Re: [Boost-users] Question on std::binary_function template arguments

For now, my question concerns the first template argument to std::binary_function. Looking at the declarations for the standard mem_fun1_t and mem_fun1_ref_t, I don't know if this should be: 1) the full type passed as the first argument to the resulting functor, 2) such, but without the final &, 3) just the object's type, 4..n) something else?

Can someone clarify that for me?

I know this isn't the answer you're looking for, but IMO you should just avoid std::binary_function and friends. They don't buy you anything you can't get from embedding the typedefs directly, and they can inhibit the empty base optimization. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
