Or is it a problem with our shmget()? http://pubs.opengroup.org/onlinepubs/9699919799/functions/shmget.html http://man7.org/linux/man-pages/man2/shmget.2.html Perhaps we should be just returning -1 with an errno (ENOSYS?) instead of raise(SIGSYS)? -- Yaakov -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
