Constructor & Destructor Documentation

delivery_token() [1/3]

mqtt::delivery_token::delivery_token ( iasync_client & cli )

inline

Creates an empty delivery token connected to a particular client.

Parameters

cli	The asynchronous client object.

delivery_token() [2/3]

mqtt::delivery_token::delivery_token ( iasync_client & cli, const_message_ptr msg )

inline

Creates a delivery token connected to a particular client.

Parameters
