# VecRestoreArrayReadF90
Restores a readonly vector to a usable state after a call to `VecGetArrayReadF90()`. 
## Synopsis
```
VecRestoreArrayReadF90(Vec x,{Scalar, pointer :: xx_v(:)},integer ierr)
```
Logically Collective


## Input Parameters

- ***x -*** vector
- ***xx_v -*** the Fortran pointer to the array



## Output Parameter

- ***ierr -*** error code



## Example of Usage
```none
#include <petsc/finclude/petscvec.h>
    use petscvec

    PetscScalar, pointer :: xx_v(:)
    ....
    call VecGetArrayReadF90(x,xx_v,ierr)
    a = xx_v(3)
    call VecRestoreArrayReadF90(x,xx_v,ierr)
```
