asynchronous event notification library - runtime library
Libuv is the asynchronous library behind Node.js. Very similar to libevent or libev, it provides the main elements for event driven systems: watching and waiting for availability in a set of sockets, and some other events like timers or asynchronous messages. However, libuv also comes with some other extras like:
* files watchers and asynchronous operations * a portable TCP and UDP API, as well as asynchronous DNS resolution * processes and threads management, and a portable inter-process communications mechanism, with pipes and work queues * a plugins mechanism for loading libraries dynamically * interface with external libraries that also need to access the I/O.
This package includes the dynamic library against which you can link your program.
