Try the following: 1) Call H5Tcommitted() to check is the dataype is a named datatype 2) Call H5Iget_name() to get a full path to the named dataype.

Hi, Consider I have a dataset that uses a committed (named) datatype, what is the most efficient way to find the path of this datatype in an HDF5 file? Looking at the the API calls in H5T, the only way I can see is to scan all groups for committed datasets and calling H5Tequal() on each of them to find out whether this one equals the datatype of the dataset. The scanning might be very inefficient if the HDF5 file contains many groups with many members. Is there a more efficient way of doing that? How does h5dump get the information that it prints in the "DATATYPE" line for a dataset? Bernd _______________________________________________ Hdf-forum is for HDF software users discussion.
