send
send - send a message over a socket
send SOCKET,MSG,FLAGS,TO
send SOCKET,MSG,FLAGS
Sends a message on a socket. Takes the same flags as the system call
of the same name. On unconnected sockets you must specify a
destination to send TO, in which case it does a C sendto(). Returns
the number of characters sent, or the undefined value if there is an
error.
See ``UDP: Message Passing'' for examples.
