GetFileMetadataSize Method

Retrieves the size of the metadata associated with a vault item.

Syntax

ANSI (Cross Platform)
int64 GetFileMetadataSize(const char* lpszFileName);

Unicode (Windows)
LONG64 GetFileMetadataSize(LPCWSTR lpszFileName);
- (long long)getFileMetadataSize:(NSString*)fileName;
#define MID_CBVAULT_GETFILEMETADATASIZE 27

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 the vault item (file, directory, symbolic link, or alternate stream) specified by FileName.

A vault item's metadata size 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 FileName must be a vault-local absolute path.

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.
