BOOL GetFileAttributesEx(
LPCTSTR lpFileName, // pointer to string that specifies a
// file or directory
GET_FILEEX_INFO_LEVELS fInfoLevelId,
// value that specifies the type of
// attribute information to obtain
LPVOID lpFileInformation // pointer to buffer to receive
// attribute information
);
那这些变量怎么设置
谁举个例?
