libuv: Asynchronous Event Library for Multi-Platform Development

libuv is a multi-platform C library providing asynchronous event capabilities and I/O abstraction, enabling efficient and scalable network applications and servers

What is Libuv?

libuv is an open-source, cross-platform C library that provides asynchronous I/O capabilities to applications. It was originally developed for use in Node.js to handle asynchronous events and I/O operations, but can be used as a standalone library in any C application.

Some key capabilities and features of libuv:

  • Asynchronous file system operations like reading, writing, and renaming files and directories.
  • Asynchronous networking using TCP and UDP sockets.
  • Asynchronous DNS resolution.
  • Cross-platform support for Windows, Linux, macOS, and Unix.
  • Event loop and worker thread pool to execute code asynchronously.
  • Synchronization primitives like mutexes and semaphores.
  • IPC mechanisms like pipes and streams.

libuv makes it easy to write scalable network services by providing a consistent API across platforms for commonly needed asynchronous operations. It handles complex concurrency, threading and synchronization issues behind a simple interface. Using libuv allows focusing on application logic rather than complex non-portable system I/O code.
