In fact i wasn't using the SHM_RNd flag. In details here is what i do: - get a shared segment of with size= SIZE (SIZE multiple of SHMLBA) - attach the segment without specifying address and storing the result in beginaddress - attach the segment again specifying the address: endposition= beginaddress + SIZE without SHM_RND in the second shmat i've got the error : invalid argument now that i specifie SHM_RND in the flag i have the error: value to large for defined type .... any idea ? thanks bertrand -- 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/
