   // It doesn't take any parameters. On success it
   // returns a two-element array, the first of which
   // has the value FALSE, and the second is an array
   // of values. On failure (if the session variables
   // don't exists, for example), it returns a single
   // element array with the value FALSE. An easy way
   // to read the return values is with a list()
   // statement, like this:
   //
   //    $result = PIPHP_OpenSession();
   //    list($h, $p, $n, $e) = $result[1];
