Libuv
Software library for asynchronous I/O
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, since version 1.45.0, Linux io_uring for select asynchronous file operations. It is primarily designed for use in Node.js but is also used by other software projects. It was originally an abstraction around libev or Windows IOCP, as libev does not support IOCP. In node-v0.9.0's version of libuv, the dependency on libev was removed.

02Origin of the name
According to libuv developer Ben Noordhuis, the name libuv originally had no specific meaning, but as people kept asking about it, they made something up. They came up with Unicorn Velociraptor, which became the logo of the library.
