Re: [boost] How to detect if f() returns void or not?

I would like to detect if the return type of a function is void or not within C++03 standard? I need that to implement new type traits to detect if types can be compared and to detect for example operator< returning void. The following code compiles only with c++0x standard and keyword decltype but not with c++03 standard and BOOST_TYPEOF. Frédéric

What about using function_traits::return_type ? -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35
