Hello. How does one locate the information about the CPU state before an
interrupt call while within the handler? More specifically, I want the
origional state of the registers (all of them) at the time the interrupt
was called, or at least to know how DJGPP stores them. It seems that
DJGPP gives each interrupt handler a new stack, and I don't WANT it to
do this, but I don't know how to avoid it, so I just want to be able to
access the stack of the location where the interrupt occured. Thanks.
