c獲取系統版本號

 發布時間：2024-11-04 12:15:24

⑴ 如何用C語言獲取主機操作系統的版本號

redhat系統可直接從文件中讀取：cat /etc/redhat-release
windows：
GetUserName(LPWSTR lpBuffer, LPDWORD nSize);
lpBuffer是一個數組的地址，用來存貯得到的用戶名，nsize是個指針，指向此存貯此數組大小的單元，就是數組能存貯的字元數量
GetVersionExW(LPOSVERSIONINFOW);
參數LPOSVERSIONINFO是一個指向OSVERSIONINFO類型變數的指針，
具體判斷代碼如下
定義 OSVERSIONINFO osvi;
然後調用函數取得版本號，判斷如下
switch (osvi.dwPlatformId)
{
case VER_PLATFORM_WIN32_NT:
if (osvi.dwMajorVersion == 5&&osvi.dwMinorVersion == 0)
{
strOSVersion = TEXT("Windows 2000");
}
else if (osvi.dwMajorVersion == 5&&osvi.dwMinorVersion == 1)
{
strOSVersion = TEXT("Windows XP");
}
else if(osvi.dwMajorVersion == 6&&osvi.dwMinorVersion == 0)
{
strOSVersion = TEXT("Windows Vista");
}
else if (osvi.dwMajorVersion == 4&&osvi.dwMinorVersion == 0)
{
strOSVersion = TEXT("Windows NT");
}
break;
case VER_PLATFORM_WIN32_WINDOWS:
if (osvi.dwMajorVersion == 4&&osvi.dwMinorVersion == 10)
{
strOSVersion = TEXT("Windows 98");
}
else if (osvi.dwMajorVersion == 4&&osvi.dwMinorVersion == 90)
{
strOSVersion = TEXT("Windows ME");
}
else
{
strOSVersion = TEXT("Windows 95");
}
break;
default:
break;
}

⑶ C語言如何獲取系統版本就是說win XP，win7還是其他的什麼

調用API 讀取注冊表就OK了
#include <stdio.h>
#include <windows.h>
#include <tchar.h>
int main()
{
TCHAR buf[255];
int size;
HKEY hKey;
DWORD regType = REG_SZ;
LONG ret = RegOpenKeyEx(HKEY_LOCAL_MACHINE,
"SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion",
0,
KEY_READ,
&hKey);
if(ret!=ERROR_SUCCESS)
{
_tprintf(TEXT("%s"), TEXT("無法打開\nHKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion"));
return 1;
}

size = 254;
ret = RegQueryValueEx(hKey, "ProctName",0,®Type,
buf, &size);
if(ret!=ERROR_SUCCESS)
_tprintf(TEXT("%s"), TEXT("無法讀取ProctName"));
else
_tprintf(TEXT("系統:%s\n"), buf);

size = 254;
ret = RegQueryValueEx(hKey, "CSDVersion",0,®Type,
buf, &size);
if(ret!=ERROR_SUCCESS)
_tprintf(TEXT("%s"), TEXT("無法讀取CSDVersion"), TEXT("錯誤"));
else
_tprintf(TEXT("補丁包:%s\n"), buf);

size = 254;
ret = RegQueryValueEx(hKey, "CurrentVersion",0,®Type,
buf, &size);
if(ret!=ERROR_SUCCESS)
_tprintf(TEXT("%s"), TEXT("無法讀取CurrentVersion"), TEXT("錯誤"));
else
_tprintf(TEXT("版本號:%s\n"), buf);

size = 254;
ret = RegQueryValueEx(hKey, "CurrentBuildNumber",0,®Type,
buf, &size);
if(ret!=ERROR_SUCCESS)
_tprintf(TEXT("%s"), TEXT("無法讀取CurrentBuildNumber"), TEXT("錯誤"));
else
_tprintf(TEXT("子版本號:%s\n"), buf);

RegCloseKey(hKey);
return 0;
}

⑷ windows下C/C++如何獲得當前主機的信息：操作系統版本、系統類型、CUP、網卡、內存和磁碟的利用率

示例代碼如下：

GetsysInfo.h：

#ifndef_H_GETSYSINFO
#define_H_GETSYSINFO


#pragmaonce

#include<afxtempl.h>

classGetSysInfo
{
public:
	GetSysInfo(void);
	~GetSysInfo(void);

public:
	/********獲取操作系統版本，Servicepack版本、系統類型************/
	voidGetOSVersion(CString&strOSVersion,CString&strServiceVersion);
	BOOLIsWow64();//判斷是否為64位操作系統

	/***********獲取網卡數目和名字***********/
	intGetInterFaceCount();
	voidGetInterFaceName(CString&InterfaceName,intpNum);

	/***獲取物理內存和虛擬內存大小***/
	voidGetMemoryInfo(CString&dwTotalPhys,CString&dwTotalVirtual);

	/****獲取CPU名稱、內核數目、主頻*******/
	voidGetCpuInfo(CString&chProcessorName,CString&chProcessorType,DWORD&dwNum,DWORD&dwMaxClockSpeed);

	/****獲取硬碟信息****/
	voidGetDiskInfo(DWORD&dwNum,CStringchDriveInfo[]);

	/****獲取顯卡信息*****/
	voidGetDisplayCardInfo(DWORD&dwNum,CStringchCardName[]);
private:
	CStringListInterfaces;		//保存所有網卡的名字
	CList<DWORD,DWORD&>		Bandwidths;	//各網卡的帶寬
	CList<DWORD,DWORD&>		TotalTraffics;//各網卡的總流量
};

#endif
