DMPlexGetPointGlobalField

get location of point field data in global Vec

#include "petscdmplex.h"   
PetscErrorCode DMPlexGetPointGlobalField(DM dm, PetscInt point, PetscInt field, PetscInt *start, PetscInt *end)

Not Collective

	dm	- DM defining the topological space
	point	- topological point
	field	- the field number

	start	- start of point data; returns -(globalStart+1) if point is not owned
	end	- end of point data; returns -(globalEnd+1) if point is not owned

Note: This is a half open interval [start, end)
