I guess it would have helped to include the area where I have the use File::stat... sigh. I did not want to post all 200+ lines of my script. In the code below I have the use statement from the original script as well as a copy of the variable I am passing in and the call itself. I hard coded the dir name until I get this piece working. I still get the "The dirfd function is unimplemented at DirStat.pl line 10."

#use File::stat;

my $_checkDir = "c:\\drivers";
&DirCheck($_checkDir);

sub DirCheck {
    my $_dir = $_[0];
    opendir(my $dh, $_dir)
        or die "Can't open directory $_dir: $!\n";
    my $_dirStat = stat($dh)
        or die "Can't stat directory $_dir: $!\n";
    closedir($dh);

    print "Directory: $_dir\n";
    for my $field (qw(
         dev ino mode nlink uid gid rdev size
     atime mtime ctime blksize blocks
    )) {
        print "$field: ", $_dirStat->$field(), "\n";
    }

    my $_mtime = $_dirStat->mtime;
    print "Last Modified Time for $_dir: $_mtime\n";
}
