The message is printed, but the three hashes (###) are never print? Why? The program seems to block on read(). Here i do just printing, but what i need to do is to buffer the whole message and then process it.

Typically, your application level logic needs to know in advance how much to read, or reads until a certain terminator is received, or the other end gracefully closes or shuts down the socket.
(Non-blocking I/O is something else entirely - it allows you to do other things whilst reading from sockets efficiently in a single thread, but it doesn't solve the problem of determining when you've finished reading from a socket, which is your problem.)
