Libevent does support IPv6 for a long time, possibly since the very first public release. In order to make sure that your application is IPv6-ready, you need to double-check that you aren't using IPv4-only structures like sockaddr_in and functions like gethostbyaddr() / gethostbyname(). Use sockaddr_storage, getaddrinfo() and getnameinfo(). Libevent provides a bunch of portable wrappers, namely: - evutil_inet_pton(), evutil_inet_ntop() - evutil_addrinfo(), evutil_getaddrinfo(), evutil_freeaddrinfo(), evutil_gai_strerror(), Plus some helpers functions: - evutil_sockaddr_cmp() - evutil_parse_sockaddr_port() And some macros and types, see utils.h. Try to use libevent-provided wrappers as much as you can. They provide both portability and IPv6-readiness. -- Frank Denis - j [at] pureftpd.org - http://00f.net - Twitter: @jedisct1 *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
