How to open and use a socket in C?

Question

I would like to know the simplest and most effective way to open and write data to a socket in the C programming language for network programming.

Answer 1

Reading and writing from basic sockets is not any harder than reading and writing normal files (just use recv instead of read and send instead if write). Things get a little trickey when you need to open a socket. The reason for that is because there are many different ways to communicate using sockets (TCP, UDP, etc).
