Синопсис (Synopsis)
#include <curses.h>
int beep(void);
int flash(void);
Описание (Description)
The beep
and flash
routines are used to alert the terminal user.
The routine beep
sounds an audible alarm on the terminal, if
possible; otherwise it flashes the screen (visible bell). The
routine flash
flashes the screen, and if that is not possible,
sounds the alert. If neither alert is possible, nothing happens.
Nearly all terminals have an audible alert (bell or beep), but
only some can flash the screen.
Возвращаемое значение (Return value)
These routines return OK
if they succeed in beeping or flashing,
ERR
otherwise.
Расширения (Extensions)
SVr4's beep and flash routines always returned OK
, so it was not
possible to tell when the beep or flash failed.
Портативность (Portability)
These functions are described in the XSI Curses standard, Issue
4. Like SVr4, it specifies that they always return OK
.
