Removes all options form the database leaving it empty.

Synopsis#

#include "petscsys.h"   
PetscErrorCode PetscOptionsClear(PetscOptions options)

Logically Collective

Input Parameter#

options - options database, use NULL for the default global database

Note#

The collectivity of this routine is complex; only the MPI processes that call this routine will have the affect of these options. If some processes that create objects call this routine and others do not the code may fail in complicated ways because the same parallel solvers may incorrectly use different options on different ranks.
