Boolean Objects
***************

Booleans in Python are implemented as a subclass of integers.  There
are only two booleans, ``Py_False`` and ``Py_True``.  As such, the
normal creation and deletion functions don't apply to booleans.  The
following macros are available, however.

int PyBool_Check(PyObject *o)

   Return true if *o* is of type ``PyBool_Type``.

   New in version 2.3.

PyObject* Py_False

   The Python ``False`` object.  This object has no methods.  It needs
   to be treated just like any other object with respect to reference
   counts.

PyObject* Py_True

   The Python ``True`` object.  This object has no methods.  It needs
   to be treated just like any other object with respect to reference
   counts.

Py_RETURN_FALSE

   Return ``Py_False`` from a function, properly incrementing its
   reference count.

   New in version 2.4.

Py_RETURN_TRUE

   Return ``Py_True`` from a function, properly incrementing its
   reference count.

   New in version 2.4.

PyObject* PyBool_FromLong(long v)
    Return value: New reference.

   Return a new reference to ``Py_True`` or ``Py_False`` depending on
   the truth value of *v*.

   New in version 2.3.
