# DMDAGetOwnershipRanges
Gets the ranges of indices in the x, y and z direction that are owned by each process 
## Synopsis
```
#include "petscdmda.h"   
PetscErrorCode DMDAGetOwnershipRanges(DM da, const PetscInt *lx[], const PetscInt *ly[], const PetscInt *lz[])
```
Not Collective


## Input Parameter

- ***da -*** the `DMDA` object



## Output Parameters

- ***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 `DMDACreate()`, `DMDACreate2d()`, `DMDACreate3d()`

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

These numbers are NOT multiplied by the number of dof per node.


## Fortran Note
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 `DMDAGetInfo()`
