## 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, with the result that you must always use `send` and `recv` on sockets rather than the standard I/O operators.)
