About:
Npth is a library implementing the GNU Pth API for portable preemptive threading. It uses POSIX threads or Windows fibers to provide an asynchronous threading model without requiring special kernel support. This allows multi-threaded applications to run portably across different operating systems.
Key Features:
  • Portable threading API compatible with GNU Pth
  • Preemptive scheduling of user-space threads
  • No kernel thread overhead for context switching
  • Compatible with POSIX threads and Windows
Use Cases:
  • Building multi-threaded applications that need portable thread behavior
  • Implementing asynchronous I/O operations in GNU software
  • Providing threading support in GnuPG and related cryptographic tools
Alternatives:
  • pthreads – Native POSIX threads requiring kernel support, heavier than Npth's user-space approach
  • boost::thread – C++ threading library requiring C++ runtime, not a direct C replacement
