DAGetOwnershipRanges

Gets the ranges of indices in the x, y and z direction that are owned by each process

Synopsis

#include "petscda.h"   
PetscErrorCode PETSCDM_DLLEXPORT DAGetOwnershipRanges(DA da,const PetscInt *lx[],const PetscInt *ly[],const PetscInt *lz[])
Not Collective

Input Parameter

da -the DA object

Output Parameter

lx - ownership along x direction (optional)
ly - ownership along y direction (optional)
lz - ownership along z direction (optional)

Note: these correspond to the optional final arguments passed to DACreate(), DACreate2d(), DACreate3d()

In Fortran one must pass in arrays lx, ly, and lz that are long enough to hold the values; the sixth, seventh and eighth arguments from DAGetInfo()

In C you should not free these arrays, nor change the values in them. They will only have valid values while the DA they came from still exists (has not been destroyed).
