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".

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.

Py_RETURN_TRUE

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

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*.
