This is exactly what read() on a socket is supposed to do; wait until there's some data recieved, then return it. When the client closes the connection, indicate EOF.

In what way do you want read() to return 0 earlier? If you want it do do that the first time there's no data available, then you need to set the socket to non-blocking. Note that in that case you'll need some extra logic to determine when and how you have read enough data, and you'll need to add a select() call to wait for motre data.
