octave c++ documentation

[Jonathan Stickel]

I am trying to write some octave functions in c++.  I have read "Da Coda 
Al Fine" and looked at the "C++ API" as linked from the octave-forge 
webpage.  However, those references are insufficient to learn about all 
that is available in the octave c++ core.  Is there any other 
documentation that I am not aware of?  I would like to have a reference 
for things like OCTAVE_LOCAL_BUFFER, octave_read_double, etc, and some 
better documentation of the octave classes.

Thanks,
Jonathan
