The routines Keep
, GetIntVec
and SetIntVec
in
the Dos
unit do not even make sense on DJGPP (32 bit Dos
extender). If your program uses these, it is either a low-level Dos
utility for which porting to a 32 bit environment might cause bigger
problems (because the internal issues of DPMI become relevant which
are usually hidden by DJGPP), or it installs interrupt handlers
which will have to be thought about more carefully because of things
like locking memory, knowing about and handling the differences
between real and protected mode interrupts, etc. For these kinds of
things, we refer you to the DJGPP FAQ
(see DJGPP FAQ).
