I'm have a problem sending data as a file from one end of a socket to the other. What's happening is that both the server and client are trying to read the file so the file never gets sent. I was wondering how to have the client block until the server's completed reading the file sent from the client.

I have this working with raw packets using send and recv, but figured this was a cleaner solution...

Client:

1. connects to server creating socket connection
2. creates a file on socket and sends data
3. waits for file from server

Server:

1. waits for file from client

Complete interraction:

1. client sends data to server
2. server sends data to client
