Hello all,

[NOTE:  I recently subscribed to this newsgroup, and my reader only retrieved
the last dozen or so messages.  None of these posts contained a reference to a
group FAQ.  If this question is answered by a FAQ, please advise.  Thanks.]

	I have a problem in which I would like to non-destructively unpack a
PVM receive buffer.  The application contains an event handler that invokes
(one or more) callback functions in response to receiving a PVM message.
However, the callback functions are responsible for unpacking the PVM receive
buffer.  Consequently, the current implementation may only use one callback.
We would like to map multiple callbacks to a single PVM message.

	Is there a way to unpack a PVM receive buffer non-destructively?
Please note that making the event handler perform the unpack and invoke the
callbacks with the appropriate parameters is not an acceptable solution for
this application.

	Many thanks,
