libcsp is a high-performance concurrency library for C implementing the Communicating Sequential Processes (CSP) model, inspired by Go's goroutines and channels. It provides a multi-core scheduler, lock-free channels, compile-time stack analysis, and netpoll/timer support.

Use cases

  • write concurrent C programs with goroutine-like coroutines
  • communicate between tasks using channels in C
  • build high-throughput network servers in C
  • replace threads with lightweight coroutines for better performance
  • implement CSP-style message passing in C applications

When to choose

  • you need Go-style concurrency in a C codebase
  • raw scheduling and channel performance is critical
  • you want lightweight coroutines across multiple CPU cores

When to avoid

  • your project is in Go, Rust, or another language with native async/concurrency
  • you need a battle-tested, widely-adopted concurrency runtime
  • you require extensive documentation and community support
