DOS/32 Advanced DOS Extender - Programmer's Reference

5.03 - Mouse function 0014h - Exchange Interrupt Subroutines


In: AX = 0014h
ECX = call mask
ES:EDX = far pointer to interrupt routine
Out: ECX = call mask of previous interrupt routine
ES:EDX = far pointer of previous interrupt routine


a) This function will use a real mode callback that was allocated by the DOS/32 Advanced at startup to pass the control from real mode mouse handler to your protected mode interrupt handler.

b) Calling this function with zero values in ES:EDX (0000:00000000h) will uninstall your protected mode interrupt handler.
