+ * [Description]
  *
- * Description:
- *    Testcase to check the basic functionality of the epoll_ctl(2).
- * 1) when epoll_ctl(2) succeeds to register fd on the epoll instance and
- *    associates event with fd, epoll_wait(2) will get registered fd and
- *    event correctly.
- * 2) when epoll_ctl(2) succeeds to chage event which is related to fd,
- *    epoll_wait(2) will get chaged event correctly.
- * 3) when epoll_ctl(2) succeeds to deregister fd from the epoll instance
- *    epoll_wait(2) won't get deregistered fd and event.
+ * Check the basic functionality of the epoll_ctl:
  *
+ * - When epoll_ctl succeeds to register fd on the epoll instance and associates
+ * event with fd, epoll_wait will get registered fd and event correctly.
+ * - When epoll_ctl succeeds to change event which is related to fd, epoll_wait
+ * will get changed event correctly.
+ * - When epoll_ctl succeeds to deregister fd from the epoll instance epoll_wait
+ * won't get deregistered fd and event.
