Function 0202 - Get Processor Exception Handler Vector

PMODE/W API

This function Returns the address of the current protected mode exception handler for the specified exception number.

In:
   AX     = 0202h
   BL     = exception number (00h-1fh)
Out:
   if successful:
     carry flag clear
     CX:EDX = selector:offset of exception handler
   if failed:
     carry flag set

Notes:
PMODE/W handles exceptions under clean/XMS/VCPI environments. Under a DPMI environment, exception handling is provided by the DPMI host.

PMODE/W only traps exceptions 0 through 14. The default behavior is to terminate execution and do a debug dump. PMODE/W will terminate on exceptions 0, 1, 2, 3, 4, 5, and 7, instead of passing them down to the real mode handlers as DPMI specifications state.
