It is wired that return value is "ENOENT - No such file" while the file exist.Except opensuse11.3,the return value of other distributions are all "EINVAL - Invalid argument." So i just want to confirm there is no potential issue and just a feature/known issue of Opensuse11.3. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
