How do pthreads and std::thread compare in terms of compatibility?

Pthreads and std::thread serve similar purposes but differ in their implementation and compatibility across platforms. Pthreads is a C library for multi-threading, while std::thread is part of C++11 and later. Are you looking for specific compatibility issues?

Yes, are there any specific platforms where one is preferred over the other?

Yes, pthreads is often preferred in POSIX-compliant systems like Linux, while std::thread is more portable across different C++ compilers and platforms. It abstracts some of the complexities of pthreads.

What about performance differences between the two?

Performance can vary based on the implementation and use case. Generally, std::thread may introduce some overhead due to its abstraction, but in many scenarios, the difference is negligible. Profiling is recommended for critical applications.

Are there any specific features that one offers that the other doesn't?

Yes, std::thread offers features like RAII (Resource Acquisition Is Initialization) for automatic resource management, which pthreads lacks. Additionally, std::thread integrates better with C++ standard library features like futures and promises.
