Type Definition paho_mqtt_sys::MQTTAsync_onSuccess5

type MQTTAsync_onSuccess5 = Option<unsafe extern "C" fn(context: *mut c_void, response: *mut MQTTAsync_successData5)>;

This is a callback function, the MQTT V5 version of ::MQTTAsync_onSuccess. The client application must provide an implementation of this function to enable asynchronous notification of the successful completion of an API call. The function is registered with the client library by passing it as an argument in ::MQTTAsync_responseOptions.

Note: Neither MQTTAsync_create() nor MQTTAsync_destroy() should be called within this callback. @param context A pointer to the context value originally passed to ::MQTTAsync_responseOptions, which contains any application-specific context. @param response Any success data associated with the API completion.
