DMPlexGetCone

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

Synopsis

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

Not Collective

Input Parameters

• dm - The DMPLEX

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

Output Parameter

• cone - An array of points which are on the in-edges for point p, the length of cone is the result of DMPlexGetConeSize()

Fortran Notes

cone must be declared with

  PetscInt, pointer :: cone(:)

You must also call DMPlexRestoreCone() after you finish using the array. DMPlexRestoreCone() is not needed/available in C.
