    PetscErrorCode  PetscObjectGetTabLevel(PetscObject obj,PetscInt *tab)

Not Collective

### Input Parameter

| obj | - any PETSc object, for example a Vec, Mat or KSP. Thus must be cast with a (PetscObject), for example, PetscObjectGetComm((PetscObject)mat,&comm);

### Output Parameter

| tab | - the number of tabs

### 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 hierarchy of objects is very clear.
