hello cygwin,
I think there is a bug in your networking code. Sendto can't send
packet to AF_UNIX socket reporting "Addresses in the specified family
cannot be used with this socket").
Socket is creating with this code:
####################################################################################
if ((incoming_pipe_fd = socket(AF_UNIX, SOCK_DGRAM, 0)) < 0)
{
LOG_SYS(0,("ERROR: Can't create unix domain socket for IPC pipe...\n"));
exit(EXIT_ERROR_FATAL);
}
bzero((char*)&ip_serv_addr, sizeof(ip_serv_addr));
ip_serv_addr.sun_family = AF_UNIX;
snprintf(ip_serv_addr.sun_path, sizeof(ip_serv_addr.sun_path)-1,
"%s/pipe_inc.%u", lp_var_path(), lp_udp_port());
DEBUG(90, ("Binding pipe socket to: %s\n", ip_serv_addr.sun_path));
ip_saddrlen = sizeof(ip_serv_addr.sun_family) + strlen(ip_serv_addr.sun_path)+1;
if (unlink(ip_serv_addr.sun_path) == 0)
{
LOG_SYS(0, ("Init: Unix socket (incoming) exist: unclean shutdown?...\n"));
}
if (bind(incoming_pipe_fd, (struct sockaddr *)&ip_serv_addr, ip_saddrlen) < 0)
{
LOG_SYS(0, ("ERROR: Can't bind pipe socket to special file...\n"));
exit(EXIT_ERROR_FATAL);
}
chmod(ip_serv_addr.sun_path, 0600);
}
####################################################################################
I included information about my system.
This code works fine on FreeBSD, Linux, Solaris, Irix.
