====== 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

Parameters:
