Parameters

theQoS	The quality of service parameters for this subscription.
subscriber	The subscriber's proxy. This proxy cannot be null.
response	The response callback. The Ice runtime calls this function from an Ice thread pool thread. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function. It accepts: The per-subscriber publisher proxy. This proxy is never null.
exception	The exception callback. The Ice runtime calls this function from an Ice thread pool thread. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function.
sent	The sent callback. The Ice runtime calls this function when the request is accepted by the transport. When the request is accepted synchronously, the Ice runtime calls this function from the current thread and passes true as argument. When the request is accepted asynchronously, the Ice runtime calls this function from an Ice thread pool thread and passes false as argument. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function in the asynchronous case.
context	The request context.

Returns

A function that can be called to cancel the invocation locally.
