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
