 \begin{cfuncdesc}{int}{PyObject_IsInstance}{PyObject *inst, PyObject *cls}
! Returns \code{1} if \var{inst} is an instance of the class \var{cls}
! or a subclass of \var{cls}, or \code{0} if not. On error, returns
! \code{-1} and sets an exception. If \var{cls} is a type object
! rather than a class object, \cfunction{PyObject_IsInstance()}
! returns \code{1} if \var{inst} is of type \var{cls}. If \var{cls}
! is a tuple, the check will be done against every entry in \var{cls}.
! The result will be \code{1} when at least one of the checks returns
! \code{1}, otherwise it will be \code{0}. If \var{inst} is not a class
! instance and \var{cls} is neither a type object, nor a class object,
! nor a tuple, \var{inst} must have a \member{__class__} attribute
! --- the class relationship of the value of that attribute with
! \var{cls} will be used to determine the result of this function.
