How To Implement Mutex In Windows

Hi all,

In windows API we have 3 functions to control mutex:
CreateMutex,OpenMutex, and ReleaseMutex.

Currently, I want to implement it by myself so I have google it but I found nothing.

What should I do to solve this problem ?

Thanks.

Hey, thank for your quickreply. But you have missunderstood me.

I just want to implement 3 above functions like CreateMutex,OpenMutex, and ReleaseMutex by myself.

Can I ask why?

WElcome in the world of "reinvent the wheel"! :wave:

And I'm afraid, you won't get much help in that... :eek:

Actually, I doubt there is any sense in trying to implement Windows kernel object functionality in user mode. Or did you mean you are ready to break into the kernel? :)

Do you qualify this as problem? May I ask you why?

hi, thanks for your quick answer.

Cause it's a question from my friend. He had an interview from Aricent Company. And he asked me for the solution. But I know nothing.

The correct interview answer would be to describe how to use the CreateMutex et. al. family of api's. You could go on to say that implementing them would be pointless since the system provides them for you.

If i'm reading this correctly, you are asking how if you were to write a kernal you would provide mutexes. The commonly used algorithms are Dekkers and Petersons.
