3.5.1 SDLNet_AllocPacket

UDPpacket *SDLNet_AllocPacket(int size)

size

Size, in bytes, of the data buffer to be allocated in the new UDPpacket.
Zero is invalid.

Create (via malloc) a new UDPpacket with a data buffer of size bytes.
The new packet should be freed using SDLNet_FreePacket when you are done using it.

Returns: a pointer to a new empty UDPpacket. NULL is returned on errors, such as out-of-memory.

// create a new UDPpacket to hold 1024 bytes of data UDPpacket *packet; packet=SDLNet_AllocPacket(1024); if(!packet) { printf("SDLNet_AllocPacket: %s\n", SDLNet_GetError()); // perhaps do something else since you can't make this packet } else { // do stuff with this new packet // SDLNet_FreePacket this packet when finished with it }
