关于结构数组初始化，这个数组有几个元素？每个被填入了什么值？讨厌的宏！（内详！）
struct _ATL_OBJMAP_ENTRY
{
const CLSID* pclsid;
HRESULT (WINAPI *pfnUpdateRegistry)(BOOL bRegister);
_ATL_CREATORFUNC* pfnGetClassObject;
_ATL_CREATORFUNC* pfnCreateInstance;
IUnknown* pCF;
DWORD dwRegister;
_ATL_DESCRIPTIONFUNC* pfnGetObjectDescription;
_ATL_CATMAPFUNC* pfnGetCategoryMap;
HRESULT WINAPI RevokeClassObject()
{
return CoRevokeClassObject(dwRegister);
}
HRESULT WINAPI RegisterClassObject(DWORD dwClsContext, DWORD dwFlags)
{
IUnknown* p = NULL;
if (pfnGetClassObject == NULL)
return S_OK;
HRESULT hRes = pfnGetClassObject(pfnCreateInstance, IID_IUnknown, (LPVOID*) &p);
if (SUCCEEDED(hRes))
hRes = CoRegisterClassObject(*pclsid, p, dwClsContext, dwFlags, &dwRegister);
if (p != NULL)
p-> Release();
return hRes;
}
void (WINAPI *pfnObjectMain)(bool bStarting);
};
#define BEGIN_OBJECT_MAP(x) static _ATL_OBJMAP_ENTRY x[] = {
#define END_OBJECT_MAP() {NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL}};
#define OBJECT_ENTRY(clsid, class) {&clsid, class::UpdateRegistry, class::_ClassFactoryCreatorClass::CreateInstance, class::_CreatorClass::CreateInstance, NULL, 0, class::GetObjectDescription, class::GetCategoryMap, class::ObjectMain },
BEGIN_OBJECT_MAP(ObjectMap)
OBJECT_ENTRY(CLSID_Math, CMath)
END_OBJECT_MAP()
这时，ObjectMap数组有几个元素呢？每个分别被填入了什么值？
[解决办法]
ATL？
2个元素
第一个CLSID_Math相关的，将OBJECT_ENTRY 展开就可以了
第二个元素内容是{NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL}表示结尾
