 * WordPress uses the weblog_ping function in the functions.php file to send a ping
   to an aggregator. The aggregator receives the ping which contains the URL to 
   the blog and its title. It then turns around and issues a pingback or trackback
   and fetches the permalink to the current post as well as its title.
 * Which WordPress function does it invoke to fetch these two parameters?

 * invoke which two parameters? The permalink and post title? These are passed via
   HTTP POST when the publish (or edit) button is pressed in the edit screen.

 * Thanx! Where can I find a description of the datastructure used? I am picking
   up the two parms that come via the weblog_ping function, or at least I assume
   that it comes from there. But I am not seeing the other two parms, i.e. permalink
   and Post Title.

 * Take a look through `/wp-admin/post.php`. This should show you how pingbacks 
   and trackbacks are triggered.

 * weblog_ping uses the data from the options table, which is set under your options
   tab.

 * Right. My confusion stems from the fact that weblog_ping implements the [http://www.xmlrpc.com/weblogsCom](http://www.xmlrpc.com/weblogsCom)
   XML-RPC protocol. I understand how it works, and weblog_ping sends two parms,
   which I pick up correctly. But it does not send the permalink and post title.
   So are they sent separately? The reply above seems to say that they are sent 
   separately in an HTTP Post.
