| 9 Name: beep | |
| 10 | |
| 11 Synopsis: | |
| 12 int beep(void); | |
| 13 int flash(void); | |
| 14 | |
| 15 Description: | |
| 16 beep() sounds the audible bell on the terminal, if possible; | |
| 17 if not, it calls flash(). | |
| 18 | |
| 19 flash() "flashes" the screen, by inverting the foreground and | |
| 20 background of every cell, pausing, and then restoring the | |
| 21 original attributes. | |
| 22 | |
| 23 Return Value: | |
| 24 These functions return OK. | |
