void sofia_glue_get_addr(msg_t *msg, char *buf, size_t buflen, int *port)
{
su_addrinfo_t *addrinfo = msg_addrinfo(msg);
if (buf) {
get_addr(buf, buflen, addrinfo->ai_addr, addrinfo->ai_addrlen);
}
if (port) {
*port = get_port(addrinfo->ai_addr); }
}
Thats what we use on a msg_t to extract this info.
