SDLNet_UDP_Close -- Shutsdown, disconnects, and closes the UDPsocket sock.
void SDLNet_UDP_Close(UDPsocket sock);
sock A valid UDPsocket. This can be a server or client type socket.
This shutsdown, disconnects, and closes the UDPsocket sock. After this, you can be assured that this socket is not in use anymore. You can reuse the sock variable after this to open a new connection with SDLNet_UDP_Open. Do not try to use any other functions on a closed socket, as it is now invalid.
Returns: nothing, this always succeeds.
// unbind all addresses on the UDPsocket channel 0 //UDPsocket udpsock; SDLNet_UDP_Close(udpsock); udpsock=NULL; //this helps us know that this UDPsocket is not valid anymore
