NAME
flash — flash the screen
SYNOPSIS
#include <curses.h>
int flash(void);
DESCRIPTION
The
flash()
function alerts the user. It flashes the screen, or if that is not possible,
it sounds the audible alarm on the terminal.
If neither signal is possible, nothing happens.
RETURN VALUE
The
flash()
function always returns OK.
ERRORS
No errors are defined.
APPLICATION USAGE
Nearly all terminals have an audible alarm, but only some can flash the
screen.
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
section is changed to indicate that the function always returns OK.
