Processes events from the internal message queue.
ANSI (Cross Platform) int DoEvents(); Unicode (Windows) INT DoEvents();
#define MID_MQTT_DOEVENTS 5 IPWORKSMQ_EXTERNAL int IPWORKSMQ_CALL IPWorksMQ_MQTT_Do(void *lpObj, int methid, int cparam, void *param, int cbparam, int64 *lpllVal);
When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Error Handling (C++)
This method returns a 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. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
