the most recent version of the API is in C, and is intended to remain
that way. I showed you the header in the mail message. It is missing
mostly just the definition of a port and nframes_t. I will add that,
and send it again. the client side API doesn't include any other
objects or functions than the ones I showed. there is the issue of
gain control which i have left out (temporarily).

Ardour has already been ported to something very close to this
model. I have not yet added metering, and input monitoring is deeply
problematic but everything else works.
This version is a branch from the mainline CVS version and I have not
checked it in at this time.
the main() function doesn't do anything interesting. I think you are
interested in the interaction of the client and the engine, but thats
not part of the API and is transparent to the client (which just
supplies callback functions). it happens via mechanisms that are not
specified. i happen to have an implementation of that, but you seem to
dislike getting into implementation detail so early ;)
