# PetscOptionsIntArray
Gets an array of integers for a particular option in the database. 
## Synopsis
```
#include "petscsys.h"
PetscErrorCode PetscOptionsIntArray(const char opt[],const char text[],const char man[],PetscInt value[],PetscInt *n,PetscBool  *set)
```
Logically Collective on the communicator passed in `PetscOptionsBegin()`


## Input Parameters

- ***opt -*** the option one is seeking
- ***text -*** short string describing option
- ***man -*** manual page for option
- ***n -*** maximum number of values



## Output Parameters

- ***value -*** location to copy values
- ***n -*** actual number of values found
- ***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.

Must be between a `PetscOptionsBegin()` and a `PetscOptionsEnd()`
