Iterating part way through a std::map

[AnotherMuggle]

I have a std::map which I want to be able to iterate part way though, then go off and do "other things" and later resume iteration where I left off.

There is a chance that items may be added or removed from the std::map during doing the "other things".

Is there a correct way to go about this?

Any suggestions welcome

Thanks,

iterators remain valid after insertions/deletions ( excluding iterators pointing to deleted elements, of course ) so it's safe to "resume" iteration without causing undefined behavior. That said, it may still be unsafe from a logical point of view, because you're only guaranteed that elements are traversed in order and nothing more in this case ( you could end up missing some of them ). So, it depends on what your goal is at a higher level ...
