Suppose I want to write a DOS (DPMI) program to run Linux apps.
This program must handle the Linux syscalls (INT 80h).

I can write a DJGPP program that issues and handles software
interrupts, but how do I get the values of the registers
when the INT instruction occured? Are they pushed onto the
stack, available to the handler function?
