Error Handling for Knewsticker Pre commands
|
|
|
|
Error handling might not be a prerequisite for writing Knewsticker scripts,
|
|
yet it would be nice if you tried to introduce some comprehensive error
|
|
handling in your scripts. Knewsticker is a graphical application and as such
|
|
the user is not able to read any error output your program might produce.
|
|
Knewsticker knows a variety of error codes and each is handled in a
|
|
different way. You may look those codes up in the table provided.
|
|
|
|
Please make sure to return those error codes properly for the development
|
|
language you are trying to use. If you are trying to use Perl, please make
|
|
sure you understand an have read the top most part of the error handling
|
|
document. It will explain to you, how it is fairly easy to catch errors and
|
|
report them back to Knewsticker.
|
|
|
|
If you are still unsure how to do it on a system level, simply implement
|
|
your own error handling and make sure, that your return codes match the
|
|
event(s) described in the error handling document you will find in CVS as
|
|
well.
