The GetCaps method retrieves the capabilities of the DirectSound buffer object.
Syntax
HRESULT GetCaps(
LPDSBCAPS pDSBufferCaps
);
Parameters
pDSBufferCaps
Address of a DSBCAPS structure to contain the capabilities of this sound buffer.
Return Values
If the method succeeds, the return value is DS_OK.
If the method fails, the return value may be DSERR_INVALIDPARAM.
Remarks
The DSBCAPS structure contains similar information to the DSBUFFERDESC structure passed to the IDirectSound8::CreateSoundBuffer method, with some additional information. This additional information can include the buffer's location, either in hardware or software, and performance measures.
The flags specified in the dwFlags member of the DSBCAPS structure are the same flags used by the DSBUFFERDESC structure. The only difference is that in the DSBCAPS structure, either DSBCAPS_LOCHARDWARE or DSBCAPS_LOCSOFTWARE will be specified according to the location of the buffer memory. In the DSBUFFERDESC structure, these flags are optional and, depending on which flag is specified, force the buffer to be located in either hardware or software.
