libeio

Full-featured asynchronous I/O library for C

Libeio is a full-featured asynchronous I/O library for C, modelled in 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), 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).
