In my projects/ifnet a similar functions exist:
/*
* Traversing through interface address lists.
*/
typedef void ifaddr_cb_t(void *, struct sockaddr *, struct sockaddr *,
struct sockaddr *);
typedef void ifmaddr_cb_t(void *, struct sockaddr *);
void if_foreach_addr(if_t, ifaddr_cb_t, void *);
void if_foreach_maddr(if_t, ifmaddr_cb_t, void *);
/*
* Methods for drivers to access interface unicast and multicast
* addresses. Driver do not know 'struct ifaddr' neither 'struct ifmultiaddr'.
*/
void
if_foreach_addr(if_t ifp, ifaddr_cb_t cb, void *cb_arg)
{
struct ifaddr *ifa;
IF_ADDR_RLOCK(ifp);
TAILQ_FOREACH(ifa, &ifp->if_addrhead, ifa_link)
(*cb)(cb_arg, ifa->ifa_addr, ifa->ifa_dstaddr,
ifa->ifa_netmask);
IF_ADDR_RUNLOCK(ifp);
}
void
if_foreach_maddr(if_t ifp, ifmaddr_cb_t cb, void *cb_arg)
{
struct ifmultiaddr *ifma;
IF_ADDR_RLOCK(ifp);
TAILQ_FOREACH(ifma, &ifp->if_multiaddrs, ifma_link)
(*cb)(cb_arg, ifma->ifma_addr);
IF_ADDR_RUNLOCK(ifp);
}
Do you mind if I adopt head to them instead of if_multi_apply()?
