Ok. Maybe you just want to trap all __dpmi_int calls. In that case,
just try

#define __dpmi_int(X, Y) \
printf("Interrupt %d\n", i);\
__dpmi_int(X, Y)

But if you want to catch all interrupts (including h/w interrupts), like
Eli said, you *must* hook all interrupts (which doesn't sound like
a sensible thing to do).
