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.
