Subject: C extensions: disable GC for a Ruby object and enable GC later for it

Hi, I do know this is very commented subject but I don't understand it clearly:

I'm coding a Ruby C extension which usess Ruby objects (Proc objects,
class instances...) asynchronously, which means that I need to tell CG
not to try those objects until I use them so they can be GC'd.

Could I know which two C functions should I use?:

1) a function for avoiding GC on a given Ruby object (VALUE).
2) a function to re-enable GC on a given Ruby object (VALUE).

Thanks a lot.
