rss_enclosure()
Display the rss enclosure for the current post.
Description Description
Uses the global $post to check whether the post requires a password and if the user has the password for the post. If not then it will return before displaying.
Also uses the function get_post_custom() to get the post’s ‘enclosure’ metadata field and parses the value to display the enclosure(s). The enclosure(s) consist of enclosure HTML tag(s) with a URI and other attributes.
