My code is likely wrong, but the 'pos' parameter is confusing
me. It is described as the "input byte position in stream" but
the example doesn't advance it inside the while loop, which
seems illogical. The implementation of parse2() seems to just
pass it around on behalf of the caller without using it, except
when initializing cur_offset. At this point, I don't know what
I should pass for the pos value, but perhaps it doesn't matter.

I haven't found a real world example of the api being used.
