Syntax

• C++

ANSI (Cross Platform)
int DirExists(const char* lpszRemoteDir);

Unicode (Windows)
INT DirExists(LPCWSTR lpszRemoteDir);

- (BOOL)dirExists:(NSString*)remoteDir;

#define MID_FTPCLIENT_DIREXISTS 13

SECUREBLACKBOX_EXTERNAL int SECUREBLACKBOX_CALL SecureBlackbox_FTPClient_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

Use this method to check if the RemoteDir exists on the server.

The test is performed by attempting to change the current directory to RemoteDir, and checking the response code returned by the server.

Note that this method will return false if the directory does exist but is not accessible for the client (e.g. due to a permission issue).

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.
