Could someone give a small example of a use of double indirection or
just explain when and where it's used. I've been using C for about
6 months and have yet to use this feature. More specifically I've
seen this:

  char **argv.

Now I've used char *argv[] many times but can't see how the two relate.

Thanks in advance.
