Function : meta_namespace()

This function just return an almost unique namespace for module's metabox which are generated by GUI V1 Class.

The prefix is created using module namespace. That's why this function is only used by modules.

Here is how it works

PHP

<?php
// we assume module namespace is "custom"
$namespace	=	meta_namespace( 'header' );
// $namespace has now = "custom.tendoo.meta.org/header"
// or
$namespace 	=	meta_namespace( array( 'header' , 'top' ) );
// returns "custom.tendoo.meta.org/header/top"
