#include "petscdmplex.h"   
PetscErrorCode DMPlexPointGlobalRef(DM dm, PetscInt point, PetscScalar *array, void *ptr)
Not Collective
Input Parameters#
- dm - - DMdefining topological space
- point - topological point 
- array - array to index into 
Output Parameter#
- ptr - address of reference to point data, type generic so user can place in structure; returns NULL if global point is not owned 
Note#
A common usage when data sizes are known statically:
  struct { PetscScalar foo,bar,baz; } *ptr;
  DMPlexPointGlobalRef(dm,point,array,&ptr);
  ptr->foo = 2; ptr->bar = 3; ptr->baz = 5;
