About:
GNU Pth is a library for portable multi-threading that provides a lightweight, non-preemptive scheduling mechanism. It enables event-driven multitasking on top of standard kernel threads without relying on OS-specific kernel support. This allows for efficient concurrency in applications where traditional threading models may be too heavy or unavailable.

Key Features:

Portable across numerous operating systems
Non-preemptive, priority-based scheduling
Minimal resource footprint compared to kernel threads
API compatible with POSIX threads (pthreads)

Use Cases:

Implementing concurrency in network servers and daemons
Porting threaded applications to systems with limited thread support
Building event-driven applications with cooperative multitasking

Alternatives:

pthreads – Standard OS-level threads; heavier but preemptive and native to Unix-like systems.
libcoro – Similar lightweight coroutines; Pth offers a broader API and scheduling model.
