## Synopsis
```
#include "petscsys.h"   
PetscErrorCode PetscOptionsGetIntArray(PetscOptions options, const char pre[], const char name[], PetscInt ivalue[], PetscInt *nmax, PetscBool *set)
```
Not Collective


## Input Parameters

- ***options -*** options database, use `NULL` for default global database
- ***pre -*** string to prepend to each name or `NULL`
- ***name -*** the option one is seeking



## Output Parameters

- ***ivalue -*** the integer values to return
- ***nmax -*** On input maximum number of values to retrieve, on output the actual number of values retrieved
- ***set -*** `PETSC_TRUE` if found, else `PETSC_FALSE`





## Notes
The array can be passed as

- ***a comma separated list -*** 0,1,2,3,4,5,6,7
- ***a range (start-end+1) -*** 0-8
- ***a range with given increment (start-end+1:inc) -*** 0-7:2
- ***a combination of values and ranges separated by commas -*** 0,1-8,8-15:2


There must be no intervening spaces between the values.
