Member Data Documentation

std::function<ScopedResource<PublishAcknowledgementHandle>)> Aws::Crt::Mqtt5::PublishReceivedEventData::acquirePublishAcknowledgement

Call this function within the OnPublishReceivedHandler callback to take manual control of the publish acknowledgement for this QoS 1 message, preventing the client from automatically sending a publish acknowledgement.

Returns a ScopedResource to a PublishAcknowledgementHandle that can be passed to Mqtt5Client::InvokePublishAcknowledgement() to send the publish acknowledgement to the broker.

Note

This function must be called within the OnPublishReceivedHandler callback. Calling it after the callback returns will return nullptr.

Only relevant for QoS 1 messages. Returns nullptr for QoS 0 messages.
