#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 from DMPlexGetSupportSize()

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.
