This function aborts processing of the ADP file and sends any pending output (from ns_adp_puts or static HTML) up to the point where it was called to the browser. Nothing is output or executed after it is called.
The return_value, if specified, becomes the return value of the ADP.
Note that this function returns only one level up the call stack. To return all the way up the call stack, use ns_adp_break.
