how to use multicast with Interniche

Hi

Thanks for your response, I have just a little problem.

I defined a dummy mcastlist() :

int dummy_mcastlist(struct in_multi * multi_ptr)
{
USE_ARG(multi_ptr);
return 0;
}

And I put this line just after Nichestack initialization

extern int dummy_mcastlist(struct in_multi * multi_ptr)
...
while (!iniche_net_ready)
    TK_SLEEP(1);
nets->n_mcastlist = dummy_mcastlist;

Compilation is OK but setsockopt() fails on MULTICAST_IF :

   memset(&local_addr,0,sizeof(local_addr)); 
    local_addr.sin_family = AF_INET;
    local_addr.sin_port = htons(USED_PORT);
    local_addr.sin_addr.s_addr = htonl(INADDR_ANY);    
    if((setsockopt (sock, IPPROTO_IP, IP_MULTICAST_IF,(char*) &local_addr,sizeof(local_addr)))<0)
    {
    fprintf(stderr,"multicast_if failed\n");}

I am not able to send multicast packet.

What's wrong?

Have I to do some changes in allports.c?

Thanks.

Mikael.
