Restore a CUSP device vector previously acquired with VecCUSPGetArrayReadWrite().


PETSC_EXTERN PetscErrorCode VecCUSPRestoreArrayReadWrite(Vec v, CUSPARRAY **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This marks the host data as out of date.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 CUSP device vector. This pointer is invalid after VecCUSPRestoreArrayReadWrite() returns.

Fortran note

This function is not currently available from Fortran.
