 KL>> 2) Why ptr_multimap_adapter::transfer( iterator object,

 TO> Why do you think it should return an iterator?

ptr_multimap<std::string, int> a1;
ptr_multimap<std::string, int> a2;
typedef ptr_multimap<std::string, int>::iterator iterator;

a1.insert("a", 1);
a1.insert("a", 2);
a2.insert("a", 1);
a2.insert("a", 2);

iterator i = a1.insert("a", 3);
iterator r = a2.transfer(i, a1);      /// Will not work
return r;

    How can I do this with current interface in a simple way?

With best regards, Konstantin Litvinenko
