SaveSession Method

Saves session state data.

Syntax

ANSI (Cross Platform)
char* SaveSession();

Unicode (Windows)
LPWSTR SaveSession();
- (NSString*)saveSession;
#define MID_MQTT_SAVESESSION 11

IPWORKSMQ_EXTERNAL int IPWORKSMQ_CALL IPWorksMQ_MQTT_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method saves session state data currently held by the class, returning it as a string that can later be used to restore it. If the SessionStateFile configuration setting is set, the class will also write the session state data to that file (creating and/or overwriting it, as necessary).

Refer to CleanSession and RestoreSession for more information.

Error Handling (C++)

This method returns a String 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.
