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.
