20 CGI::Session::ErrorHandler provides set_error() and errstr() methods
21 for setting and accessing error messages from within CGI::Session's
22 components. This method should be used by driver developers for
23 providing CGI::Session-standard error handling routines for their code
24
25 METHODS
26 set_error($message)
27 Implicitly defines $pkg_name::errstr and sets its value to
28 $message. Return value is always undef.
29
30 errstr()
31 Returns whatever value was set by the most recent call to
32 set_error(). If no message as has been set yet, the empty string is
33 returned so the message can still concatenate without a warning.
