You are contradicting yourself. You want a stream that doesn't send classes, but then describe a data structure you want to stream. The fact that you want a header implies you want to send a message, not a stream. You do not stream messages. You send messages _or_ you stream data. > An example piece of data could be a timestamp which is a double value.

Unless you have a continuous stream of timestamps, in which case you stream doubles. But what would be the point of streaming timestamps? > I can do all this at a low level but was wondering if I should really be > using the stream classes to do this?

If so which stream > class to use? A stringstream is an iostream designed for text. It is probably inappropriate for use. You can always derive your own custom stream from one of the iostream classes, but again, I don't think you are looking for streams here. It sounds like you want to send messages, ... I assume messages of the network variety, probably UDP. -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated. First time posters: Do this! ] |
