PETSc version 3.17.5
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This marks the host data as out of date.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 Parameters
| 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.
