=head1 NAME
Lchown - use the lchown(2) system call from Perl
=head1 SYNOPSIS
use Lchown;
lchown $uid, $gid, 'foo' or die "lchown: $!";
my $count = lchown $uid, $gid, @filenames;
# or
use Lchown qw(lchown LCHOWN_AVAILABLE);
warn "this system lacks the lchown system call\n" unless LCHOWN_AVAILABLE;
...
# or
use Lchown ();
warn "this won't work\n" unless Lchown::LCHOWN_AVAILABLE;
Lchown::lchown $uid, $gid, 'foo' or die "lchown: $!";
=head1 DESCRIPTION
Provides a perl interface to the C<lchown()> system call, on platforms that
support it.
=head1 DEFAULT EXPORTS
The following symbols are exported be default:
=over
=item lchown (LIST)
Like the C<chown> builtin, but using the C<lchown()> system call so that
symlinks will not be followed. Returns the number of files successfully
changed.
On systems without the C<lchown()> system call, C<lchown> always returns
C<undef> and sets C<errno> to C<ENOSYS> (Function not implemented).
=back
=head1 ADDITIONAL EXPORTS
The following symbols are available for export but are not exported by
default:
=over
=item LCHOWN_AVAILABLE ()
Returns true on platforms with the C<lchown()> system call, and false on
platforms without.
=back
