What is the POSIX equivalent of Win32 Mutex?

Question

POSIX is mutexequivalent to Win32 CRITICAL_SECTION- its scope is limited to one process. Win32 mutex (Actually called the "mutant" on NT ground) serves as a mechanism for blocking the cross process. What is the pthreads equivalent for cross processes?

Answer 1

This is pthread_mutex_t with the pshared attribute set to PTHREAD_PROCESS_SHARED. However, you are responsible for placing such a mutex in shared memory that all processes can access - so it is not as simple as win32 api.
