Boolean Objects
---------------
Booleans in Python are implemented as a subclass of integers. There are only
two booleans, :const:`Py_False` and :const:`Py_True`. As such, the normal
creation and deletion functions don't apply to booleans. The following macros
are available, however.
.. c:function:: int PyBool_Check(PyObject *o)
Return true if *o* is of type :c:data:`PyBool_Type`. This function always
succeeds.
.. c:var:: 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.
.. c:var:: 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.
.. c:macro:: Py_RETURN_FALSE
Return :const:`Py_False` from a function, properly incrementing its reference
count.
.. c:macro:: Py_RETURN_TRUE
Return :const:`Py_True` from a function, properly incrementing its reference
count.
.. c:function:: PyObject* PyBool_FromLong(long v)
Return a new reference to :const:`Py_True` or :const:`Py_False` depending on the
truth value of *v*.
