I want one of my object, not to be paged out unless and until I am done with my object. The way mlock() behave.

Is there any way to do this in cocoa?

First answer: No. You can't lock all of the code and metadata associated with the object, so you could still get page faults when you try to call methods. Also, method dispatch sometimes takes locks, which is as bad as a page fault depending what you're trying to do.

Second answer: Use mlock().
