What are the differences between pthreads and std::thread?

What are the differences between pthreads and std::thread?

Pthreads is a C library for multi-threading, while std::thread is part of C++11's standard library. Pthreads is more low-level and offers more control, but std::thread is easier to use and integrates better with C++ features.

Which one should I use for a new C++ project?

If you're working in C++, it's generally recommended to use std::thread for its simplicity and better integration with C++ features. Pthreads can be used if you need specific low-level control.

Are there performance differences between them?

Performance can vary based on the application and how threading is implemented. In many cases, std::thread performs comparably to pthreads, but specific scenarios may favor one over the other.

Can I mix both in the same project?

Yes, you can mix pthreads and std::thread in the same project, but be cautious about managing resources and synchronization between them.

What about portability issues?

std::thread is more portable across different platforms since it's part of the C++ standard. Pthreads may require additional considerations for compatibility on non-POSIX systems.
