macOS Mutex equivalent in Cocoa

[satyam90]

I am using mutex objects in C# to create single instance of the application. I will try to create a mutex object in main, if already created, it will return displaying message "Another instance is running".
I would like to know the euqivalent of mutex in Cocoa. I couldn't find the equivalent of mutex in documentation. Or any other way is there to create single instance of application in Mac programming.

The very first result on Google for "Cocoa Mutex" returns the Apple documentation on the very subject.

Seriously: next time actually try searching instead of lying to us and saying you have.
