Re: STDOUT, STDERR sniffer

You reopen each handle to do what you want, for instance in 5.8 you can easily capture to variables,

my ($output, $messages);
{
    open local(*STDOUT), '>', \$output or die $!;
    open local(*STDERR), '>', \$messages or die $!;
    # ...
}
[download]

If you prefer, you can open to disk files instead in any version of perl. To capture to variables in earlier versions of perl, you must use IO::Scalar or similar.

This code causes 2 uninitialized warnings: `Use of uninitialized value in open. Use of uninitialized value in open at ./a.pl line 8.` [download] the two errors are from the two open calls. how can i make the warnings go away ?	[reply] [d/l]
