Why not use iterators in the style of the stream iterators? I once
implemented such a stackframe_iterator, modeled as a forward iterator.
Dereferencing the iterator yields a stackframe object. Its use was
extremenly simple:

stackframe_iterator start_frame( 0 ); // 0 means start from this frame
                                       // 1 is the frame of the caller,
stackframe_iterator end_frame;

// now use them however you like

I used dbghelp dll on windows, so the interface may not be portable to
every platform. Anyway, this is just a sugestion.
