[Boost-users] pointer to member function of multi_index

Hi, I am sure this is due to some trivial mistake; the statement to create a pointer member function insert of multi_index container fails in the following code: typedef multi_index_container< std::pair, indexed_by< ordered_unique, int, &pair::first> > > > mic; std::pair (mic_index::*fn)(pair) = &mic_index::insert; //compile error The error is due to mismatch in signature as given in the error: std::pair, ... std::pair, bool>... If need be I can post full error message. Appreciate any suggestions. Thanks sandeep
