Portable Compare And Swap (atomic operations) C/C++ library?
c, c++, lock-free, multithreading, portability
Solution
Intel Threading Building Blocks has a nice portable `atomic<T>` template which does what you want. But whether it is a small library or not can of course be debated..
Problem
Is there any small library, that wrapps various processors' CAS-like operations into macros or functions, that are portable across multiple compilers? PS. The atomic.hpp library is inside boost::interprocess::detail namespace. The author refuses to make it a public, well maintained library. Lets reopen the question, and see if there are any other options?
