Gets the DVRSink buffer information associated with the specified buffer file index.
|C||HRESULT ILMDVRSink_GetBufferInfo(pILMDVRSink, nBufferIndex, pszFileName, pnUsefulSize, pnFileSize, pnPlayIndex, pnFlags)|
|C++||HRESULT GetBufferInfo(nBufferIndex, pszFileName, pnUsefulSize, pnFileSize, pnPlayIndex, pnFlags)|
Pointer to an ILMDVRSink interface.
The 0-based index of the buffer file for which to get information.
A pointer to a string type that will receive the filename of the related buffer recording file.
A pointer to a double type that will receive the used file size of the current recording chunk file.
A pointer to a double type that will receive the physical file size of the current recording chunk file.
A pointer to a long type that will receive the index in playing order (the first index might not be 0, but all files should have sequential and incrementing indexes after the first index value).
A pointer to a long type that will receive a DVRBufferFlagConstant setting. Possible values are:
|S_OK||The function was successful.|
|E_INVALIDARG||Buffer index supplied is outside the range of currently valid indexes.|
|LTMM_E_DVR_NO_RECORDINGS||No .LRC recording files exist.|
|E_OUTOFMEMORY||A memory allocation error occurred when attempting to allocate storage for the buffer filename string.|
|<>S_OK||An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.|
