PetscViewerAndFormatCreate#

Creates a PetscViewerAndFormat struct.

Synopsis#

#include "petscviewer.h" 
PetscErrorCode PetscViewerAndFormatCreate(PetscViewer viewer, PetscViewerFormat format, PetscViewerAndFormat **vf)

Collective

Input Parameters#

  • viewer - the viewer

  • format - the format

Output Parameter#

  • vf - viewer and format object

Notes#

This increases the reference count of the viewer.

Use PetscViewerAndFormatDestroy() to free the struct

This is used as the context variable for many of the TS, SNES, and KSP monitor functions

This construct exists because it allows one to keep track of the use of a PetscViewerFormat without requiring the format in the viewer to be permanently changed.
