Beep
The Beep
function generates simple tones on the speaker. The function is synchronous; it
does not return control to its caller until the sound finishes.
BOOL Beep(
|
DWORD dwFreq, |
// sound frequency,
in hertz |
|
DWORD dwDuration |
// sound duration,
in milliseconds |
|
); |

The Beep
function ignores the dwFreq and dwDuration parameters. On
computers with a sound card, the function plays the default sound event. On
