DECLARE_SERIAL和IMPLEMENT_SERIAL宏的底層實現有些標記看不懂

#define DECLARE_SERIAL(class_name) \

_DECLARE_DYNCREATE(class_name) \

AFX_API friend CArchive& AFXAPI operator>>(CArchive& ar, class_name* &pOb);

實際上的意思是DECLARE_SERIAL(class_name)定義成下面兩行 _DECLARE_DYNCREATE(class_name)

AFX_API friend CArchive& AFXAPI operator>>(CArchive& ar, class_name* &pOb);
