I'm a little confused...What is this from?
The receive() call is supposed to return a pointer to the
message buffer in order for the caller to be able to free
the buffer (which may be redundant or silly, but that's
the way it is).
I don't know what "msg" is, since it's not declared in your
code snippet. And nothing is being sent (unless ProcessCmd()
does a send). The received message is pointed to by "pmsg"
and that is what is being processed and what should be returned
in all cases.
