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`.
 | 
						|
 | 
						|
 | 
						|
.. 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*.
