    external classes

    can i do external class definitions with the extern keyword? i don't want to have a seperate copy of the class definitions... [or seperate them from the class function declarations and include them parallel per each obj code / cpp]...

    something like...

    Code:
    extern class MY_CLASS;
    extern MY_CLASS class_instance;
    also, if MY_CLASS is nested with many subclasses, do i have to extern those as well [provided that i _could_] correct? thanks quite so...

    Why not? I'm pretty sure you can.
    What will people say if they hear that I'm a Jesus freak?
    What will people do if they find that it's true?
    I don't really care if they label me a Jesus freak, there is no disguising the truth!

    Code:
    q.cpp:16: `extern' can only be specified for objects and functions
    error... so no? DJGPP is my compiler... and if there isn't a standard for this, i'll be damned... any alternative that does require seperation or duplication of the class declaration inclusion?
