获取Windows操作系统版本和位数

今天药忘吃喽~ 2022-09-25 01:16 194阅读 0赞

（1）获取系统位数32bit 64bit

void CXXXDlg::GetSysBit(bool& bIs32Bit)
    {
    	bIs32Bit=true;
    	SYSTEM_INFO si;
    	// Copy the hardware information to the SYSTEM_INFO structure.
    	GetNativeSystemInfo(&si);
    	// Display the contents of the SYSTEM_INFO structure.
    	printf("si.wProcessorArchitecture = %d\nPROCESSOR_ARCHITECTURE_AMD64 = %d\nPROCESSOR_ARCHITECTURE_IA64 = %d\n",
    		si.wProcessorArchitecture, PROCESSOR_ARCHITECTURE_AMD64, PROCESSOR_ARCHITECTURE_IA64);
    	if (si.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_AMD64 || si.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_IA64)
    	{
    		bIs32Bit=false;
    	}
    	else{
    		bIs32Bit=true;
    	}
    }

（2）获取系统版本号

前面的博文中已经对Windows操作系统产品名与内部版本号的对应做了总结，参考：[http://blog.csdn.net/shufac/article/details/52088374][http_blog.csdn.net_shufac_article_details_52088374]  
通过下面的函数可以获取版本相关的信息，函数如下：

void  CXXXDlg::GetSysType(DWORD& dwMajorVersion,DWORD& dwMinorVersion)
    {
    	//DWORD dwOSVersionInfoSize;//
    	//DWORD dwMajorVersion;//主版本号
    	//DWORD dwMinorVersion;//副版本
    	//DWORD dwBuildNumber;//创建号
    	//DWORD dwPlatformId;//ID号
    	//WCHAR  szCSDVersion[ 128 ]; //
    	dwMajorVersion=0;
    	dwMinorVersion=0;
    	OSVERSIONINFO osvi;                                                     //定义OSVERSIONINFO数据结构对象
    	memset(&osvi, 0, sizeof(OSVERSIONINFO));                    //开空间 
    	osvi.dwOSVersionInfoSize = sizeof (OSVERSIONINFO);   //定义大小 
    	GetVersionEx (&osvi);                                                        //获得版本信息 
    	dwMajorVersion=osvi.dwMajorVersion;
    	dwMinorVersion=osvi.dwMinorVersion;
    }
