UDP/datagrams are different as each send/write will send a datagram; 
each receive/read will read a datagram. Your MTU size will limit the 
size of the datagram that you can use. The send/receive buffer sizes 
also come into play as datagrams may be discarded (on some platforms) if 
you attempt to send/write a datagram that is larger than the buffer 
size. Same thing the receive side. So the semantics are different and 
you probably won't want to do another send/write if there bytes 
remaining from the first send/write.
