3.4.9 SDLNet_UDP_RecvV

int SDLNet_UDP_RecvV(UDPsocket sock, UDPpacket **packetV)

sock

A valid UDPsocket.

packet

The packet to receive into.

Receive into a packet vector on the specified socket sock.
packetV is a NULL terminated array. Packets will be received until the NULL is reached, or there are none ready to be received.
This call is otherwise the same as SDLNet_UDP_Recv (see section 3.4.7 SDLNet_UDP_Recv).

Returns: the number of packets received. 0 is returned when no packets are received. -1 is returned on errors.

// try to receive some waiting udp packets //UDPsocket udpsock; //UDPpacket **packetV; int numrecv, i; numrecv=SDLNet_UDP_RecvV(udpsock, &packetV); if(numrecv==-1) { // handle error, perhaps just print out the SDL_GetError string. } for(i=0; i<numrecv; i++) { // do something with packetV[i] }
