-Modules can also define function hooks. Other modules can then add
-functions to these hooks to make the first module call these functions
-instead of the default.
-
-Again, an array is used to define hooks:
-
-  static struct hookdef foohooks[] = {
-    HOOKDEF("foo", foofunc, 0),
-  };
-
-The first argument of the macro is the name of the hook. This name
-is used whenever the hook is used. The second argument is the default
-function for the hook or NULL if no default function exists. The
-last argument is used to define flags for the hook. Currently only one
-such flag is defined: `HOOKF_ALL'. If this flag is given and more than
-one function was added to the hook, all functions will be called
-(including the default function). Otherwise only the last function
-added will be called.
-
-The functions that can be used as default functions or that can be
-added to a hook have to be defined like:
-
-  /**/
-  static int
-  foofunc(Hookdef h, void *data)
-  {
-    ...
-  }
-
-The first argument is a pointer to the struct defining the hook. The
-second argument is an arbitrary pointer that is given to the function
-used to invoke hooks (see below).
-
-The functions to register and de-register hooks look like those for
-the other things that can be defined by modules:
-
-  /**/
-  int
-  boot_foo(Module m)
-  {
-    int ret;
-
-    ret = addhookdefs(m->nam, foohooks, sizeof(foohooks)/sizeof(*foohooks))
-    ...
-  }
-  ...
-  /**/
-  int
-  cleanup_foo(Module m)
-  {
-    deletehookdefs(m->nam, foohooks, sizeof(foohooks)/sizeof(*foohooks));
-    ...
-  }
-
-Modules that define hooks can invoke the function(s) registered for
-them by calling the function `runhook(name, data)'. The first argument 
-is the name of the hook and the second one is the pointer given to the 
-hook functions as their second argument. Hooks that have the `HOOKF_ALL' 
-flag call all function defined for them until one returns non-zero.
-The return value of `runhook()' is the return value of the last hook
-function called or zero if none was called.
-
-To add a function to a hook, the function `addhookfunc(name, func)' is 
-called with the name of the hook and a hook function as arguments.
-Deleting them is done by calling `deletehookfunc(name, func)' with the 
-same arguments as for the corresponding call to `addhookfunc()'.
-
-Alternative forms of the last three function are provided for hooks
-that are changed or called very often. These functions,
-`runhookdef(def, data)', `addhookdeffunc(def, func)', and
-`deletehookdeffunc(def, func)' get a pointer to the `hookdef'
-structure defining the hook instead of the name and otherwise behave
-like their counterparts.

 Finally, modules can define wrapper functions. These functions are
 called whenever a shell function is to be executed.
