Hi all,

Just tried a port of a server daemon, compile/link worked fine, but on
startup I get "Addresses in the specified family cannot be used with this
socket" - WSAEAFNOSUPPORT.

Sample snippet of code follows, offending line marked with a >>>:

	myaddress.sin_port=htons(port);
	v=socket(AF_INET,SOCK_STREAM,0);
	if(v==-1)
	{
		fprintf(stderr,"(%d)",errno);
		perror("INET: socket, ");
		exit(1);
	}
	setsockopt(v,SOL_SOCKET,SO_REUSEADDR,&tmp,sizeof(tmp));
>>>	while(bind(v,(struct sockaddr *)&myaddress,sizeof(myaddress))<0)
	{
		if(errno != EADDRINUSE)
		{
			close(v);
			fprintf(stderr,"(%d)",errno);
			perror("INET: bind, ");
			exit(1);
		}
		printf("Address in use: Retrying...\n");
		sleep(5);
	}

The combination of address family/socket type/protocol seems OK to me -
Anyone got any ideas?

Thanks,

Austen
