What do you mean by:
"how can you be guaranteed that the server will even get the whole size?"

The actual size variable in the header, or the packet data?

The size variable should be a byte or a word, dont think you would need more than that. So you read until you got it.

Then, when you got the size of the data, you keep reading until you have received that amount of bytes, or a timeout occurs.

Thats how I would do it anyway.

Yeah, that''s what I ended up doing. I just wasn''t thinking clearly.

For simplicity I just made a function which calculated packet size from the packet type, which is the first byte in each packet. Now when a single byte is received my program knows what kind of packet it''s dealing with _and_ how big it is.

Thanks for your help.

And yeah, I''m rileyriley from uniball.

Yea, that makes sense. The only packet I can think of that really
needs variable length is a chatmessage packet.

Cheers!
