DMPlexGetSupport

Return the points on the out-edges for this point in the DAG

#include "petscdmplex.h"   
PetscErrorCode DMPlexGetSupport(DM dm, PetscInt p, const PetscInt *support[])

Not collective

	mesh	- The DMPlex
	p	- The point, which must lie in the chart set with DMPlexSetChart()

support -An array of points which are on the out-edges for point p

Since it returns an array, this routine is only available in Fortran 90, and you must include petsc.h90 in your code.

You must also call DMPlexRestoreSupport() after you finish using the returned array.
