RE: [Boost-Users] boost::function map with different return types

Julia, The only way I can think of accomplishing this is to have all the methods have the same return type. function<void> and function<int> are two distinct types. Assigning them both to a function<void> just doesn't seem right.

I tried something like that: "unsigned int i = functions["Function5"]();" but sadly it doesnt work, maybe cause in the map I declared for the return value "void"? How can I have such a map where to have functions with different return types in it and to get the return value after a call of the function through the map?
