Usage Notes
This API can be used in a multithreaded job to receive messages from a local data queue. It cannot be used
in a job that allows multiple threads to receive messages from a DDM data queue.
Application queueing time and resource usage time for data queue usage are recorded only for messages
that are received in the initial thread of a job.
