send
See the current Perl documentation for send.
Here is our local, out-dated (pre-5.6) version:
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.
