wp_meta()

Theme container function for the ‘wp_meta’ action.

The ‘wp_meta’ action can have several purposes, depending on how you use it, but one purpose might have been to allow for theme switching.

By default, wp meta() is called immediately after wp_loginout() by sidebar.php and the Meta widget, allowing functions to add new list items to the widget.
As the get_sidebar( $name ); function has the do_action( 'get_sidebar', $name ); on top before it loads the sidebar file, this hook should be used to load stuff before the sidebar and wp_meta(); should be called at the end of the sidebar template to allow adding callbacks after the sidebar.

function wp_meta() {
	/**
	 * Fires before displaying echoed content in the sidebar.
	 *
	 * @since 1.5.0
	 */
	do_action( 'wp_meta' );
}
