PetscViewerHDF5ReadObjectAttribute

Read an attribute from the dataset matching the given PetscObject by name

Synopsis

#include "petscviewerhdf5.h" 
PetscErrorCode PetscViewerHDF5ReadObjectAttribute(PetscViewer viewer, PetscObject obj, const char name[], PetscDataType datatype, void *defaultValue, void *value)

Collective

Input Parameters

• viewer - The PETSCVIEWERHDF5 viewer

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

• name - The attribute name

• datatype - The attribute type

• defaultValue - The default attribute value

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().
