.SH DESCRIPTION
.sp
.LP
The \fBbeep()\fR and \fBflash()\fR functions produce an audio and visual alarm
on the terminal, respectively.  If the terminal has the capability,
\fBbeep()\fR sounds a bell or beep and  \fBflash()\fR flashes the screen.  One
alarm is substituted for another if the terminal does not support the
capability called (see  \fBterminfo\fR(4) \fBbel\fR and \fBflash\fR
capabilities). For example, a call to \fBbeep()\fR for a terminal without that
capability  results in a flash.
.SH RETURN VALUES
