According to the man page of sysctl() KERN_FILE will return a file structure which is not at all documented ( not confirm about the structure to use ), there is no file structure exposed on Mac OS X (apart from extern_file and filedesc), I am not sure which structure to use ? is it possible to get per process file information using KERN_FILE? Is it the correct approach or there is any other way to get the same ? OS version is 10.4.7 Thanks in advance! This email sent to tlambert@apple.com This email sent to site_archiver@lists.apple.com
