Hope you can help - the program you attached doesn't compile under
FC4.. with the following:
digibox.c:46: warning: incompatible implicit declaration of built-in
function âexitâ
For a start, they're just warnings, so it should have actually given
you an exe. at the and. Put the exit() calls back, and try replacing
the first (don't nkow how I ended up with 2) 'unistd.h' #include with
'stdlib.h'.
Failing that, do 'man 2 exit' and see what it says you need to
include for exit().
P.S.
this is the part where it segfaults (first time I've ever done a gdb!)
