Each UDP socket is able to use the size for sending data, even if total pages of UDP sockets exceed udp_mem pressure. Socket options To set or get a UDP socket option, call getsockopt(2) to read or setsockopt(2) to write the option with the option level argument set to IPPROTO_UDP. Unless otherwise noted, optval is a pointer to an int

Binds the local address and port for the socket. For a client socket, it is recommended to use port 0 to let the platform pick a free port. Once the bind operation completes successfully, onReceive events are raised when UDP packets arrive on the address/port specified -- unless the socket is paused.
