IWMProfile3::CreateNewBandwidthSharing method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The CreateNewBandwidthSharing method creates a new bandwidth sharing object.

Syntax

HRESULT CreateNewBandwidthSharing(
  [out] IWMBandwidthSharing **ppBS
);

Parameters

[out] ppBS

Pointer to a variable that receives the address of the IWMBandwidthSharing interface of the new object.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
The method succeeded.
E_INVALIDARG
ppBS is NULL.
E_OUTOFMEMORY
The method is unable to allocate memory for the new object.

Remarks

To make use of the bandwidth sharing object, you must add it to the profile with a call to AddBandwidthSharing. A bandwidth sharing object cannot exist on its own. If you release the profile object without adding the bandwidth sharing object to the profile, you will lose the bandwidth sharing object.

You must configure the bandwidth sharing object before you use AddBandwidthSharing to include the bandwidth sharing object in the profile. For more information about configuring bandwidth sharing objects, see IWMBandwidthSharing Interface.
