Is there a difference between Boost's scoped mutex and WinAPi's critical section?

Question

In Windows environment, is Boost\'s scoped mutex using WinAPI\'s critical sections, or something else?

Answer 1

Win32's CRITICAL_SECTION can only be used among the threads of a single process. If you need to use something between processes, you need a mutex. Boost says nothing about critical sections so I would assume it is using mutexes.

"scoped" just means it has a wrapper that uses RAII to automatically unlock the mutex at the end of a particular scope.
