``p`` (:class:`bool`) [int]
Convert a C :c:expr:`int` to a Python :class:`bool` object.
+ Be aware that this format requires an ``int`` argument.
+ Unlike most other contexts in C, variadic arguments are not coerced to
+ a suitable type automatically.
+ You can convert another type (for example, a pointer or a float) to a
+ suitable ``int`` value using ``(x) ? 1 : 0`` or ``!!x``.
