About ptr sharing

I'm not sure if this needs to be said strictly, but I would like to consider common ptr as a garbage collection strategy.

I have two questions:

  • When sharing ptr to collect garbage; and when are other strategies like mark-sweep?
  • Is there a lib implemented by shared ptr in C?

Thank.
