Platform SDK: Debugging and Error Handling |
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 DWORD dwDuration // sound duration );
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.
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.
Windows NT/2000: Requires Windows NT 3.1 or later.
Windows 95/98: Requires Windows 95 or later.
Header: Declared in Winbase.h; include Windows.h.
Library: Use Kernel32.lib.
