PETSc version 3.15.5
ISRestoreIndices
Restores an index set to a usable state after a call to ISGetIndices(). 
Synopsis
#include "petscis.h" 
PetscErrorCode  ISRestoreIndices(IS is,const PetscInt *ptr[])
Not Collective
Input Parameters
|  | is | - the index set | 
|  | ptr | - the pointer obtained by ISGetIndices() | 
Fortran Note
This routine is used differently from Fortran
   IS          is
   integer     is_array(1)
   PetscOffset i_is
   int         ierr
      call ISGetIndices(is,is_array,i_is,ierr)
  Access first local entry in list
     value = is_array(i_is + 1)
     ...... other code
      call ISRestoreIndices(is,is_array,i_is,ierr)
See the Fortran chapter of the users manual and
petsc/src/vec/is/tests for details.
Note
This routine zeros out ptr. This is to prevent accidental us of the array after it has been restored.
