Simple question: How to verify two types are the same?
Hi all... I know this is a simple question, but I can't figure out which boost function to use. How do I find out if two types are the same type? For example: template<C1, C2> void compare() { if(boost::types_are_the_same<C1, C2>::result == true) ... } Thanks! --Steve Stephen Gross Case Western School of Medicine Cleveland, OH "The large print giveth and the small print taketh away." - Tom Waits

Almost. Use boost::is_same<C1,C2>::value See http://www.boost.org/libs/type_traits/index.html#relationships HTH // Fredrik Blomqvist
Try boost::is_same<C1, C2>::value

This works at compile time.

Try boost::is_same<C1, C2>::value
I tried this, but I think it works at runtime, not compile time (using typeid(...)). I need to find a compile-time solution...
