Name: beep
Synopsis:
int beep(void);
int flash(void);
Description:
beep() sounds the audible bell on the terminal, if possible;
if not, it calls flash().
flash() "flashes" the screen, by inverting the foreground and
background of every cell, pausing, and then restoring the
original attributes.
Return Value:
These functions return OK.
Portability X/Open BSD SYS V
beep Y Y Y
flash Y Y Y
