I want to install an interrupt handler via the dpmi-functions.
As I have not much experience in programing assembler interrupt
routines, I would be pleased if anyone could tell me where I can find
some documentations or tutorials about  protected mode interrupts and
the dpmi-function.

The dpmi-specification does not say anything special about memory
locking for interrupts. Do I have only to lock the data area which is
touched by the int-handler ?
Or do I have also to lock the code area of the int-handler ???
Does an int-function only differ from an ordinery function by the fact
that it ends with a sti and an iret ?
