Hi again, Daniel, A little correction to my previous message: "If you continue using your current approach, you will need fg_p to be of type Group so that the correct exception, GroupIException, would be thrown."
Should be: "If you continue using your current approach, you will need fg_p to be of type Group or H5File so that the correct exception, GroupIException or FileIException, would be thrown." I'm sure you could figure it out, but it makes me feel better saying it. :) Binh-Minh >-----Original Message----- >From: [email protected] [mailto:hdf-forum- >[email protected]] On Behalf Of Binh-Minh Ribler >Sent: Thursday, January 27, 2011 9:13 AM >To: 'HDF Users Discussion List' >Subject: Re: [Hdf-forum] C++ API: Which exception for openDataSet? > >Hi Daniel, > >As Quincey said, H5Lexist would be a better way, but the C++ API does not >have a wrapper for that yet.
