ResolveUDPAddr returns an address of UDP end point. The network must be a UDP network name. If the host in the address parameter is not a literal IP address or the port is not a literal port number, ResolveUDPAddr resolves the address to an address of UDP end point. Otherwise, it parses the address as a pair of literal IP address and port number.
