/** \defgroup pw_resource Resource * * \brief Client owned objects * * Resources represent objects owned by a \ref pw_impl_client. They are * the result of binding to a global resource or by calling API that * creates client owned objects. * * The client usually has a proxy object associated with the resource * that it can use to communicate with the resource. See \ref page_proxy. * * Resources are destroyed when the client or the bound object is * destroyed. *
