=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 I, in which case it does a L syscall. Returns the number of characters sent, or the undefined value on error. The L syscall is currently unimplemented. See L for examples. Note that if the socket has been marked as C<:utf8>, C will throw an exception. The C<:encoding(...)> layer implicitly introduces the C<:utf8> layer. See L|/binmode FILEHANDLE, LAYER>. =back
