You can't access more than 2GB (or 3GB with the appropriate kernel flag) from any 32 bit Windows process. Since Cygwin's shared memory capabilities are restricted to what the operating system allows, Cygwin won't change that for you. When running Cygwin on Windows 64, it's still a 32 bit DLL, only linkable with 32 bit applications so the usual 32 bit restrictions still apply. Just as a friendly reminder, since you're talking about using Cygwin in an apparently proprietary project, I'd like to point you to the Cygwin licensing terms: http://cygwin.com/licensing.html Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Co-Project Leader mailto:[EMAIL PROTECTED] Red Hat, Inc. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
