There are only 9two booleans, :const:`Py_False` and :const:`Py_True`. As such, the normal 10creation and deletion functions don't apply to booleans. The following macros 11are available, however. 12 13 14.. c:function:: int PyBool_Check(PyObject *o) 15 16 Return true if *o* is of type :c:data:`PyBool_Type`. 17 18 19.. c:var:: PyObject* Py_False 20 21 The Python ``False`` object. This object has no methods. It needs to be 22 treated just like any other object with respect to reference counts. 23 24 25.. c:var:: PyObject* Py_True 26 27 The Python ``True`` object. This object has no methods. It needs to be treated 28 just like any other object with respect to reference counts. 29 30 31.. c:macro:: Py_RETURN_FALSE 32 33 Return :const:`Py_False` from a function, properly incrementing its reference 34 count. 35 36 37.. c:macro:: Py_RETURN_TRUE 38 39 Return :const:`Py_True` from a function, properly incrementing its reference 40 count. 41 42 43.. c:function:: PyObject* PyBool_FromLong(long v) 44 45 Return a new reference to :const:`Py_True` or :const:`Py_False` depending on the 46 truth value of *v*. 47
