Generally, if I'm going to need to iterate over all of the active (sessions/events/whatever) in an application, I do in fact keep them in a linked list of some kind. >.

Internally, libevent has the ability to iterate over all events, but it doesn't have any list of buferevents it can iterate over. hope this helps, -- Nick *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
