Alright, sorry about that.

I'll give you a more elaborate code soon, but about thre results, what happens 
is that:

www.google.com:80 --> The function returns a value different from zero, errno 
returns successful and the IP addresses returned (both local and remote) are 
correct.

I've tried this also with forums.gentoo.org:80, sf.net:80, 
upload.sf.net:21, ...

As soon as I find the piece of code I used, I'll post it :)

Oops. I saw your comment.
After modifying my code a bit more (with the source I provided you) I got this:

ioannis@petekan gso $ ./gso www.google.com 80
gethostname         OK
socket              OK
connect             OK
getsockname         Success
getsockname: 10.30.102.123:56575
getpeername         Success
getpeername: 66.102.9.104:80
EXITING

Should have done that from the begining.

In the code:

	if(getpeername(SocketDesc,(sockaddr *)&gsoSA,&gsoSL))
	{
		cout << strerror(errno) << endl;
		return -4;
	}

If the returned value is zero, the statement is false, so it won't exit. I 
still don't understand why it failed in the previous code. Anyway. Now I have 
my app up and running.

Thanks for the time.

kernel.org refused to solve this bug, arguing it's a glibc issue:

------- Additional Comment #3 From Hideaki YOSHIFUJI 2004-09-21 00:47 ------- 
Kernel is not responsible to errno, but glibc is;
it should setup errno appropriately returned from syscall.


------- Additional Comment #4 From Hideaki YOSHIFUJI 2004-09-21 00:48 ------- 
Please report this to the appropriate community (glibc).


See bug: http://bugme.osdl.org/show_bug.cgi?id=3387 for additional info.

getsockname in glibc is nothing but a syscall wrapper.  If you have a problem,
this is a problem in the kernel.  Report the bug appropriately.

I certainly can't reproduce this, neither on IA-32 nor x86-64.
Please write what exact arguments you call the test with, run it under
strace and show its output and what kernel you're using.

This behaviour described for getsockname also happens for the getpeername()
function, which returns a value different from zero when successful.

This is a sample source code that reproduces the bug (requires the header file)

I add a sample source code that reproduces the bug:

gso.cpp and gso.h
