【API】GetUserNameEx 函数使用

BOOLEAN WINAPI GetUserNameEx(  __in          EXTENDED_NAME_FORMAT NameFormat,  __out         LPTSTR lpNameBuffer,  __in_out      PULONG lpnSize);

Header Declared in Secext.h; include Security.h. Library Use Secur32.lib. 

头文件添加：

#include "Security.h"#pragma comment(lib,"Secur32.lib")

C:\WinDDK\7600.16385.1\inc\api\sspi.h(60) : fatal error C1189: #error :   You must define one of SECURITY_WIN32, SECURITY_KERNEL, or

编译这个出现这个错误提示。

在头文件处，添加 如下定义：

#define SECURITY_WIN32

WCHAR wzUser[MAX_PATH] = {0};ULONG ulSize;GetUserNameEx(NameUserPrincipal,wzUser,&ulSize);
