Thanks, Mark. I thought the field name (const char *) is packaged differently than the data tree. I am bumping my head to find an alternative character to represent division intuitively. Any suggestions?

Yes, I am pretty sure the slash character is used by HDF5 library to
break up dataset names into group paths much like a unix filesystem
does.

I don't know if there is a way to tell HDF5 to use a different separator
character for this purpose for a given file.

Hi All,
I am trying
               hid_t dataset_id = H5Dcreate(group_frame_id, "mass
(GeV/(c^2))", std_type_id, space_id, H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT);
And the returned dataset_id = -1. If I changed the string to "mass
(GeV_(c^2))", I got a valid dataset_id.
Is "/" a special/reserved character in HDF5? Is there such a reserved
character list for HDF5?
Thanks so much.

Best,
