Hi all,
I have compiled a C application (japach: http://www.jikos.cz/jikos/japach/) under cygwin on Windows NT. It
works fine on all versions of win32. When I ran it on Windows x64, it
hangs on the following line:
strncpy(buffer2 , client.host_nam e, MAXLINE - strlen(buffer2) );
The problem is client.host_nam e, which is a string. This line is
reached after a few nested calls to different functions. In main,
where client.host_nam e is set, I could output it just fine. When it
gets to this function, it just hangs there.
Shouldn't this work on Windows x64? Winx64 has WOW that allows 32-bit
applications to be run. Is there something I'm not aware of?
Thanks.
Patrick

What are the safer versions of gethostbyaddr and inet_ntoa?
The <OT></OTtags above meant that the advice is off topic and you
should ask for further information else where. If this is the first time
you have come across this you can be forgiven. However, please ask about
those functions and alternative on a group where they are topical,
comp.unix.progr ammer springs to mind as one possibility, but make sure
you check their archives and FAQ to find out if the question has already
been asked and answered and, indeed, if it is topical there.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
