ble alarm on the terminal. If neither signal is possible, nothing happens.
RETURN VALUE
The
flash() function always returns OK.
ERRORS

CHANGE HISTORY
First released in X/Open Curses, Issue 4.
In previous issues, this function was included in the entry for
beep(). It is moved to its own entry in
X/Open Curses, Issue 4, the argument list is explicitly declared as void, and the RETURN VALUE sec-
tion is changed to indicate that the function always returns OK.
