# DMGetFirstLabeledPoint
Find first labeled `point` in `odm` such that the corresponding point in `dm` has the specified `height`. Return `point` and the corresponding `ds`. 
## Synopsis
```
#include "petscdmplex.h"   
PetscErrorCode DMGetFirstLabeledPoint(DM dm, DM odm, DMLabel label, PetscInt numIds, const PetscInt ids[], PetscInt height, PetscInt *point, PetscDS *ds)
```

## Input Parameters

- ***dm -*** the `DM`
- ***odm -*** the enclosing `DM`
- ***label -*** label for `DM` domain, or `NULL` for whole domain
- ***numIds -*** the number of `ids`
- ***ids -*** An array of the label ids in sequence for the domain
- ***height -*** Height of target cells in `DMPLEX` topology
