| 10 | ### Synopsis |
||
| 11 | |||
| 12 | int beep(void); |
||
| 13 | int flash(void); |
||
| 14 | |||
| 15 | ### Description |
||
| 16 | |||
| 17 | beep() sounds the audible bell on the terminal, if possible; if not, |
||
| 18 | it calls flash(). |
||
| 19 | |||
| 20 | flash() "flashes" the screen, by inverting the foreground and |
||
| 21 | background of every cell, pausing, and then restoring the original |
||
| 22 | attributes. |
||
| 23 | |||
| 24 | ### Return Value |
||
| 25 | |||
| 26 | These functions return ERR if called before initscr(), otherwise OK. |
||
| 27 | |||
| 28 | ### Portability |
