Thanks Victor for your previous answer!

I have the following problem:

I would like to implement an interface class that defines a pure virtual
method that could take any parameter as input, void inlcuded.
The first idea was to use a template, but in that case void is not admited
as a type right?

i.e.
template<typename T>
class A {

virtual do_something(T) = 0;

};

Then, one of the derive classes can't just do :

do_something(){...}

Because the compiler will complain for void not being a type...

Any work-around this?

Cheers

Manuel
