You need a set_ogg_malloc_handler(). That's it as far as the API goes.

As for the implementation, I'd suggest making a two-three line function 
named ogg_malloc() that does the right thing. Do a grep through the ogg and 
vorbis source to change all instances of "malloc" to
"ogg_malloc".

Hardly non-trivial.

Assuming you consider it acceptable to store that information in global
variables. Something that is done in _no_ other part of libvorbis. If
you're going to do this, why not just compile in a different malloc
function? It's more or less equivalent. There's no good reason to add
this,
that I can see.
