Off-topic for comp.lang.c

Please ask in comp.unix.programmer, where it's more appropriate,
assuming you're talking about POSIX bind.
(I'm setting follow-ups there)

You can examine errno.

if(bind(...) == -1) {
if(errno == EADDRINUSE) { /* ... */ }
else if(...)
}

The errors are listed in the following link, under ERRORS.
