锁屏的函数

以下是找不到定义的解决方法

#ifndef WINVER
#define WINVER 0x0400
/*
* If you need Win32 API features newer the Win95 and WinNT then you must
* define WINVER before including windows.h or any other method of including
* the windef.h header.
*/
#endif
#ifndef _WIN32_WINNT
#define _WIN32_WINNT WINVER
/*
* There may be the need to define _WIN32_WINNT to a value different from
* the value of WINVER.  I don't have any example of why you would do that.
* However, if you must then define _WIN32_WINNT to the value required before
* including windows.h or any other method of including the windef.h header.
*/
#endif
明白了。原来_WIN32_WINNT被定义为WINVER，而WINVER又被定义为0x0400，而且要改变两个的值需要在#include 之前。把#define WINVER 0x0500（或者#define _WIN32_WINNT 0x0500）放在最前面，编译，问题解决。（建议使用#define WINVER 0x0500，因为_WIN32_WINNT的说明中要求尽量保持和WINVER的一致。）
