I can't even figure out how you could impose that requirement, even if you deliberately tried to do so. Except perhaps have std::cout declared in one, and its operators in the other. --- news://freenews.netfront.net/ - complaints: news@netfront.net --- |

As far as I can tell, yes. (At least in n3797). From 17.6.5.2p1 A C++ header may include other C++ headers. A C++ header shall provide the declarations and definitions that appear in its synopsis. A C++ header shown in its synopsis as including other C++ headers shall provide the declarations and definitions that appear in the synopsis of those other headers. The synopsis for iostream includes ostream. (See 27.4.1). Martin Shobe |
