I've attached the smallest testcase I can think of. What I'd like to=20 know is why this doesn't work, while gethostbyname() on localhost works=20 like a charm? Is this a bug in my brain, in W32/9x or in Cygwin=20 (probably the second, possibly the first) Ronald NB: Work won't allow to spend time on Cygwin - so I won't be able to=20 fix anything as I won't be able to get the release form signed.=20 Should be possible in three months though: work won't exist anymore=20 :) ------=_NextPart_000_002B_01C24DED.54BDADA0 Content-Type: application/octet-stream; name="Makefile" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="Makefile" all : test test : test.cc gcc -Wall -Werror -g -o test test.cc clean : rm -f *.exe *.o *~ test ------=_NextPart_000_002B_01C24DED.54BDADA0 Content-Type: application/octet-stream; name="test.cc" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="test.cc" #include #include #include #include int main(void) { unsigned long int i_IP; struct hostent *host_info; i_IP = inet_addr("127.0.0.1"); host_info = gethostbyaddr((char *)&i_IP, sizeof(i_IP), AF_INET); if (host_info == NULL) perror("Failed!"); } // main() ------=_NextPart_000_002B_01C24DED.54BDADA0 Content-Type: text/plain; charset=us-ascii -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/ ------=_NextPart_000_002B_01C24DED.54BDADA0--
