VecHIPRestoreArray

Restore a HIP device pointer previously acquired with VecHIPGetArray().

Synopsis

#include "petscvec.h"   
PETSC_EXTERN PetscErrorCode VecHIPRestoreArray(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This marks the host data as out of date.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 HIP device pointer. This pointer is invalid after VecHIPRestoreArray() returns.

Fortran note

This function is not currently available from Fortran.
