#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
