I'm using MacOSX::File::Info to get the Type and Creator codes for files.
In trying to print these (e.g., via NSLog and in an NSTextView), I ran
into a peculiar symptom: not only did the code not print, any following
information on the line also disappeared.
After a bit of research, I confirmed that the creator and type methods
were returning a string of four nulls when no real code was available.
This is probably normal behavior in Macland, but it's distinctly non-
Perlish. Sigh.
Anyway, my workaround was to generate my own string of four nulls,
which I could use to check return values:
my $null = "\000\000\000\000";
$tmp = $finfo->creator;
$tmp = '' if ($tmp eq $null);
row(' Creator', "'$tmp'");
$tmp = $finfo->type;
$tmp = '' if ($tmp eq $null);
row(' Type', "'$tmp'");
-r
