Libeio is a full-featured asynchronous I/O library for C, modelled in a similar style and spirit as libev. Features include: asynchronous read, write, open, close, stat, unlink, fdatasync, mknod, readdir, etc. (basically the full POSIX API). sendfile (native on Solaris, Linux, HP-UX, FreeBSD, emulated everywhere else), and read-ahead (emulated where not available). It is fully event-library agnostic and can easily be integrated into any event library (or used standalone, even in polling mode). It is very portable and relies only on POSIX threads. Its code, documentation, integration, and portability quality is currently below that of libev, but should soon be ready for use in production environments.
