关键还是要看到,要给在父类的函数指针付值,还有给初始化函数加返回值总觉得不是很好。所以就改了下
不过把super暴露在外面了
#include "subrealize.h"CSubRealize subrealize;CSub* pSub;short id=10;void main()...{ pSub=CSubRealize_Initial(&subrealize); #if 0 (pSub->Get)(&subrealize,id); (pSub->Set)(&subrealize,id); (pSub->Clear)(&subrealize,id);#endif subrealize.super.Get(&subrealize,id); subrealize.super.Set(&subrealize,id); subrealize.super.Clear(&subrealize,id);}
