#include "petscsys.h" PetscErrorCode PetscObjectIncrementTabLevel(PetscObject obj,PetscObject oldobj,PetscInt tab)Not Collective
|obj||- any PETSc object where we are changing the tab|
|oldobj||- the object providing the tab|
|tab||- the increment that is added to the old objects tab|
Notes: this is used to manage the output from options that are imbedded in other objects. For example the KSP object inside a SNES object. By indenting each lower level further the heirarchy of objects is very clear.
