Reading&Writing NCSA HDF with LV

Has anyone written NCSA HDF file vi's? I have written a CIN to write
HDF files (2 2D arrays + dimension arrays, dimension names and file
descriptors). My read vi's work in isolation but often bomb in
combination when incorporated in larger programs. Are any vi's
available or CIN c-code?

The HDF libraries are canned entities from NCSA. I pass LV handles to
the HDF read, write utilities. I don't know if the HDF reads involve
malloc or calloc which may cause trouble with LV.

Try posting this to the info-labview mailing list
. Someone had something written up a few
years ago (I have a copy somewhere, but not handy). Actually might have
been Gary
Johnson of LabVIEW book fame.
