I'm wondering if anyone knows if there is an equivalent capability on mac os to query the number of bytes that a process reads and writes to disk. On Linux you can look in /proc/self/io and find the information there. The documentation in Linux gives the definition for these number as noted below. I'm wondering if this information can be obtained on the mac. thanks, --Corey //----------------------Getting two numbers out of this file // I/O counter: chars read //The number of bytes which this task has caused to be read from storage.

Similar caveats apply here as with rchar. This email sent to site_archiver@lists.apple.com
