# PetscSortInt
Sorts an array of `PetscInt` in place in increasing order.
## Synopsis
```
#include "petscsys.h"
PetscErrorCode PetscSortInt(PetscInt n, PetscInt X[])
```
Not Collective
## Input Parameters
- ***n -*** number of values
- ***X -*** array of integers
## Note
This function serves as an alternative to `PetscIntSortSemiOrdered()`, 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
`PetscIntSortSemiOrdered()`, `PetscSortReal()`, `PetscSortIntWithPermutation()`
