But idea remains the same. On Tue, Apr 7, 2009 at 4:13 PM, Ovanes Markarian <om_boost@keywallet.com<mailto:om_boost@keywallet.com>> wrote: Just a question on your discussion. Why not to let mpl::if choose an appropriate overload, like: //... somewher in c private: inline void functionality_impl()const/or non const { //make impl here } inline void f() { f<typename mpl::if_c<SYNCH, ScopedCriticalSection, void*>::type>(); } template<class T> void f(); void f<ScopedCriticalSection>() { scs(cs); functionality_impl(); } void f<void*>() { functionlity_impl(); } Greetings, Ovanes
