SUCCESS or any Natural Access or service-specific error code.
The dispatcher invokes xxxAttachServiceManager when a Natural Access queue is created and the service manager is listed in the arguments to ctaCreateQueue. Only service managers in this list are attached and are available to be opened on the queue.
queuecontext provides a way for the service manager to allocate a device object that it will associate with the queue. If the queuecontext is not needed, queuecontext can have NULL assigned as its value.
Wait objects should be registered with the dispatcher if the managed resource is multiplexed with this function.
