I'm not sure I follow.  If you want to call those functions, set the
VecType to VECCUDA.  For many examples, this is done via the run-time
option

  -dm_vec_type cuda

(see many examples in the PETSc source tree).  If you're trying to copy
the implementation into your code without using PETSc, you're on your
own.
