Sure. First, figure out what system calls/library calls you would need to do
that in C. Second, call those routines from Ada. Ada can mimic C's calling
conventions, and thus can call any subroutine that was intended for C that can
be linked in.

If you don't know how to do this in C either, what you really have is a Unix
question, not an Ada question. We might be able to help with that too (if you
tell us what Unix flavor/platform you have), or you could ask in an
appropriate Unix newsgroup.
