inter-process semaphores in Windows

is there 开发者_开发技巧any kind of semaphore for processes in Windows API? I found this one

but it is only for thread as I understood, thanks in advance for any help

Look at the the help for CreateSemaphore() function: http://msdn.microsoft.com/en-us/library/ms682438(v=VS.85).aspx in the Remarks section, starting from "Multiple processes can handles....".

You'll find 3 cases there - all of them useful.

Use CreateSemaphore or CreateSemaphoreEx to create a named semaphore. You can use the name to access the semaphore from other locations by calling CreateSemaphore a second time.
