[hdf-forum] Correct practice with C++ API

[Benjamin Scherrey]

    I've made a little progress since before. Have a few specific
questions and would appreciate any pointers or best practices on how
to accomplish these things with the C++ api:

1. I still can't seem to read bool values back for some reason. What
is the correct NATIVE_XXX type to use or should I be mapping to
something other than C++ boolean?
2. How does one control the quantity of results coming back from
DataSet::read()? All the behaviour I see points to it returning the
entire dataset. Some of my records have a million+ instances so that's
a lot of stuff to be manipulating in memory at once. How do I start at
a certain offset and read in a select quantity of items via the
DataSet (or some other) class?
3. I'm not yet writing to HDF5 via C++ but, once I do, I imagine I
will have the same question regarding DataSet::write().

    I'm attaching an updated version of yesterdays code so you can see
what I'm trying to do. Appreciate any advice on my approach here.

 thanx,
