🔗 Go-flavored concurrency in C

Go's concurrency model is attractive, but can it be mimicked in C using POSIX threads? This article delves into that question, exploring how to forge Go-like concurrency in C without runtime support and garbage collection. The writer introduces Solod, a strict Go subset that compiles to C, utilizing POSIX thread constructs such as mutexes and condition variables as its foundation.

The piece details various concurrency mechanisms like atomics, the worker pool, and task scheduling. Specific code snippets illustrate the direct translations from So to C, shedding light on performance trade-offs inherent to using OS threads versus lightweight goroutines. The core takeaway is clear: while achieving Go-like concurrency in C is challenging due to the shortcomings of POSIX threads, significant capabilities remain realizable by leveraging the right primitives and accepting the associated trade-offs.
