For a non-controlling process, is `ioctl(fd, TIOCNOTTY)` the same as `close(fd)`?

                          Assume a session has a controlling terminal.
If a process in the session that is not the session leader, calls ioctl(fd, TIOCNOTTY),  is it correct that it only closes the fd for itself? Is it the same as close(fd)?

Thanks.
