IStreamBufferCapture::BeginPermanentRecording (Windows CE 5.0)
This method is used by a client DVR application to initiate a permanent recording. If the previous recording was temporary, then this method converts that temporary recording to a permanent recording. If the previous recording was permanent then the call to this method represents a transition from one permanent recording to another.
HRESULT BeginPermanentRecording( LONGLONG hyRetainedSizeInMilliseconds, LONGLONG* phyActualRetainedSizeInMillisecs);
Parameters
hyRetainedSizeInMilliseconds
[in] A LONGLONG value that specifies the amount time, in milliseconds, from the end of a temporary recording to transfer to the beginning of a new permanent recording. This parameter is only meaningful if the previous recording was temporary.If the temporary recording is shorter than hyRetainedSizeInMilliseconds then the entire temporary recording is converted to a permanent recording. The new permanent recording created from a temporary recording will take on the name of the temporary recording.
phyActualRetainedSizeInMillisecs
[out] A pointer to a LONGLONG value that identifies how many milliseconds, if any, from the previous temporary recording were transferred to the beginning of the new permanent recording.

| Value | Description |
|---|---|
| E_FAIL | The method was unable to create the new file |
| S_OK | The method was successful |
When beginning a permanent recording, the client will call BeginPermanentRecording(). Then the client must ask the Writer's IFileSinkFilter2 to obtain the name of the new recording.
