TCPIP_UDP_DestinationIPAddressSet Function

bool TCPIP_UDP_DestinationIPAddressSet(UDP_SOCKET hUDP, IP_ADDRESS_TYPE addType, IP_MULTI_ADDRESS* remoteAddress); 

• true - Indicates success
• false - Indicates failure:
• invalid socket
• invalid socket address type
• socket is of broadcast type

• It sets the IP destination address This allows changing the IP destination address dynamically.

The call will fail if the socket was previously set to broadcast using the TCPIP_UDP_OptionsSet call. TCPIP_UDP_OptionsSet takes precedence. The call will fail if remoteAddress is 0. The destination IP address will not be changed.

UDP initialized UDP socket should have been opened with TCPIP_UDP_ServerOpen()/TCPIP_UDP_ClientOpen()(). hUDP - valid socket remoteAddress - valid address pointer
