ExtensionCmd Method

Sends an extension command to the server.

Syntax

• C++
• Objective-C
• C

ANSI (Cross Platform)
char* ExtensionCmd(const char* lpszExtn, const char* lpDataBuffer, int lenDataBuffer, int *lpSize = NULL);

Unicode (Windows)
LPSTR ExtensionCmd(LPCWSTR lpszExtn, LPCSTR lpDataBuffer, INT lenDataBuffer, LPINT lpSize = NULL);

- (NSData*)extensionCmd:(NSString*)extn :(NSData*)dataBuffer;

#define MID_SFTPCLIENT_EXTENSIONCMD 17

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

Remarks

Use this method to send an extension command to the SFTP server. Provide the extension type via the Extn parameter, and the request body via the DataBuffer parameter.

Upon completion of the command, the method returns the response as received from the server.

Error Handling (C++)

This method returns a Byte Array value (with length lpSize); 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.
