GetSearchResultMetadataSize Method

Retrieves the size of the metadata associated with a vault item found during a search operation.

Syntax

ANSI (Cross Platform)
int64 GetSearchResultMetadataSize(int64 lSearchHandle);

Unicode (Windows)
LONG64 GetSearchResultMetadataSize(LONG64 lSearchHandle);
- (long long)getSearchResultMetadataSize:(long long)searchHandle;
#define MID_CBVAULT_GETSEARCHRESULTMETADATASIZE 47

CBFSSTORAGE_EXTERNAL int CBFSSTORAGE_CALL CBFSStorage_CBVault_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method retrieves the size of the metadata associated with a vault item (file, directory, symbolic link, or alternate stream) found via FindFirst/FindFirstByQuery/FindNext as part of the search operation identified by SearchHandle. Please refer to those methods' documentation for more information.

The metadata size of a vault item reflects the total size of all vault pages associated with it which do not contain actual file/stream data; this includes file tags (both internal and application-defined), index pages, B-trees, and all other "filesystem information".

The value passed for SearchHandle must be a search operation handle returned by FindFirst or FindFirstByQuery.

If metadata sizes were not requested as part of the specified search operation (by passing either 0 or a value including CBFSSTORAGE_FF_NEED_METADATA_SIZE for the FindFirst/FindFirstByQuery method's Flags parameter), this method will always return 0. Please refer to the documentation for these methods for more information.

Note: This method can only be called when Active is true.

Error Handling (C++)

This method returns a Long64 value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
