[1] recv() is a blocking function. blocks until the complete buffer is read. i don't find a function to get the number of readable bytes, so SDL_net seems to be useless or only usefull with workarounds. due to the need for speed in the net code i canceld the rewrite to sdl_net.
Ghoulsblade 18:15, 16 March 2006 (CET):you can check, if there is anything to be read with socket-sets : http://jcatki.no-ip.org/SDL_net/SDL_net.html#SEC40
why would you want to retrieve only part of the buffer ? it must be copyed to a local fifo anyhow, as messages don't have a fixed size, and you cannot determine if a message is complete until you look at the first bytes..
