perlio::via::symlink

symlink(3)						User Contributed Perl Documentation						symlink(3)

NAME

       PerlIO::via::symlink - PerlIO layers for create symlinks

SYNOPSIS

	open $fh, '>:via(symlink)', $fname;
	print $fh "link foobar";
	close $fh;

DESCRIPTION

       The PerlIO layer "symlink" allows you to create a symbolic link by writing to the file handle.

       You need to write C"link $name" to the file handle. If the format does not match, "close" will fail with EINVAL.
