C Syntax	HRESULT ILMDVRSink_GetBufferTotalSize(pILMDVRSink, nFolderIndex, uFlags, pnFiles, pnTotalFileSize)
C++ Syntax	HRESULT GetBufferTotalSize(nFolderIndex, uFlags, pnFiles, pnTotalFileSize)

ILMDVRSink *pILMDVRSink ;	/* pointer to an interface */
long nFolderIndex;	/* 0-based index of buffer location */
long uFlags;	/* flags */
long * pnFiles;	/* pointer to total number of files */
double * pnTotalFileSize;	/* pointer to total file size */

Gets the total size or actual size of all of the buffer (.LRC) files for the specified buffer folder.

Parameter	Description
pILMDVRSink	Pointer to an ILMDVRSink interface.
nFolderIndex	The 0-based index of the desired buffer folder.
uFlags	Flag specifying how to calculate the total size. Values can be: DVRGetTotalSize_Actual = 0x0000 DVRGetTotalSize_Allowed = 0x0001
pnFiles	Total number of files included in the buffer size calculation.
pnTotalFileSize	The total calculated buffer file size.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

Pass the DVRGetTotalSize_Allowed flag value to request the total allowable buffer file size OR pass the DVRGetTotalSize_Actual flag value to request the actual used total file size.

S_OK if successful, otherwise a return code indicating the reason for failure:

E_UNEXPECTED = Starting offset not found.

DISP_E_BADINDEX = Index supplied is outside the range of currently valid indexes.

LTMM_E_DVR_NO_RECORDINGS = No .LRC recording files exist.

E_INVALIDARG = Either the number of files or file size specified is not valid.
