Consider the following task: Given a -) pointer to a function, and -) an iterator range with elements of type void *, the function-ptr shall be called with all the elements in the range as arguments.
So conceptionally something like this:
template <typename Func, typename Iter> void make_call(Func, Iter begin, Iter end) { int n = std::distance(begin, end); (*Func) (*(begin), *(begin + 1), *(begin + 2), ..., *(begin + n - 1)) }
The interface (function declaration) here is +- what I want, the implementation shown of course is dummy-code not working. Does boost provide a more or less easy way to get this implementation smoothly done? C++ is 2003 version, so code must be compatible with e.g. VS 2008.. Note that I would know in principle a way how to do implement it myself, which involves the creation of a separate class for each number of arguments, but that's precisely what I want to avoid and I hope that wheel has already been invented in some boost-library :)
Is 'Func' a C-style vararg function, or is it a function object where the number of arguments it takes is known at compile time (perhaps being a choice among a finite number of overloads)? Regards, Nate
