=over =item send SOCKET,MSG,FLAGS,TO X =item send SOCKET,MSG,FLAGS Sends a message on a socket. Attempts to send the scalar MSG to the SOCKET filehandle. 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 C. Returns the number of characters sent, or the undefined value if there is an error. The C system call sendmsg(2) is currently unimplemented. See L for examples. Note the I: depending on the status of the socket, either (8-bit) bytes or characters are sent. By default all sockets operate on bytes, but for example if the socket has been changed using binmode() to operate with the C<:utf8> I/O layer (see L, or the C pragma, L), the I/O will operate on UTF-8 encoded Unicode characters, not bytes. Similarly for the C<:encoding> pragma: in that case pretty much any characters can be sent. =back
