WebOverview. pthreads or POSIX threads are an implementation of the thread API for C/C++. It allows the spawning of new concurrent process flows and the multithreading system, which allows parallel and distributed processing. It does so by dividing the program into subtasks whose execution can be interleaved to run in parallel. WebNote that we have a new Standard C++ Library header #include in which the functions and classes for threads are declared. Below is the diagram how the flow looks like. However, in the real world, things are not that ideal and more likely to be asymmetric. Probably, it may look more like the next picture.
