Personally, my first approach would be to do it with something closer to a reference count: in the data associated with each bufferevent, remember the number of messages it has outstanding, and don't actually free the bufferevent until it has received a close _and_ it has no messages waiting. Alternatively, you could use a weak-reference style system where instead of having a pointer to the bufferevent, each Message would get a pointer to a a "weak reference" object that either had a pointer to the bufferevent, or a NULL pointer to indicate that the bufferevent had gone away. You'd free these objects once the bufferevent had no more outstanding messages. Or you could keep a linked list of messages for each bufferevent, and, when about to free the bufferevent, first cancel each message or mark it as having to bufferevent to send to. There are probably other ways too. hth, -- Nick *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
