## Detailed Description

Options for the MQTTAsync_disconnect call

## Field Documentation

## ◆ struct_id

char struct_id[4]

The eyecatcher for this structure. Must be MQTD.

## ◆ struct_version

int struct_version

The version number of this structure. Must be 0 or 1. 0 signifies no V5 properties

## ◆ timeout

int timeout

The client delays disconnection for up to this time (in milliseconds) in order to allow in-flight message transfers to complete.

## ◆ onSuccess

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.

## ◆ onFailure

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.

## ◆ context

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.

## ◆ properties

MQTTProperties properties

MQTT V5 input properties

## ◆ reasonCode

enum MQTTReasonCodes reasonCode

Reason code for MQTTV5 disconnect

## ◆ onSuccess5

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.

## ◆ onFailure5

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.
