Synopsis

#include "petscsys.h"   
PetscErrorCode PetscOptionsCreate(PetscOptions *options)

Logically Collective

Output Parameter

• options - Options database object

Note

Though PETSc has a concept of multiple options database the current code uses a single default PetscOptions object

Developer Notes

We may want eventually to pass a MPI_Comm to determine the ownership of the object

This object never got developed after being introduced, it is not clear that supporting multiple PetscOptions objects is useful
