Libevent is an event notification library that provides asynchronous I/O and event-driven programming capabilities for C applications.
The library solves the problem of managing multiple concurrent I/O operations and events across different platforms by abstracting away platform-specific details. It offers a unified API that works with various event notification mechanisms, allowing developers to write portable, high-performance networking and asynchronous code without worrying about whether the underlying system uses select, poll, epoll, kqueue, or other backend mechanisms.
Libevent suits projects that require cross-platform asynchronous networking, such as servers, clients, and event-driven applications. It is particularly valuable for developers building systems that need to handle many concurrent connections or events efficiently. The library is available through standard package managers including vcpkg, making integration straightforward. The project supports multiple build systems, with CMake being the current standard for both Unix and Windows platforms, while Autoconf is deprecated as of version 2.2.
Development activity shows consistent maintenance with established channels for community engagement. The project accepts contributions through pull requests on GitHub and maintains a mailing list for user discussion and development coordination. Bug reports, feature requests, and issues are tracked on GitHub, and the team also accepts traditional git patches submitted via the mailing list. Documentation is actively maintained, including a work-in-progress manual and building guides that cover platform-specific installation procedures.
