Hello, All!

I have a couple of questions about ptr_container library. Specificaly

1) Why ptr_multimap_adapter::insert has non const key_type argument?

This is due to exception-safety concerns. If the construction of the key can throw, the heap allocated object can throw.

2) Why ptr_multimap_adapter::transfer( iterator object, ptr_multimap_adapter& from ) has void return type instead of iterator?

Why do you think it should return an iterator? -Thorsten
