IStreamBufferSink2::UnlockProfile
This topic applies to Windows XP Service Pack 2 only.
The UnlockProfile method unlocks the Stream Buffer Sink filter's profile. After the profile is unlocked, you can change the name of the stub file.
Syntax
HRESULT UnlockProfile(void);
Parameters
This method takes no parameters.
Return Values
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Value | Description |
| S_FALSE | The profile is not currently locked. |
| S_OK | The method succeeded. |
Remarks
The filter graph must be stopped when you call this method. If the recording session has not been started, this method invalidates the recording. To re-create the recording, call IStreamBufferSink::LockProfile again. If the profile is not already locked, the Unlock method has no effect and returns S_FALSE.
If the graph is running, stopping the graph automatically unlocks the profile without the need to call UnlockProfile.
