`$function` is a string and is the name of the function which will be executed when the hook is called.
### Arguments
-Your hook callback functions will be called with at least one and possibly two arguments
+Your hook callback functions will be called with at most one argument
- function <addon>_<hookname>(App $a, &$b) {
+ function <addon>_<hookname>(&$b) {
}
If you wish to make changes to the calling data, you must declare them as reference variables (with `&`) during function declaration.
-#### $a
-$a is the Friendica `App` class.
-It contains a wealth of information about the current state of Friendica:
-
-* which module has been called,
-* configuration information,
-* the page contents at the point the hook was invoked,
-* profile and user information, etc.
-
-It is recommeded you call this `$a` to match its usage elsewhere.
-
#### $b
$b can be called anything you like.
This is information specific to the hook currently being processed, and generally contains information that is being immediately processed or acted on that you can use, display, or alter.
Your addon can provide user-specific settings via the `addon_settings` PHP hook, but it can also provide node-wide settings in the administration page of your addon.
-Simply declare a `<addon>_addon_admin(App $a)` function to display the form and a `<addon>_addon_admin_post(App $a)` function to process the data from the form.
+Simply declare a `<addon>_addon_admin()` function to display the form and a `<addon>_addon_admin_post()` function to process the data from the form.0

}
-function <addon>_head(App $a)
+function <addon>_head()
{
\Friendica\DI::page()->registerStylesheet(__DIR__ . '/relative/path/to/addon/stylesheet.css');
}

-function <addon>_footer(App $a)
+function <addon>_footer()
{
\Friendica\DI::page()->registerFooterScript(__DIR__ . '/relative/path/to/addon/script.js');
}
DI::args()->get(2); // = 'arg2'
```
-To display a module page, you need to declare the function `<addon>_content(App $a)`, which defines and returns the page body content.
-They may also contain `<addon>_post(
App $a)` which is called before the `<addon>_content` function and typically handles the results of POST forms.
-You may also have `<addon>_init(
App $a)` which is called before `<addon>_content` and should include common logic to your module.
