PetscViewerHDF5HasObjectAttribute

 Check whether an attribute is attached to the dataset matching the given PetscObject by name

Synopsis

#include "petscviewerhdf5.h"   
PetscErrorCode PetscViewerHDF5HasObjectAttribute(PetscViewer viewer, PetscObject obj, const char name[], PetscBool *has)

Input Parameters

viewer - The HDF5 viewer
obj - The object whose name is used to lookup the parent dataset, relative to the current group.
name - The attribute name

This fails if current_group/object_name doesn't resolve to a dataset (the path doesn't exist or is not a dataset). You might want to check first if it does using PetscViewerHDF5HasObject().
