/**
 * Get a callback for calling the authProvider.checkAuth() method.
 * In case of rejection, redirects to the login page, displays a notification,

 * This is a low level hook. See those more specialized hooks
 * for common authentication tasks, based on useCheckAuth.
 *
 * @see useAuthenticated
 * @see useAuthState
 *
 * @returns {Function} checkAuth callback
 *
 * @example
 *
 * import { useCheckAuth } from 'react-admin';
 *
 * const MyProtectedPage = () => {
 *     const checkAuth = useCheckAuth();
 *     useEffect(() => {
 *         checkAuth().catch(() => {});
 *     }, []);
 *     return <p>Private content: EZAEZEZAET</p>
 * } // tip: use useAuthenticated() hook instead
 *
 * const MyPage = () => {
 *     const checkAuth = useCheckAuth();
 *     const [authenticated, setAuthenticated] = useState(true); // optimistic auth
 *     useEffect(() => {
 *         checkAuth({}, false)
 *              .then(() => setAuthenticated(true))
 *              .catch(() => setAuthenticated(false));
 *     }, []);
 *     return authenticated ? <Bar /> : <BarNotAuthenticated />;
 * } // tip: use useAuthState() hook instead
