Re: [Boost-users] [bind] Pointer to functions as template parameters

...

template <class T, T&> struct nontypeadapt;

template<class Ret, Ret (&func)()> struct nontypeadapt <Ret(), func> { typedef Ret result_type; Ret operator() () { return func(); } };

then

typeid(boost::bind(nontypeadapt<void(), func1>())) != typeid(boost::bind(nontypeadapt<void(), func2>()))

However, the signature has to be given at the call site, it's repetitive to define all specializations of nontypeadapt, and it brings more forwarding problems of it's own. Any ideas?

I think you can only pass functions with external linkage as parameters to templates, which I think it makes it unusable...

I believe that's true, yes, but it's usable nonetheless. The assembler generated by vc71 for a bind with nontypeadapt is better, too. Bruno
