3.5.2 SDLNet_ResizePacket

int SDLNet_ResizePacket(UDPpacket *packet, int size)

packet

A pointer to the UDPpacket to be resized.

size

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

Resize a UDPpackets data buffer to size bytes. The old data buffer will not be retained, so the new buffer is invalid after this call.

Returns: the new size of the data in the packet. If the number returned is less than what you asked for, that's an error.

// Resize a UDPpacket to hold 2048 bytes of data //UDPpacket *packet; int newsize; newsize=SDLNet_ResizePacket(packet, 2048); if(newsize<2048) { printf("SDLNet_ResizePacket: %s\n", SDLNet_GetError()); // perhaps do something else since you didn't get the buffer you wanted } else { // do stuff with the resized packet }
