Hi:

     Sorry posting here. I'm not member of the developers group but I have
a question that maybe someone from this list can help me !

The problem is that I'm tring to port an irc gateway to WWW, written by
Zhong Yang
in C. I'm stuck in the following:


this is from /include/sys/socket.h
struct sockaddr {
	u_char	sa_len;			/* total length */
	u_char	sa_family;		/* address family */
	char	sa_data[14];		/* actually longer; address value */

this is from /include/netinet/in.h
struct sockaddr_in {
	u_char	sin_len;
	u_char	sin_family;
	u_short	sin_port;
	struct	in_addr sin_addr;
	char	sin_zero[8];


And here, the problem. That's actually part of the code of the gateway:


struct sockaddr_in SocketInetAddr;
       ^^^^^^^^^^^

SocketInetAddr.sin_port = htons(Port);
	SocketDescriptor = socket(AF_INET, SOCK_STREAM, 6);
	if (SocketDescriptor < 0)
		{
		perror("socket");
		return (-1);
		}
	if (connect(SocketDescriptor, ( char *) &SocketInetAddr,
sizeof(SocketInetAddr)) < 0)
                                      ^^^^^^^^^^^^^^^^^^^^^^^^^
		RETURN_SUCCESS=1;
	else
		RETURN_SUCCESS=0;

The above call to CONNECT reports an error because the connect function
expects, in the second field,
the use of sockaddr. But in the program, the call is for sockaddr_in. I
don't know if in AIX or hpux
this structures are the same, but I know that it works there ! Anyone has an
idea how can I change this
piece of code to put it to work in FreeBSD ?

Thanks a lot!  Sorry for the off_topic question!

Regards,
Helio.
