libmill
A C library that brings Go-style coroutines and channels to C programming for lightweight concurrency.
What is libmill?
Libmill is a C library that implements Go-style concurrency primitives, bringing coroutines and channels to the C programming language. It enables C developers to write concurrent programs using lightweight coroutines instead of traditional threads, simplifying concurrent programming while maintaining performance.
C developers and systems programmers who need lightweight concurrency solutions and want to use Go-style patterns in their C applications.
Developers choose Libmill because it provides a clean, familiar concurrency model from Go while keeping C's performance characteristics, eliminating the complexity of thread management and synchronization.
Overview
Go-style concurrency in C
Use Cases
Best For
- Implementing concurrent network servers in C
- Writing lightweight parallel processing applications
- Porting Go concurrency patterns to C codebases
- Building event-driven systems without thread overhead
- Educational projects teaching concurrency in C
- Systems programming requiring coroutine-based concurrency
Not Ideal For
- Applications requiring true multi-threaded parallelism for CPU-bound computations
- Projects with strict real-time constraints where coroutine scheduling introduces unpredictability
- Teams already heavily invested in POSIX threads or asynchronous I/O libraries like libuv
Pros & Cons
Pros
Implements coroutines and channels similar to Go, providing a familiar and effective model for concurrent programming in C, as highlighted in the key features.
Uses stackful coroutines for concurrent execution without threads, reducing memory and context-switching overhead for I/O-bound tasks, per the description.
Works across different platforms and operating systems, making it suitable for diverse deployment environments, as noted in the key features.
Licensed under MIT/X11, allowing unrestricted commercial and personal use without legal hurdles, as stated in the README.
Cons
Documentation is hosted separately at libmill.org, which may be less accessible or up-to-date compared to integrated documentation, requiring additional effort for developers.
As a C library focused on Go-style concurrency, it lacks the rich tooling and community support of languages like Go, potentially increasing development complexity.
Coroutines are lightweight but don't inherently leverage multi-core processors; for CPU-intensive tasks, traditional threading might be more effective, limiting its scope.
