You might try to have a look at the select() call. I think it meets your
requirements. Additionally you could create an exclusive thread for the
network stuff.
Or set your socket to nonblocking mode via ioctl() (I guess you're
programming with Linux ??) and poll for data in a loop (not recommened
though since it hogs the cpu).
