Subject: pluginlib: Update smart_ptr class.
X-Git-Tag: Release-11.3.2~564
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cc20075962bc366383c63820564c72d469fdb301;p=thirdparty%2Fbacula.git

pluginlib: Update smart_ptr class.

Now you can create an empty smart_ptr class with default ctor
and assign a new ptr to already defined object and handle it smartly.
