DAGetGlobalIndices
Returns the global node number of all local nodes, including ghost nodes.
Synopsis
int DAGetGlobalIndices(DA da, int *n,int **idx)
Not
Collective
Input Parameter
da -the distributed array
Output Parameters
n | - the number of local elements, including ghost nodes (or PETSC_NULL)
|
idx | - the global indices
|
Note
For DA_STENCIL_STAR stencils the inactive corner ghost nodes are also
includedin the list of local indices (even though those nodes are not
updatedduring calls to DAXXXToXXX().
Fortran Note
The Fortran interface is slightly different from that given below.
See the Fortran chapter of the users manual for details.
