BitFiend is a BitTorrent client written in C. It is multithreaded with POSIX threads. It can be built for Linux and has a command line interface.
The client has successfully torrented Ubuntu ISOs, academic torrents, and various multimedia files from popular torrent websites. It should work with most torrents!
At the moment, the client still lacks a number of features such as accurate bandwidth reporting. I plan to continue to extend its' functionality in the future.
To build the command-line client, run make bfcli
in the top-level directory.
To build the core of BitFiend as a static library, run make libbf
in the top-level
directory. The library API can be found in libbf/bitfiend.h
BitFiend does not depend on any third party libraries. It requires a C99 compiler with GNU extensions as well as POSIX compliance. Some non-portable Linux-specific code is present.
