OK, here's a modified version of yours that generates the same size
object file using GCC 4.1.0 (actually, the C++ version is 2 bytes
larger because of a bad register allocation choice, but who's
counting?).
Thanks for the improvements - I'll incorporate them back into my version.
I also made the C interface parameterizable for IndexType and
EntryType, added the missing functions to the C++ version (though I'm
not sure that they should be public at all), and added some comments.
I added CBUF_GetPopEntryPtr and CBUF_AdvancePopIdx for cases where
you're using a circular buffer of structures and don't want to make a
copy outside of the circular buffer.
CBUF_GetPopEntryPtr allows you to snag a pointer to the structure
inside the circular buffer, and once you've finished with it, you can
call CBUF_AdvancePopIdx to "consume" the item.
So, for the intended purposes, the GetEntryPtr and Advance functions
should be public.
