Hi,
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
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 :)
thanks and regards,
Thomas
