Hello all, I'm having problem declaring bit as global in header file to avoid including extern bit xxx in other files. I've followed Keil instruction from this link: http://www.keil.com/support/docs/1868.htm
So far all the variables are good, and I don't have to use extern type variable xxx any more. For bit I try to do this:
_DECL bit xxx _INIT(x);
but it doesn't work. Is there any way to get it through? Would it be good to use struct in this case? If so, how should I do this? Any inputs would be greatly appreciated.
Best Regards, T.L
But you are still at risk from typos like
#ifdef "the module that has the definitions" signed blah #else extern unsigned blah #endif
And, because the preprocessor trick ensures that the compiler can never see both, then you are assured that it can never warn you!
