libuv is a multi-platform C library that provides support for asynchronous I/O based on event loops. It supports epoll(4), kqueue(2), Windows IOCP, Solaris event ports and Linux io_uring. It is primarily designed for use in Node.js but it is also used by other software projects.[3] It was originally an abstraction around libev or Microsoft IOCP, as libev doesn't support IOCP on Windows. In node-v0.9.0's version of libuv, the dependency on libev was removed.[4]
