Lookup PID from Port.

[Jason8]

Does anyone know if you can lookup the PID that owns a socket (based
on port number) programmatically? I know most systems have LSOF for
this but I'd like it to be more portable and not call an external
program.

I can't think off-hand of a library that does this, strange to say. I'd
advise you to have a look at the source code to netstat on your platform
(e.g. on Debian it's in the net-tools package) and pick out the bits
where it does the relevant magic.

The C language itself doesn't define PIDs, sockets, or port numbers.

Try comp.unix.programmer.
