# VecHIPRestoreArrayWrite
Restore a HIP device pointer previously acquired with `VecHIPGetArrayWrite()`. 
## Synopsis
```
#include <petscvec.h> 
PetscErrorCode VecHIPRestoreArrayWrite(Vec v, PetscScalar **a)
```
Not Collective; Asynchronous; No Fortran Support


## Input Parameters

- ***v -*** the vector
- ***a -*** the HIP device pointer.  This pointer is invalid after `VecHIPRestoreArrayWrite()` returns.





## Note
Data on the host will be marked as out of date. Subsequent access of the data on the host
side e.g. with `VecGetArray()` will incur a device to host data transfer.
