RegisterClass 函数
注册窗口类，为后面调用 CreateWindow 和 CreateWindowEx 提供基础。
注意：RegisterClass函数已经升级成 RegisterClassEx ，如果不需要设置窗口类小图标，仍然可以用RegisterClass。
函数原型：
ATOM WINAPI RegisterClass (
const WNDCLASS * lpWndClass );
参数
lpWndClass
返回值
类型：ATOM
如果成功，返回唯一标识窗口类的ATOM类型标识符。
如果失败，返回0。
如果失败，返回0。
备注
窗口显示内容根据语言、系统等情况稍有不同。
