PetscObjectName

Gives obj a name if it does not have one

Synopsis

#include "petscsys.h"   
PetscErrorCode PetscObjectName(PetscObject obj)

Collective

Input Parameter

• obj - the PETSc object. It must be cast with a (PetscObject), for example, PetscObjectName((PetscObject)mat,name);

Notes

This is used in a small number of places when an object NEEDS a name, for example when it is saved to MATLAB with that variable name.

Use PetscObjectSetName() to set the name of an object to what you want. The SAWs viewer requires that no two published objects share the same name.

Developer Note

This needs to generate the exact same string on all MPI processes that share obj. The current algorithm may not always work.
