# DMLabelGetValueIS
Get an `IS` of all values that the `DMlabel` takes 
## Synopsis
```
#include "petscdmlabel.h"   
#include "petscsection.h"   
PetscErrorCode DMLabelGetValueIS(DMLabel label, IS *values)
```
Not Collective


## Input Parameter

- ***label -*** the `DMLabel`



## Output Parameter

- ***is    -*** the value `IS`





## Notes
The output `IS` should be destroyed when no longer needed.
Strata which are allocated but empty [`DMLabelGetStratumSize()` yields 0] are counted.
If you need to count only nonempty strata, use `DMLabelGetNonEmptyStratumValuesIS()`.
