[ee122] How should the program behave when user inputs Ctrl_D?

[Richard Schmidt]

Ctrl-C (An interrupt) will kill the process currently running. So there's no
way for you to say, "If user kills my program, do this."

Ctrl-D (EOF) However is a user-inputted key, and can be interpereted as the
macro <EOF>. Thus, if encountered your program will still be running after
it sees it, so it would be logical to close sockets and free up all your
malloc'd space before closing the process.

Then give a return value to your main function (mine is of type int so I
return 0 for success).
