FileExists Method
Checks whether a vault item exists.
Syntax
ANSI (Cross Platform) int FileExists(const char* lpszFileName); Unicode (Windows) INT FileExists(LPCWSTR lpszFileName);
- (BOOL)fileExists:(NSString*)fileName;
#define MID_CBVAULT_FILEEXISTS 15 CBFSSTORAGE_EXTERNAL int CBFSSTORAGE_CALL CBFSStorage_CBVault_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);
Remarks
This method checks whether a vault item (file, directory, symbolic link, or alternate stream) with the specified FileName exists in the vault. If the specified vault item exists, this method returns true; otherwise it returns false.
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 Boolean 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.
