Notes: Call <A HREF="../Viewer/PetscViewerRestoreSingleton.html#PetscViewerRestoreSingleton">PetscViewerRestoreSingleton</A>() to return this <A HREF="../Viewer/PetscViewer.html#PetscViewer">PetscViewer</A>, NOT <A HREF="../Viewer/PetscViewerDestroy.html#PetscViewerDestroy">PetscViewerDestroy</A>()
<P>
This is most commonly used to view a sequential object that is part of a
parallel object. For example block Jacobi <A HREF="../PC/PC.html#PC">PC</A> view could use this to obtain a
<A HREF="../Viewer/PetscViewer.html#PetscViewer">PetscViewer</A> that is used with the sequential <A HREF="../KSP/KSP.html#KSP">KSP</A> on one block of the preconditioner.
