int size);UDPpacket * SDLNet_AllocPacket(
the maximum number of bytes of payload this packet will contain.

When done with this packet, you can free it with SDLNet_FreePacket. Packets can be reused multiple times; you don't have to allocate a new one for each piece of data you intend to send.
You can allocate multiple packets at once with SDLNet_AllocPacketV.
