Disconnected Event

Fired when a connection is closed.

Syntax

ANSI (Cross Platform)
virtual int FireDisconnected(MQTTDisconnectedEventParams *e);
typedef struct {
int StatusCode;
const char *Description; int reserved; } MQTTDisconnectedEventParams; Unicode (Windows) virtual INT FireDisconnected(MQTTDisconnectedEventParams *e);
typedef struct {
INT StatusCode;
LPCWSTR Description; INT reserved; } MQTTDisconnectedEventParams;
- (void)onDisconnected:(int)statusCode :(NSString*)description;
#define EID_MQTT_DISCONNECTED 3

virtual INT IPWORKSMQ_CALL FireDisconnected(INT &iStatusCode, LPSTR &lpszDescription);

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the TCP/IP subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.
