CURSES

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. 

SEE ALSO

beep(), <curses.h>. 

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.
