Sending partition buffers to message queue..

Hello all,

I have a question concerning sending messages to a queue:

I want to send a message from one thread to another one by using a
message queue. The message to be sent should be allocated from a fast
memory pool (hence a partition block seems to be more efficient instead
of the heap by using malloc).

My question: Is it possible to use buffers allocated from a partition
for this mechanism? If yes, does RTEMS free the allocated memory after
the message has been received by the second thread? I learned that the
OS copies the message in another buffer than the original one.

Thanks in advance,
Samuel.
