-    Gives the SYCL(TM) USM pointer type, using ``sycl::get_pointer_type``,

-       ptr: int
-          A pointer stored as size_t Python integer.

-       'unknown' if the pointer does not represent USM allocation made using
-       the given context. Otherwise, returns 'shared', 'device', or 'host'
-       type of the allocation.
