Thread Safety in C

Question

imagine I write a library in C. Further, imagine this library to be used from a multi-threaded environment. How do I make it thread-safe? More specific: How do

Answer 1

If your goal is to be compatible on unix-like operating systems, I would use POSIX threading.

That being said, if you want to support windows as well, you'll need to have two code paths for this - pthreads on unix and Windows threads on Windows. It's fairly easy to just make your own "thread library" to wrap these.

There are quite a few that do this (like OpenThreads), but most of them I've used are C++, not C.
