   Another typical usage is to register a new setting for use by a plugin:

   function myplugin_settings() {
       register_setting( 'myplugin', 'myplugin_setting_1', 'intval' );
       register_setting( 'myplugin', 'myplugin_setting_2', 'intval' );
   }
   add_action( 'admin_init', 'myplugin_settings' );

   This example works similarly to the first example, but it will automatically redirect users lacking the specified capability to the homepage.

   /**
    * Restrict access to the administration screens.
    *
    * Only administrators will be allowed to access the admin screens,
    * all other users will be automatically redirected to the front of
    * the site instead.
    *
    * We do allow access for Ajax requests though, since these may be
    * initiated from the front end of the site by non-admin users.
    */
   function restrict_admin_with_redirect() {
   
   	if ( ! current_user_can( 'manage_options' ) && ( ! wp_doing_ajax() ) ) {
   		wp_safe_redirect( site_url() ); 
   		exit;
   	}
   }
   
   add_action( 'admin_init', 'restrict_admin_with_redirect', 1 );

   Example migrated from Codex:

   In this example, we block access to the admin panel for users that do not have the Administrator Role.

   /**
    * Restrict access to the administration screens.
    *
    * Only administrators will be allowed to access the admin screens,
    * all other users will be shown a message instead.
    *
    * We do allow access for Ajax requests though, since these may be
    * initiated from the front end of the site by non-admin users.
    */
   function restrict_admin() {
   
   	if ( ! current_user_can( 'manage_options' ) && ( ! wp_doing_ajax() ) ) {
   		wp_die( __( 'You are not allowed to access this part of the site' ) );
   	}
   }
   add_action( 'admin_init', 'restrict_admin', 1 );

   /**
    * Fire on the initialization of the admin screen or scripts.
    */
   function the_dramatist_fire_on_admin_screen_initialization() {
       // Do stuff. Say we will echo "Hello World".
       echo 'Hello World';
   }
   add_action( 'admin_init', 'the_dramatist_fire_on_admin_screen_initialization' );

   The above piece of code will only echo “Hello World” if the user is in admin screen.
