PetscObjectInheritPrintedOptions#

If the child object is not on the rank 0 process of the parent object and the child is sequential then the child gets it set.

Synopsis#

#include "petscsys.h"    
PetscErrorCode PetscObjectInheritPrintedOptions(PetscObject pobj, PetscObject obj)

Input Parameters#

  • pobj - the parent object

  • obj - the PetscObject

Developer Notes#

This is used, for example to prevent sequential objects that are created from a parallel object; such as the KSP created by PCBJACOBI from all printing the same help messages to the screen

This will not handle more complicated situations like with PCGASM where children may live on any subset of the parent’s processes and overlap
