Multithreaded chat server/client written in C

After compiling, there will be two executables: server and client Run the server by doing: ./server [Port] or just ./server

The default port is 9999

Run the client by doing: ./client [Username] [Host] [Port]

The client is mostly the same except for the existence of a static global variable (sorry). The client's socket fd to the server is global so the client's interrupt handler can send a message to the server telling it that the client has disconnected.
