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{inst}
is not a class instance and \var{cls} is neither a type object or
class object, \var{inst} must have a \member{__class__} attribute
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.

Subclass determination is done in a fairly straightforward way, but
