About shiyanhui/libcsp
libcsp is a high-performance concurrency C library influenced by the CSP (Communicating Sequential Processes) model. It aims to provide a lightweight concurrency mechanism similar to goroutines in Go but implemented in C, with claims of 10x performance improvement over Golang. Key features include support for multiple CPU cores, a high-performance scheduler, lock-free channels, static stack size analysis at compile time, and integrated netpoll and timer support. The library is open-source under the MIT license and targets developers building concurrent systems in C.

FAQ
What is libcsp?
libcsp is a high-performance concurrency C library inspired by the CSP (Communicating Sequential Processes) model, similar to Go's goroutines but implemented in C. It is open-source under the MIT license.
Is libcsp free to use?
Yes, libcsp is open-source and licensed under the MIT license, allowing free use, modification, and distribution.
How does libcsp compare to Golang's goroutines?
The library claims to be 10x faster than Golang's goroutines for concurrency tasks, though actual performance may vary depending on the workload. It offers features like lock-free channels and compile-time stack analysis.
