RE: [Libevent-users] How do I get the client IP address?

["Kelly Brock" <Kerby@xxxxxxxxxxx>]

Hi Christian,

	As a question/suggestion, why are you not using the evconnlistener
api, it would give you all the data you desire.  I.e. the callback is of the
form:

void _acceptor( struct evconnlistener* el, evutil_socket_t fd, struct
sockaddr* addr, int addrLen, void* context )

	This api subset makes most things exceptionally easy for server
work.  I guess if you started with an example, it probably did the accept
directly but there are other examples which show the listener api in use
also which could get you started.
