+   This function returns a memoryview object that references the
+   memory starting at *address* up to (but not including) *address +
+   size*.  If *allow_write* is set to a truthy value then the
+   memoryview object is mutable.
+
+   This function is similar to :funct:`string_at` with the key difference
+   of not making a copy of the specified memory.
