public virtual qa_int getQueueDepth(
     qa_const_string address,
    qa_short filter
)

The number of messages in the queue, or -1 if an error occurs.

The incoming depth of the queue is the number of incoming messages which have not been received (for example, using QAManagerBase::getMessage). The outgoing depth of a queue is the number of outgoing messages (including uncommitted) that have not been transmitted to the server.

If getQueueDepth is called with the LOCAL filter and a queue is specified, it returns the number of unreceived local messages that are addressed to that queue. If a queue is not specified, it returns the total number of unreceived local messages in the message store, excluding system messages.
