Derek, Has there been much though put into thread safety aspects of
the DUM? I don't use the stack in Multi-threaded mode -
but I am using 1 thread to run the select/process loop and other threads (ie. One
per SIP/RTP port) that can call the send/end/makexxx methods of the various
Session objects (just Invite session for now). I am concerned that some
of these calls, could end up deleting memory that may be in use by the main
process loop. For example: What if I call send on
ClientInviteSession to send a CANCEL message - this deletes the
ClientInviteSession object itself (ie. delete this). But what if the main
thread is processing an inbound message destined for the ClientInviteSession at
the same time and is accessing the session object? What assumptions are made by the DUM as far as threading is
concerned? What is the final goal as far as threading is concerned? Thanks, Scott
