About Pithikos/C-Thread-Pool

C-Thread-Pool is a minimal but advanced thread pool library implemented in ANSI C, fully compliant with POSIX threads. It provides a simple and easy-to-digest API for creating thread pools, adding work, waiting for completion, pausing/resuming execution, and querying the number of working threads. The library is well-tested, released under the MIT license, and designed for lightweight integration into any C project requiring efficient concurrent task management.

Pros & Cons

Pros
  • Very minimal and focused implementation
  • POSIX compliant, portable on Unix-like systems
  • Simple API with only a few functions
  • Includes pause/resume capabilities not commonly found in minimal pools
  • Well-tested and actively maintained
  • MIT license allows free use in commercial projects
Cons
  • Requires POSIX threads environment (not natively supported on Windows without compatibility layers)
  • Not precompiled; must be compiled with the project
  • Limited to C (no direct C++ wrappers provided)
  • No built-in load balancing or thread reuse policies beyond basic pool
