Options for the MQTTAsync_disconnect call
char struct_id[4] |
The eyecatcher for this structure. Must be MQTD.
int struct_version |
The version number of this structure. Must be 0 or 1. 0 signifies no V5 properties
int timeout |
The client delays disconnection for up to this time (in milliseconds) in order to allow in-flight message transfers to complete.
MQTTAsync_onSuccess* onSuccess |
A pointer to a callback function to be called if the disconnect successfully completes. Can be set to NULL, in which case no indication of successful completion will be received.
MQTTAsync_onFailure* onFailure |
A pointer to a callback function to be called if the disconnect fails. Can be set to NULL, in which case no indication of unsuccessful completion will be received.
void* context |
A pointer to any application-specific context. The
the context pointer is passed to success or failure callback functions to provide access to the context information in the callback.
MQTTProperties properties |
MQTT V5 input properties
enum MQTTReasonCodes reasonCode |
Reason code for MQTTV5 disconnect
MQTTAsync_onSuccess5* onSuccess5 |
A pointer to a callback function to be called if the disconnect successfully completes. Can be set to NULL, in which case no indication of successful completion will be received.
MQTTAsync_onFailure5* onFailure5 |
A pointer to a callback function to be called if the disconnect fails. Can be set to NULL, in which case no indication of unsuccessful completion will be received.
