Hi,
I am developing a GTK+ and Cairo application over DirectFB and it is running
over Slackware.
I've tried many maaaany ways of make the machine beep through the
piezoelectric buzzer and the only succesfull way I got is:
int console = open("/dev/tty10", O_WRONLY);
if (console == -1)
{
theLog->error ("Could not open device for beep.");
return;
}
ioctl(console, KDMKTONE, (250<<16)+400);
usleep(250000);
My problem is that it only sounds (many times as it had to beep during the
application) after closing the DFB application.
How can I make the system beep during the application? I think there is
something related to the /dev/tty10 and the DirectFB, but no /dev/ else
beeps...I have no more clues to make this happen.
Already tried:
printf ("\a"); //and all variants of this one. Also with std::cout.
gdk_beep();
and tried many /dev/* in the previous function.
Thank you very much.
