Hello, i have to write a clone of perl's stat using external programs. Basically i use /usr/bin/stat and massage a little the output.

But i had a problem with the 'rdev' return value ('rdev' is the sixth element of the returned list). I just don't know what is his meaning and therefore i couldn't get a way to get it with a external program.

The stat documentation in perlfunc states the following about 'rdev':

'6 rdev the device identifier (special files only)'
I was unable to found nay other reference about this return value.

Any info or pointer about the elusive 'rdev' would be greatly welcome. Thanks!
