Add a top-level menu page in the ‘objects’ section.

This function takes a capability which will be used to determine whether
or not a page is included in the menu.

The function which is hooked in to handle the output of the page must check
that the user has the required capability as well.

function add_object_page( $page_title, $menu_title, $capability, $menu_slug, $callback = '', $icon_url = '') {
	_deprecated_function( __FUNCTION__, '4.5.0', 'add_menu_page()' );

	global $_wp_last_object_menu;

	$_wp_last_object_menu++;

	return add_menu_page($page_title, $menu_title, $capability, $menu_slug, $callback, $icon_url, $_wp_last_object_menu);
}
