Re: gethostbyname on local host returns 127.0.0.1 for address

On windows gethostbyname for the local host returns the addresses of the available network interfaces. On wine and unix, it only returns the localhost 127.0.0.1.
Any ideas on how to get the windows behavior?
I assume you're referring to gethostname (as in your sample code), not gethostbyname (as in your email). Well, I guess you'd have to modify winsock/socket.c's WS_gethostname function, maybe to call GetAdaptersInfo or some such. That'll get you the addresses, anyway. If you want a name other than localhost you may want to call GetNetworkParams too. --Juan __________________________________ Do you Yahoo!? Yahoo!

It's gethostbyname that has the problem. gethostname is just used to find the name of the machine that the program is running on and is what is passed to gethostbyname. gethostbyname should return a host structure which contains an array of addresses associated with the host. On windows, the addresses are the addresses of the network interfaces. On wine and unix, the address returned is 127.0.0.1 which is localhost, not the actual interface address.

Oops, you're right, I didn't read your code that closely. What I said earlier is still appropriate though: you can call something in iphlpapi, like GetAdaptersInfo, or perhaps GetIpAddrTable. You could also use WSAIoctl. Take a look at dlls/winsock/socket.c; you'd want to modify WS_gethostbyname, and it already calls GetAdaptersInfo to implement WSAIoctl. Do you have an app that depends on this, or are you just trying to get the network interface addresses? --Juan __________________________________ Do you Yahoo!? Yahoo!
