Is unlink() supposed to provide an error message on failure?

[David Christensen]

beginners:

Is unlink() supposed to provide an error message on failure?  The
documentation does not say so:

    http://www.perl.com/doc/manual/html/pod/perlfunc/unlink.html


Testing indicate that unlink() sets $! on failure:

    2009-11-18 11:42:40 dpchr...@vmlamp ~
    $ cat foo
    #! /usr/bin/perl
    print '$! = ', $!, "\n";
    unlink 'no/such/file';
    print '$! = ', $!, "\n";

    2009-11-18 11:42:49 dpchr...@vmlamp ~
    $ perl foo
    $! =
    $! = No such file or directory


TIA,

David
