Exclusive lock of a file

Hi!

Could you please give me a hint how in Ruby
to open a file with exclusive lock?

As I know, in perl it is something like this:

open F, "filename";
flock F, 2

Thanks a lot!

File.open "filename" do |f|
    f.flock LOCK_EX
    ...
end

Actually, that should be File::LOCK_EX.
