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]
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
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
3613,29 → 3613,47
or subfunction 20.

======== Function 68, subfunction 14 - wait for driver notify. =======
===================== Function 68, subfunction 14 ====================
====== Waiting delivering of signal from another program/driver ======
======================================================================
Parameters:
* eax = 68 - function number
* ebx = 14 - subfunction number
* ecx = pointer to the buffer for information (8 bytes)
* ecx = pointer to the buffer for information (24 bytes)
Returned value:
* buffer pointed to by ecx contains the following information:
* +0: dword: constant EV_INTR = 1
* +4: dword: driver data
Remarks:
* The current implementation at wait time uses "heavy" operations
of task switch.
* +0: dword: identifier for underlying data of signal
* +4: data of signal (20 bytes), format of which is defining by
first dword
======================================================================
====== Function 68, subfunction 15 - set FPU exception handler. ======
====== Function 68, subfunction 15 - set new exceptions handler ======
======================================================================
Parameters:
* eax = 68 - function number
* ebx = 15 - subfunction number
* ecx = address of the new exception handler
* edx = the mask of processing exceptions
Returned value:
* eax = address of the old exception handler (0, if it was not set)
* ebx = the old mask of exception handler
Remarks:
* Bit number in mask of exceptions is correspond to exception number
by CPU-specification (Intel-PC). For example, FPU-exception have
number 16 (#MF), and SSE-exception - 19 (#XF)
* The current implementation ignore the inquiry for hook of 7
exception - system process #NM by one's own.
* User handler get exception number in stack parameter. So, correct
exit from handler is: RET 4. Return from handler is to the same
instruction, that was cause the exception
* When control is transfering to user handler, corresponding bit in
exception mask is clearing. Rising this exception in consequence
- reduce to default-handling. Exactly: terminating the application,
or suspending with debug-notify to owner.
* After completion of critical operations in user handler, it may be
rising corresponding bit in exception mask by using subfunction 18
Clearing exceptions flags in FPU and/or XMM modules - is
responsibility of user handler too.
======================================================================
============= Function 68, subfunction 16 - load driver. =============
3676,14 → 3694,19
* Previously one must obtain driver handle by subfunction 16.
======================================================================
====== Function 68, subfunction 18 - set SSE exception handler. ======
==== Function 68, subfunction 18 - change state of signal activity ===
======================================================================
Parameters:
* eax = 68 - function number
* ebx = 15 - subfunction number
* ecx = address of the new exception handler
* ecx = signal number
* edx = value of activity (0/1)
Returned value:
* eax = address of the old exception handler (0, if it was not set)
* eax = value of old activity for this signal (0/1)
Remarks:
* In current implementation, it is changed only exception mask for
user exception handler, wich was previously set by subfunction 15.
At that, number of signal correspond to exception number.
======================================================================
=============== Function 68, subfunction 19 - load DLL. ==============

and at arrival of new message the system will wait.
For synchronization frame all work with the buffer by operations

* Data in the buffer are considered as array of items with variable
length - messages. Format of a message is explained in
general description.
