It is a different thing. The question is, for example, how to add a new 
menu entry into current menu. Suppose this command:

entry "foo" {
}

The command "entry" should be an ordinary command. I don't want to make 
it special like "title" in GRUB Legacy. Then, this command must be able 
to access a menu variable. So, one way is to define the function like 
this:

grub_err_t 
grub_cmd_entry (struct grub_arg_list *state, int argc, char **args, 
grub_context_t context)
{
  grub_menu_add_entry (context->menu, ...);
  ...
}

Another way is:

grub_err_t 
grub_cmd_entry (struct grub_arg_list *state, int argc, char **args)
{
  grub_context_t context = grub_get_context ();

  grub_menu_add_entry (context->menu, ...);
  ...
}
