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

Output Parameter#
