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
| );
|
|
Parameters
dwFreq
Windows NT:
Specifies the frequency, in hertz, of the sound. This parameter must be in the
range 37 through 32,767 (0x25 through 0x7FFF).
Windows 95:
The parameter is ignored.
dwDuration
Windows NT:
Specifies the duration, in milliseconds, of the sound.
Windows 95:
The parameter is ignored.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
Windows 95:
The Beep function ignores the dwFreq and dwDuration parameters. On computers with a sound card, the function plays the default
sound event. On computers without a sound card, the function plays the standard
system beep.
