If I'm not mistaken, you provide recv () with a pointer to the buffer
and the buffer size you want the fresh data to be stored in, and it
returns the amount of bytes.
The best way to see whether a socket still has data available is to
use a select ()-based event handling system, such as the Reactor. If
an event arrives on the socket, and you have read 0 or -1 bytes, you
know that the connection has been/should be closed.
I hope this helps.
