PetscDualSpaceViewFromOptions

View a PetscDualSpace based on values in the options database

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceViewFromOptions(PetscDualSpace A, PeOp PetscObject obj, const char name[])

Collective

Input Parameters

• A - the PetscDualSpace object

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

• name - command line option name

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.
