The GetVolume method retrieves the volume of the buffer.
Syntax
HRESULT GetVolume(
LPLONG plVolume
);
Parameters
plVolume
Address of a variable that receives the attenuation, in hundredths of a decibel. See Remarks.
Return Values
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be one of the following error values:
| Return code |
| DSERR_CONTROLUNAVAIL |
| DSERR_INVALIDPARAM |
| DSERR_PRIOLEVELNEEDED |
Remarks
The return value is between DSBVOLUME_MAX and DSBVOLUME_MIN. These values are defined as 0 and –10,000, respectively. The value DSBVOLUME_MAX represents the original, unadjusted volume of the sound. The value DSBVOLUME_MIN indicates an audio volume attenuated by 100 dB, which, for practical purposes, is silence.
