send
send socket, msg, flags, [dest]
Sends a message msg on a
socket. It takes the same flags as the system call of the same
name (see send(2)). On
unconnected sockets, you must specify a destination
dest to send to, in which case send works like sendto(2). The function returns the
number of bytes sent, or the undefined value if there is an error.
On error, it puts the error code into $!.
Some non-Unix systems improperly treat sockets as different
objects than ordinary file descriptors, which means that you must
always use send and recv on sockets rather than the standard
I/O operators.
