You could call an error routine with your string as an argument,
or
or &Error("Could not pen the file a.txt" ;
Then in your Error sub you do what ever you want to do with that
error. I have used this and considered expanding it to include
error codes in warning/fatal ranges etc but have not yet felt the
need.
This is what mine does (The $log->msg liones are from Log::Simple.):
sub Error {
local ($errormessage) = @_;
if (defined $log) {
$log->msg(1,$errormessage);
}
print "\n\nERROR:\t" . $errormessage . "\n\n" ;
# rollback DB if it was connected
if (defined $dbh ) {
$rc = $dbh->rollback ;
}
if (defined $log) {
$log->msg(1,"Rollback:\t",$rc,"\n");
}
print "\nCalling cleanup to close connections and rollback
etc...\n" ;
Cleanup();
if ($SendEmailNotification) {
$subjmodifier= " - ERROR" ;
$EmailBody = $errormessage;
PrepEmailNotification($subjmodifier,$EmailBody,@FileList);
} else {
if (defined $log) {
$log->msg(1,"Email notification
disabled\n");
}
}
Perhaps a more experienced Perl Monger might comment on that approach
in general ?
