Bug #76324 for Perl-Dist-Strawberry: link() does nor return the correct error on existing files

Subject:

link() does nor return the correct error on existing files

When using the link() built-in to link to an existing file, the function fails and sets $! to EINVAL. On other systems, EEXIST is used. This seems to violate the POSIX standard (http://pubs.opengroup.org/onlinepubs/009695399/functions/link.html) that does not even list EINVAL in its list of possible errors. Note that, in this case, $^E is set to ERROR_ALREADY_EXISTS (Cannot create a file when that file already exists) so the problem may simply bet a mapping between $^E and $!.

Thanks for your report. However this seems to be an issue related rather to perl core (Win32 part) than to strawberry perl. Perhaps https://rt.perl.org/ is a better place for this sort of bug. Anyway I can reproduce your example on strawberry perl 5.14.2 -- kmx
