remarks: |
* Function is used only in the application systrace. It is rather difficult |
to present a situation, in which this application or this function are |
really useful, and all system calls for support of this function are a |
little decelerated (though and not strongly)... |
* In this connection there is a sentence support of this function from |
a kernel to remove absolutely, together with the application systrace. |
* Information on system calls is saved in system ring buffer |
on 0x10 of inputs. |
This function simply copies the indicated size given from the mentioned |
buffer to the indicated address. |
* To what from inputs in the buffer corresponds to last call, it is possible |
to define on value eax, namely, |
input (eax and 0xF) (on offset (eax and 0xF) *0x40). |
* In current implementation the seldom meeting problems of |
unsynchronization are possible, when about some calls the |
information becomes outdated. |
* Under the system buffer the page, 4 KB is allocated. |
Size of an input = 64 bytes. |
Why 16 inputs - not clearly are used only. |
* Value esp at moment of system call by this function cannot be found out. |
* Checks of a correctness edx in current implementation is not done. |
* The function is used only in the application 'systrace'. |
It is rather difficult to imagine a situation, in which |
this application or this function are really useful; |
and all system calls for support of this function are a little |
decelerated (though not strongly)... |
* So there is a proposition to delete from the kernel |
support of this function, together with application 'systrace'. |
* The information on system calls saves in the system |
ring buffer with 0x10 entries. |
This function simply copies the given size of data |
from this buffer to the given address. |
* One can determine, which entry in the buffer corresponds to |
last system call, by value of eax, namely, it is the entry |
(eax and 0xF) (at offset (eax and 0xF)*0x40). |
* In the current implementation there can be the seldom |
meeting problems of unsynchronization, when the information |
on some calls becomes outdated. |
* Under the system buffer one page, 4Kb, is allocated. |
Size of an entry = 64 bytes. Why only 16 entries are used, |
is not clearly. |
* The value of esp at the moment of system call cannot |
be determined by this function. |
* The current implementation does not check edx for correctness. |

====================================================================== |
Data of graphics screen are accessible to program (area of memory, which purely |
also displays contents of screen) directly without calls of system functions |
through the selector gs: |
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] |
will place in eax first dword of buffer containing information on colour |
of left upper point (and, probably, colour of several following). |
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 operation in modes VESA c LFB will install colour of left upper point |
(and, probably, colour of several following). |
Interpretations given of the graphics screen need knowledge of some parameters, |
which come back by this function. |
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: |
* Parameters of a graphics very seldom vary at system operation, namely, |
only in cases, when the user works with the program VRR. |
* At change of videomode the system redraw all windows |
(event with the code 1) and redraw a background (event 5). |
Same events occur and in other cases, which meet much more often, |
than change of videomode. |
* By operation in videomodes with LFB the selector gs specifies on purely |
LFB, so reading / writing on gs result directly in change of contents of |
the screen. By operation in videomodes without LFB gs specifies some area |
of the given kernel, and all functions of output on the screen honesty |
fulfil double operation on writing directly on the screen and on |
writing in this buffer. In result at reading contents of this buffer the |
results correspond to contents of the screen (with, generally speaking, |
large colour permission), and writing ignored. |
Exception is the mode 320*200, for which in main loop system thread the |
upgrade of the screen is fulfilled according to movements |
of a mouse pointer. |
* Graphics parameters changes very seldom at work, |
namely, only in cases, when user works with the application VRR. |
* 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 debugging board. ============== |
============== Function 63 - work with the debug board. ============== |
====================================================================== |
Debugging board represents the system buffer (on 512 bytes), in which any |
program can write (generally speaking, arbitrary) data and from which other |
program can these data read. |
There is an agreement, according to which written given - text strings |
interpreted as of the debug message on a course of execution of the program. |
The kernel in the defined situations also writes to board of debugging of the |
item of information about execution of some functions; under the agreement of |
the message of a kernel start with the prefix " K: ". |
For review of board of debugging the application board is created which reads |
out the data from the buffer and displays them in the window. board understands |
a sequence of codes 13,10 as transition on new string |
Character with the zero code at the end of string is not mandatory, |
The debug board is the global system buffer (with the size |
512 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. |
As has appeared of the debugger necessity of board of debugging a little has |
decreased, as the debugger allows completely to inspect a course of execution |
of the program, and for this purpose it is not required of any efforts on the |
part of the program. Nevertheless in many cases the board of debugging |
continues to remain useful. |
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. |

(will return eax=10, access denied). |
* If file was ended before last requested block was read, |
the function will read as many as it can, and after that return |
eax=6 (EOF). |
* The function does not allow to read folder (returns eax=10, |

data contain garbage. |
* If files in folder were ended before requested number was read, |
the function will read as many as it can, and after that return |
eax=6 (EOF). |
* Any folder on the disk, except for root, contains two special |
inputs(entrances) "." And "..", identifying accordingly folder |
and parent folder. |
* Function allows also to read virtual folders "/", "/rd", "/fd", |
"/hd [n] ", thus the attributes subfolders rely equal 0x10, and the times |
and dates are unset. An alternate way of obtaining of the information |
about the equipment - subfunction 11 functions 18 |
entries "." and "..", identifying accordingly the folder itself |
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 |
equipment information - subfunction 11 of function 18. |

applications of. |
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: |

* 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 the function 2 |
* 3 = button is pressed, defined earlier by function 8(or buttons of closing, |
created implicitly by function 0 is pressed; the button of minimization is |
handled by the system and about it of the message does not come; acts, only |
when the window is active; is reset, when all buttons from the buffer are |
read out by the function 17) |
* 4 = reserved (in current implementation never comes even at unmasking |
by the function 40) |
* 5 = redraw the background of a desktop (is reset automatically after |
redraw, so if in time redraw of a background the program does not wait |
and does not check event, this event it will not remark) |

(16=IRQ0, 31=IRQ15) (is reset at reading all data IRQ) |
* 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) |
