Return the points on the out-edges for this point in the DAG
Synopsis#
#include "petscdmplex.h"
PetscErrorCode DMPlexGetSupport(DM dm, PetscInt p, const PetscInt *support[])
Not Collective
Input Parameters#
dm - The
DMPLEX
p - The point, which must lie in the chart set with
DMPlexSetChart()
Output Parameter#
support - An array of points which are on the out-edges for point
p
, its length is that obtained fromDMPlexGetSupportSize()
Fortran Notes#
support
must be declared with
PetscInt, pointer :: support(:)
You must also call DMPlexRestoreSupport()
after you finish using the returned array.
DMPlexRestoreSupport()
is not needed/available in C.
