Action of rtems_message_queue_send

[groups at chichak.ca (Andrei Chichak)]

When sending a message to a queue, does the message data get copied 
into the message queue or does the queue point at the original data items?

The reason that I ask is that if the data is not copied, alteration 
of the message data items before the message gets received will pick 
up the new values. (I've seen this in another /OS )
