# PetscSortMPIInt
Sorts an array of `PetscMPIInt` in place in increasing order. 
## Synopsis
```
#include "petscsys.h"  
PetscErrorCode PetscSortMPIInt(PetscInt n, PetscMPIInt X[])
```
Not Collective


## Input Parameters

- ***n  -*** number of values
- ***X  -*** array of integers





## Note
This function serves as an alternative to PetscMPIIntSortSemiOrdered(), and may perform faster especially if the array
is completely random. There are exceptions to this and so it is __highly__ recommended that the user benchmark their
code to see which routine is fastest.


## See Also
 `PetscMPIIntSortSemiOrdered()`, `PetscSortReal()`, `PetscSortIntWithPermutation()`

## Level
