I have the following code:
void HandlePair( std::pair<int, char*>& mypair ) { }
void main() { boost::ptr_map<int, char> mymap; HandlePair( *mymap.begin() ); }
What's the proper way to accept pairs in the HandlePair function?
I'd suggest basing it on your actual ptr_map type, e.g.: void HandlePair(const boost::ptr_map<int, char>::value_type& mypair) {} I usually use map_type::value_type (using an appropriate typedef for map_type) even when working with std::map, since the type of a pair stored in a std::map<A, B> is NOT the same as std::pair<A, B>: it's actually std::pair<const A, B>. I have no idea what the transformation is for boost::ptr_map, but in any case, its value_type should give you what you want.
