Re: [Boost-users] success of a multi-index container insertion

As I need to know if a insertion in my multi-index container succeded or not I've asked me and now you: How can I get a bool from inserting a new object?

My problem:

MyMultiIndex mmi; MyClass mc0; MyClass mc1 = mc0; mmi.insert(mc0); // mc0 inserted mmi.insert(mc1); // mc1 not inserted

http://www.boost.org/doc/libs/1_38_0/libs/multi_index/doc/reference/ord_indi... "std::pair insert(const value_type& x); Returns: The return value is a pair p. p.second is true if and only if insertion took place. On successful insertion, p.first points to the element inserted; otherwise, p.first points to an element that caused the insertion to be banned. Note that more than one element can be causing insertion not to be allowed."
