There are quite a few things wrong with your example, such as: using

instead of using select() or poll(). There are probably more problems,
I only glanced over it.

You should run to your nearest library, borrow and read the entirety
of W. Richard Stevens' "Advanced Programming in the UNIX Environment"
before writing another line of code. Also, check out libevent:
