Subject: Interrupt overhead with DJGPP's extender

Message-ID: <31EC2DD4.7A94@ee.ubc.ca> (raw)
I understand that DJGPP programs run with the help of a DOS extender to
enable execution in a 32 bit protected address space under DOS. I'm
curious what overhead DJGPP's DOS extender imposes on programs in
general (I've been able to find no documentation on-line pertaining to
the functionality of DOS extenders).
In particular, I'd like to know what overhead is imposed by DJGPP's DOS
extender for interrupt handling (in GNAT Ada - although I can't see why
it should be any different in C).
