What is pthreads?

POSIX Threads, often referred to as pthreads, is a POSIX standard defining an API for creating and manipulating threads. It is a widely used model for concurrent programming, allowing multiple threads to run within a single process, sharing resources like memory space. Pthreads are commonly used to improve application performance by enabling parallel execution of tasks, especially in multi-core processor systems. It's utilized in a variety of applications, including server applications, simulations, and multimedia processing, to enhance responsiveness and throughput.
