I trying to find a solution for a problem that involves "long" filenames
under windows 2k/xp. This script:
<code>
use strict;
use Win32;
$|++;
testfiles(250,300);
sub testfiles {
my($lower,$upper)[EMAIL PROTECTED];
for my $i ($lower..$upper) {
print "checking filename length of $i\n";
my $filename="x" x $i;
open(OUT,">$filename") || die "open for write - $!";
binmode(OUT);
print OUT "x" x $i;
close(OUT);
my $copy=$filename.qq{.1};
unlink($copy);
Win32::CopyFile($filename,$copy,1);
if(! -e $copy) {
print "Copy failed - $^E\n";
} else {
unlink($copy);
}
unlink($filename);
}
}
</code>
will produce the following output, when run in c:\
...
checking filename length of 251
checking filename length of 252
checking filename length of 253
checking filename length of 254
Copy failed - The filename, directory name, or volume label syntax is
incorrect
checking filename length of 255
Copy failed - The system cannot find the path specified
checking filename length of 256
open for write - Invalid argument at \\santafe\c\tmp\perl\longfile\test.pl
line 13.
We obviously deal with a filename length limitation on perl-Windows. I
checked the man-pages and found mention of the -C command line flag and the
${^WIDE_SYSTEM_CALLS} variable in 'perldoc perlvar'. Both don't seem to make
any difference on my system and I was wondering if anybody happens to know
how I can convince perl on Win2K/WinXP to consume filenames with more than
256 characters.
perl -v is v5.6.1 build 635.
Do I have to upgrade to 5.8 and retry "-C"/WIDE_SYSTEM_CALLS?
Thanks in advance
Tobias
