DESCRIPTION
The
beep() and
flash() functions produce an audio and visual alarm on
the terminal, respectively. If the terminal has the capability,
beep() sounds a bell or beep and
flash() flashes the screen. One
alarm is substituted for another if the terminal does not support the
capability called (see
terminfo(5) bel and
flash capabilities). For
example, a call to
beep() for a terminal without that capability
results in a flash.
RETURN VALUES
These functions always return
OK.
ERRORS
None.
