======================================================================
====== Function 68, subfunction 15 - set new exceptions handler ======
====== Function 68, subfunction 15 - set FPU exception 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.
Deleted (in current implementation only 0 is returned).
Using subfunctions 24, 25 is true.
 
======================================================================
============= Function 68, subfunction 16 - load driver. =============
3694,19 → 3671,10
* Previously one must obtain driver handle by subfunction 16.
 
======================================================================
==== Function 68, subfunction 18 - change state of signal activity ===
====== Function 68, subfunction 18 - set SSE exception handler. ======
======================================================================
Parameters:
* eax = 68 - function number
* ebx = 15 - subfunction number
* ecx = signal number
* edx = value of activity (0/1)
Returned value:
* 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.
Deleted (in current implementation only 0 is returned).
Using subfunctions 24, 25 is true.
 
======================================================================
=============== Function 68, subfunction 19 - load DLL. ==============
3747,6 → 3715,50
the new and old sizes.
 
======================================================================
====== Function 68, subfunction 24 - set new exceptions handler ======
======================================================================
Parameters:
* eax = 68 - function number
* ebx = 24 - 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 25 - change state of signal activity ===
======================================================================
Parameters:
* eax = 68 - function number
* ebx = 25 - subfunction number
* ecx = signal number
* edx = value of activity (0/1)
Returned value:
* 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.
