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
