SDL net

From GPWiki

The Game Programming Wiki has moved!

The wiki is now hosted by GameDev.NET at wiki.gamedev.net. All gpwiki.org content has been moved to the new server.

However, the GPWiki forums are still active! Come say hello.

SDL_net, a part of SDL, is a small sample cross-platform networking library, with a sample chat client and server application. It is available under the GNU Library General Public License. SDL_net gives a simple and portable interface for TCP and UDP protocols. For UDP sockets, SDL_net give an half-way connection: you can bind a socket to an address, avoiding the need of filling outgoing packets with the destination address. This is done using a channel number for the connection. Of course the classic connectionless method is also provided.
