Synopsis

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.
