Re: [Boost-users] [mpl] how to find out whether a function is implemented

I hope the MPL label is right. At least the question has *some* relevance to metaprogramming.

Basically, I need to find out whether a certain function F over a certain type is defined, and if yes, take its address.

I can help you with the first part: http://www.boost-consulting.com/boost/boost/detail/is_incrementable.hpp shows an example determining if ++x is defined. However, reliably taking the address of an overloaded function involves knowing the exact types in its signature. I'm not sure how you can do that. -- Dave Abrahams Boost Consulting www.boost-consulting.com
