PetscSectionViewFromOptions

View the PetscSection based on values in the options database

Synopsis

#include "petscsection.h"   
PetscErrorCode PetscSectionViewFromOptions(PetscSection A, PetscObject obj, const char name[])

Collective

Input Parameters

• A - the PetscSection object to view

• obj - optional object that provides the options prefix used for the options, pass NULL to use the options prefix of A

• name - command line option

Options Database Key

• -name viewer_specification - See PetscOptionsCreateViewer() for the values of viewer_specification

Note

This checks the options database, creates the viewer on-the-fly, uses it and then destroys it. Hence it should not be called in heavily used routines, rather PetscOptionsCreateViewer() should be used to construct the viewer once which can then be utilized in the heavily used routine.
