FWICT, your code isn't really simulating a cutoff: the file descriptor allocated for the client bufferevent at line 128 is never actually closed, since you neither close the socket nor free the bufferevent. (There's a bufferevent_free call in client_event_cb, but it will never get invoked, unless the server closes the connection or causes an error, I think.) Thus, sockfd won't get automatically freed until the entire process exits: just exiting the client thread isn't enough to make anything happen to it. hth, -- Nick *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
