specifying an address, or a ctypes instance.
.. function:: POINTER(type)
.. function:: POINTER(type, /)
This factory function creates and returns a new ctypes pointer type. Pointer
types are cached and reused internally, so calling this function repeatedly is
cheap. *type* must be a ctypes type.

.. function:: pointer(obj)
.. function:: pointer(obj, /)
This function creates a new pointer instance, pointing to *obj*. The returned
object is of the type ``POINTER(type(obj))``.
Create a new pointer instance, pointing to *obj*.
The returned object is of the type ``POINTER(type(obj))``.
Note: If you just want to pass a pointer to an object to a foreign function
call, you should use ``byref(obj)`` which is much faster.
