[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.

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..
if the network recieved 32 bytes and i called a recv with a 64 buffer the function will block until another 32 bytes arive. - hagish 10:21, 18 March 2006 (CET)
