IWMProfile::CreateNewMutualExclusion 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 It has been superseded by Source Reader and Sink Writer.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 CreateNewMutualExclusion method creates a mutual exclusion object. Mutual exclusion objects are used to specify a set of streams, only one of which can be output at a time.
Syntax
HRESULT CreateNewMutualExclusion(
[out] IWMMutualExclusion **ppME
);
Parameters
[out] ppME
Pointer to a pointer to the IWMMutualExclusion interface of the new mutual exclusion object.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
The ppME parameter is NULL. |
Remarks
This creation method is included as a method to this interface, rather than as an independent function. For clarity, it is not possible to have a mutual exclusion object other than as an element of a profile.
After the application has created the mutual exclusion object, it must be configured and then AddMutualExclusion must be called to add the mutual exclusion to the profile.
