[petsc-dev] DMDABoundaryType

[Lisandro Dalcin]

While updating petsc4py for the latest DMDA chages, and alto taking
into account some new in NumPy C API related to neighborhood
iterators,  I've got new idea. What about the API below?:

enum DMDABoundaryType:
    DMDA_BOUNDARY_NONE = 0
    DMDA_BOUNDARY_GHOSTED = 1
    DMDA_BOUNDARY_MIRROR = 2
    DMDA_BOUNDARY_PERIODIC = 4

PetscErrorCode DMDASetBoundaryType(DM dm, DMDABoundaryType bx,
DMDABoundaryType by, DMDABoundaryType bz)

Changes for GHOSTED and PERIODIC should be easy
(http://lkml.org/lkml/2000/8/25/132) ;-).

The new MIRROR boundary type could be implemented later.
