This struct template implements the enable_if meta-function defined in the C++11 standard [meta.trans.ptr]. This struct template provides a typedef type that is an alias to the (template parameter) t_TYPE if the (template parameter) t_COND is true; otherwise, type is not provided. If t_TYPE is not specified, it is set to void. Note that this generic default template provides type for when t_COND is true; a template specialization is provided (below) that omits type for when t_COND is false.
