Mutexes in linux for processes

How can I create a mutex in linux that will work with different processes and will have string name?

I want something similar to CreateMutex in Windows OS.

There's a really nice freeware book Advanced Linux Programming with chapter on Interprocess communication especially 5.2 Processes Semaphores:

Linux provides a distinct alternate implementation of semaphores that can be used for synchronizing processes (called process semaphores or sometimes System V semaphores). Process sem- aphores are allocated, used, and deallocated like shared memory segments.

There's really thorough explanation and many examples so I recommend taking a look.

Use a semaphore - see http://man7.org/linux/man-pages/man7/sem_overview.7.html.

This will give you the same as a mutex and you can name them
