What is the pthreads library and how does it support real-time threads?

The pthreads library, or POSIX threads, is a standard for multi-threading in C/C++. It allows for the creation and management of threads, enabling concurrent execution of code.

Can you explain how it handles real-time threads specifically?

Certainly! The pthreads library provides mechanisms to prioritize threads, allowing real-time threads to be scheduled with higher priority than normal threads, ensuring timely execution.

What are some common use cases for real-time threads?

Common use cases include real-time data processing, multimedia applications, and systems requiring immediate response, like embedded systems.

Are there any limitations to using pthreads for real-time applications?

Yes, while pthreads can support real-time applications, limitations include potential priority inversion and the need for careful resource management to avoid latency.
