Coroutine

Coroutine is a small asymmetric coroutine library written in C. It is inspired by Lua-style coroutine behavior and uses a schedule-based model. Developers first open a schedule, create coroutines inside it, and then resume them from the same thread that opened the schedule. Coroutines in the same schedule share the stack, which makes it possible to create many coroutines without heavy memory overhead. The project is useful for C developers who want cooperative multitasking without depending on a larger runtime. Its design is minimal, low-level, and focused on giving programmers explicit control over coroutine creation, suspension, and resumption.
