Gets information about a given distributed array.

### Synopsis

    #include "petscda.h"
    PetscErrorCode PETSCDM_DLLEXPORT DAGetInfo(DA da,PetscInt *dim,PetscInt *M,PetscInt *N,PetscInt *P,PetscInt *m,PetscInt *n,PetscInt *p,PetscInt *dof,PetscInt *s,DAPeriodicType *wrap,DAStencilType *st)

Not Collective

### Input Parameter

da -the distributed array

### Output Parameters

| dim | - dimension of the distributed array (1, 2, or 3)
| M, N, P | - global dimension in each direction of the array
| m, n, p | - corresponding number of procs in each dimension
| dof | - number of degrees of freedom per node
| s | - stencil width
| wrap | - type of periodicity, one of DA_NONPERIODIC, DA_XPERIODIC, DA_YPERIODIC, DA_XYPERIODIC, DA_XYZPERIODIC, DA_XZPERIODIC, DA_YZPERIODIC,DA_ZPERIODIC
| st | - stencil type, either DA_STENCIL_STAR or DA_STENCIL_BOX

### Note

Use PETSC_NULL (PETSC_NULL_INTEGER in Fortran) in place of any output parameter that is not of interest.

### Keywords
