DirectSoundCaptureCreate8
The DirectSoundCaptureCreate8 function creates and initializes an object that supports the IDirectSoundCapture8 interface. Although the older DirectSoundCaptureCreate function can also be used to obtain the IDirectSoundCapture8 interface, the object created by that function cannot be used to create capture buffers that support the IDirectSoundCaptureBuffer8 interface.
HRESULT DirectSoundCaptureCreate8(
LPCGUID lpcGUID,
LPDIRECTSOUNDCAPTURE8 * lplpDSC,
LPUNKNOWN pUnkOuter
)
Parameters
- lpcGUID
-
Address of the GUID that identifies the sound capture device. The value of this parameter must be one of the GUIDs returned by DirectSoundCaptureEnumerate, or NULL for the default device, or one of the following values.
Value Description DSDEVID_DefaultCapture System-wide default audio capture device. DSDEVID_DefaultVoiceCapture Default voice capture device. - lplpDSC
- Address of a variable to receive an IDirectSoundCapture8 interface pointer.
- pUnkOuter
- Address of the controlling object's IUnknown interface for COM aggregation. Must be NULL, because aggregation is not supported.
