Pthreads Library vs. std::thread: Which is More Portable?

What are the main differences between pthreads and std::thread in terms of portability?

Pthreads is a POSIX standard for threading, primarily used in Unix-like systems, while std::thread is part of the C++11 standard and is designed to be cross-platform. This means std::thread is generally more portable across different operating systems.

Are there any specific scenarios where one is preferred over the other?

Yes, if you're developing for a specific Unix-like environment, pthreads might offer better performance and control. However, for cross-platform applications, std::thread is usually the better choice due to its compatibility with various compilers and operating systems.

What about performance differences between the two?

Performance can vary based on the implementation and the specific use case. Pthreads may have lower overhead in some scenarios, but std::thread benefits from C++ optimizations and better integration with C++ features.

Can I use both in the same project?

Yes, you can use both in the same project, but it may complicate your code. It's generally advisable to stick to one threading model for consistency.
