Introduction

In this tutorial we learn how to install pthsem on Fedora 34.

What is `pthsem`

Pth is a very portable POSIX/ANSI-C based library for Unix platforms which provides non-preemptive priority-based scheduling for multiple threads of execution (“multithreading”) inside server applications. All threads run in the same address space of the server application, but each thread has it’s own individual program-counter, run-time stack, signal mask and errno variable. pthsem is an extend version, with support for semaphores added. It can be installed parallel to a normal pth. The header file is called pthsem.h, the configuration program pthsem-config and the autoconf macro AC_CHECK_PTHSEM. pthsem 2.0.7 22.fc34 x86_64 92 k pthsem-2.0.7-22.fc34.src.rpm fedora The GNU Portable Threads library extended with semaphore support http LGPLv2+ Pth is a very portable POSIX/ANSI-C based library for Unix platforms which provides non-preemptive priority-based scheduling for multiple threads of execution (“multithreading”) inside server applications.
