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

Using Posix threads sounds like a good idea to me (but I'm no expert). In particular, Posix has good primitives for ensuring mutual exclusion.

If you had to create a library without any dependencies, you would have to implement the mutual exclusion algorithms yourself, which is a bad idea.
