SDLNet_ResizePacket
Name
SDLNet_ResizePacket -- resize a UDP packet.
Synopsis
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.
Description
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.
Return Value
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.
Example
// 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
}
