I am attempting to read an HDF5 file (attached) that was created by a
python app using pyTables. In this case I need to use C++ to do the
processing of the data. I think I have things setup correctly but I
seem to be getting garbage results out of most of my fields. Here is
the output of my initial read attempts:
--- snip ---
h5reader opening 'test.h5'.
File: test.h5
Size:63712
Object Count:1
Opening Group.
AUDiiO group has 5 in it.
Opening DataSet.

Done.

Clearly something is off. Also, it is not quite clear from the docs
how to control the quantify of objects being read from or written to
the database. In the real simulation file I approach one million
AUDiiOUser instances. It isn't clear to me how to avoid reading all of
them at once via the Group interface. Appreciate any assistance or
pointers you may have. My deadline's pretty short on this one and I
can't seem to get past the simple business of reading the existing
data.
thanx much,
