Reserved identifiers in general are not only for future use of the standard, but also for internal use of implementations and for extensions. The single-under bar rule is to give the programmer some part of the _... namespace which is otherwise reserved for the implementation. I.e. for use in macros, variables, or struct members. The intention is for use in hidden names in some API. |
