#include "petscis.h" PetscErrorCode ISClearInfoCache(IS is, PetscBool clear_permanent_local)Not collective
| is | - the index set | |
| clear_permanent_local | - whether to remove the permanent status of local properties |
NOTE: because all processes must agree on the global permanent status of a property, the permanent status can only be changed with ISSetInfo(), because this routine is not collective
