dir.seek( integer ) → dir

Seeks to a particular location in dir. integer must be a value returned by Dir#tell.

d = Dir.new("testdir")   #=> #<dir:0x401b3c40>
d.read                   #=> "."
i = d.tell               #=> 12
d.read                   #=> ".."
d.seek(i)                #=> #<dir:0x401b3c40>
d.read                   #=> ".."</dir:0x401b3c40></dir:0x401b3c40>
