Info about Object Id, give ONLY the Object ID

I have this adapted code:

//

···

-----------------------------------------------------------------------------
//
// -----------------------------------------------------------------------------
herr_t H5Utilities::closeFile(hid_t &fileId)
{
   herr_t err = 1;
   if (fileId < 0) { // fileId isn't open
     return 1;
   }

   // Get the number of open identifiers of all types
   // except files
   int32_t num_open = H5Fget_obj_count(fileId, H5F_OBJ_DATASET | H5F_OBJ_GROUP |
             H5F_OBJ_DATATYPE | H5F_OBJ_ATTR);
   if (num_open > 0) {
     std::cout << "WARNING: Some IDs weren't closed. Closing them." << std::endl;
     std::vector<hid_t> attr_ids(num_open, 0);
     H5Fget_obj_ids(fileId, H5F_OBJ_DATASET | H5F_OBJ_GROUP |
        H5F_OBJ_DATATYPE | H5F_OBJ_ATTR,
        num_open, &(attr_ids.front()) );
     for (int i=0; i<num_open; i++)
     {
       H5Utilities::closeHDF5Object(attr_ids[i]);
     }
   }

   err = H5Fclose(fileId);
   if (err < 0) {
     std::cout << logTime() << "Error Closing HDF5 File." << err << std::endl;
   }
   fileId= -1;
   return err;
}

Which I run to close a file to make sure everything is cleaned up. I have some other code that I am developing that is reporting that I still have ids that are open. Problem is I can not seem to track down what is being left open. Is there an API that I can use (Version 1.6.9/10) that given the Object ID, I can tell what path in the HDF5 file that object represents? I can obviously break up the initial getting of the objects to narrow it down to either a group or data set or attribute or what ever. But once I have the object ID, what can I do with it?

Thanks

  You should be able to use H5Iget_name() to do what you what.
