anet: a networking library for peer-to-peer games September 4, 2001 Dan Kegel dank-anet@kegel.com http://www.kegel.com/anet This is the source code to the library used by some multiplayer games released by Activision and others between 1995 and 2000. It is copyright 1995-2001 by Activision, and is now released under the LGPL. It is hoped that this will enable people still playing those games to set up and run their own game servers if desired. Also, the library may still be of some interest to game programmers looking for a peer-to-peer game networking library to use or study. Finally, some of the techniques used in the library (e.g. the NAT compatibility scheme, the crash logger, the reliable transport built on top of UDP, the strlkup internationalization code, etc.) may also be of some interest to other programmers. Portions of the library (e.g. the score reporting system) were never really completed. Other portions (e.g. the automatic patch downloader) are not appropriate for use with untrusted servers, so are no longer fully documented or supported. The library currently builds on Linux and Windows 95 and higher. It has been compiled under MS-DOS and MacOS, but that has not been tested recently. A partial Java binding is also provided. The library is byte-order-safe, and interoperates properly between big- and little-endian machines. For a packing list and links to documentation, see index.html.
