of this. Is there some way I should be wrapping calls
to the shared lib in something like an eval BLOCK, so I can croak a
message back to the web page?
perldoc -q exception turned up a result from perlfaq8 just so you know the
tools for exception handling are there. You might be able to catch the
exception
I have a Perl module that calls a function from in a Swig generated
module, which in turn calls a function in a shared library. It's been a
while since I put it all together and made it work, so I'm kind of hazy
on the technical details - and since it mostly works I never need to
look at it.
Dear Perlers,
I am trying to figure out the flow of a try catch block after executing the
'next' statement. In the try statement after illegal division by zero the
program flow reaches catch block and then executes the 'next' statement. After
executing the next statement the control flow has

Hi All,
Can we handle exceptions in PERL programs?
For example - Here if it fails to copy then can I handle the exception
and perform the next steps in my script? I tried removing die but then
it does not complain and I wont be able to come to know if that is
copied or not. (Is there

simplest (?) solution:
copy (C:\\build.xml,D:\\build.xml) or print Cannot copy : $!;
You can also have it do more than one thing:
copy (C:\\build.xml,D:\\build.xml) or (

Or you can have more fun:

print Cannot copy : $!;
Thanks...
My bad... I did not realize to use print instead of just dieing :)
Thanks,

there is a Error.pm in CPAN, which allows you to write code like that
try {
something();
} catch Error with {
code();
}otherwise{
foobar();
};

How do we handle exceptions in perl?
If you want *proper* exception handling (exception objects, try/catch, stack
traces, etc), the don't use:
die $message;
return 0;
eval {}; # except with exception objects

Hello,
I am interfacing an XML file with a database, much like the last example at
http://www.xmltwig.com/xmltwig/tutorial/yapc_twig_s5.html
What I am actually doing is checking if the table already got such a record,
if so - updating it, otherwise inserting it, but this is not relevant.
Either way I can't figure out how to raise an exception in the insert_row
subroutine so that the parsefile() will die as well. Since I am working with
records totalling several gigabytes, I am checking every SQL operation by
evaling them with RaiseError turned on. This doesn't help me much,
, then it would know that it needed to deal
with what ever the errno was...
One part of the problem here is 'getting the exception handling'
into the process so that there are enough 'error message indicators'
to assert what went wrong, and hopefully where. But the b-side of
that would be working out

I'd like to setup customised exception handling, but am unsure
how to impliment it. I started by reading `perldoc -f die` and
went from there, but the explanation of what I want to do is a
bit over my head. So, I'm looking for pointers, code, favoured
modules, and/or more suggested reading

What I hoped to have happen is that if a particular sub returns

What I'm unsure of, is how to get the die_msg/STDERR to pass
