NAME

CGI::MxScreen::Error - Error return codes for action callbacks

SYNOPSIS

 use CGI::MxScreen::Error;

 sub action {                # action callback
     ...
         return CGI_MX_ABORT;    # for instance
 }

DESCRIPTION

This module exports the return codes to use in action callbacks:

CGI_MX_OK

Signals everything went fine.

CGI_MX_ABORT

An error was detected, and the action callback chain should be immediately exited. No further callbacks will be invoked.

CGI_MX_ERROR

An error was detected, but further action callbacks may still execute. The error condition is remembered and will be raised at the end of the callback chain.
