# VecHIPPlaceArray
Allows one to replace the GPU array in a vector with a GPU array provided by the user. This is useful to avoid copying an array into a vector. 
## Synopsis
```
#include "petscvec.h"   
PetscErrorCode VecHIPPlaceArray(Vec vin, const PetscScalar a[])
```
Not Collective; No Fortran Support


## Input Parameters

- ***vec -*** the vector
- ***array -*** the GPU array





## Notes
You can return to the original GPU array with a call to `VecHIPResetArray()`
It is not possible to use `VecHIPPlaceArray()` and `VecPlaceArray()` at the
same time on the same vector.

`vec` does not take ownership of `array` in any way. The user must free `array` themselves
but be careful not to do so before the vector has either been destroyed, had its original
array restored with `VecHIPResetArray()` or permanently replaced with
`VecHIPReplaceArray()`.
