PETSc version 3.15.5
DMPlexGetDepthStratum
Get the bounds [start, end) for all points at a certain depth. 
Synopsis
#include "petscdmplex.h"   
PetscErrorCode DMPlexGetDepthStratum(DM dm, PetscInt stratumValue, PetscInt *start, PetscInt *end)
Not Collective
Input Parameters
|  | dm | - The DMPlex object | 
|  | stratumValue | - The requested depth | 
Output Parameters
|  | start | - The first point at this depth | 
|  | end | - One beyond the last point at this depth | 
Notes
Depth indexing is related to topological dimension.  Depth stratum 0 contains the lowest topological dimension points,
often "vertices".  If the mesh is "interpolated" (see DMPlexInterpolate()), then depth stratum 1 contains the next
higher dimension, e.g., "edges".
