VecCUDARestoreArray
Restore a CUDA device pointer previously acquired with VecCUDAGetArray(). 
Synopsis
#include "petscvec.h"   
PETSC_EXTERN PetscErrorCode VecCUDARestoreArray(Vec v, PetscScalar **a)
This marks the host data as out of date.  Subsequent access to the
vector data on the host side with for instance VecGetArray() incurs a
data transfer.
Input Parameter
|  | v | - the vector | 
|  | a | - the CUDA device pointer.  This pointer is invalid after
VecCUDARestoreArray() returns. | 
Fortran note
This function is not currently available from Fortran.
