31.SH NAME
Steve Kondikae271bc2015-11-15 02:50:53 +010032\fBbeep\fR, \fBflash\fR \- \fBcurses\fR bell and screen flash routines
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +053033.SH SYNOPSIS
34\fB#include <curses.h>\fR
35.PP
36\fBint beep(void);\fR
37.br
38\fBint flash(void);\fR
39.br
40.SH DESCRIPTION
41The \fBbeep\fR and \fBflash\fR routines are used to alert the terminal user.
42The routine \fBbeep\fR sounds an audible alarm on the terminal, if possible;
43otherwise it flashes the screen (visible bell). The routine \fBflash\fR
44flashes the screen, and if that is not possible, sounds the alert. If neither
45alert is possible, nothing happens. Nearly all terminals have an audible alert
46(bell or beep), but only some can flash the screen.
47.SH RETURN VALUE
48These routines return \fBOK\fR if they succeed in beeping or flashing,
49\fBERR\fR otherwise.
50.SH EXTENSIONS
51SVr4's beep and flash routines always returned \fBOK\fR, so it was not
52possible to tell when the beep or flash failed.
53.SH PORTABILITY
54These functions are described in the XSI Curses standard, Issue 4.
55Like SVr4, it specifies that they always return \fBOK\fR.
56.SH SEE ALSO
57\fBcurses\fR(3X)
