timeout when reading bad data

rray has asked for the wisdom of the Perl Monks concerning the following question:

I have worked in UNIX for a number of years but I have about 1 week of experience with Windows. We receive dvd's of images. I need to open the images and check some of their tags to determine if we should accept or reject the batch. I use my @imgs = Imager->read_multi(file=>$tiff, type=>'tiff') or die "read_multi failed: $!\n"; This works fine until I get a bad dvd. This will hang for 3 to 15 minutes before giving up. But, Imager->read_multi does not fail. If I copy the file to the hard drive after several minutes I get a partial file. Using Windows XP and ActivePerl 5.8 Since alarm() doesn't work what are my options?

alarm on win32 or you might be able to run a separate timer thread break thread with system(...) call. There are many ways to use a thread as a timer. I don't do windows. I'm not really a human, but I play one on earth Remember How Lucky You Are	[reply]
