socket

Server Socket

• create a socket - Get the file descriptor!
• bind to an address -What port am I on?
• listen on a port, and wait for a connection to be established.
• accept the connection from a client.
• send/recv - the same way we read and write for a file.
• shutdown to end read/write.
• close to releases data.

Client Socket

• create a socket.
• bind* - this is probably be unnecessary because you're the client, not the server.
• connect to a server.
• send/recv - repeat until we have or receive data
• shutdown to end read/write.
• close to releases data.
