验证系统版本

[ 不建议使用 VerifyVersionInfo 函数来验证当前运行的操作系统。 请改用 版本帮助程序 API]

其中包含使用 VerifyVersionInfo 函数确定应用程序是否在特定操作系统上运行的示例。

每个示例中main步骤如下所示：

1. 在 OSVERSIONINFOEX 结构中设置适当的值。
2. 使用 VER_SET_CONDITION 宏设置适当的条件掩码。
3. 调用 VerifyVersionInfo 以执行测试。

示例 1

以下示例确定应用程序是在 Service Pack 2 (SP2) 或更高版本的 Windows（如 Windows Server 2003 或 Windows Vista）上运行的。

#include <windows.h>
#include <stdio.h>

BOOL Is_WinXP_SP2_or_Later () 
{
   OSVERSIONINFOEX osvi;
   DWORDLONG dwlConditionMask = 0;
   int op=VER_GREATER_EQUAL;

   // Initialize the OSVERSIONINFOEX structure.

   ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
   osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
   osvi.dwMajorVersion = 5;
   osvi.dwMinorVersion = 1;
   osvi.wServicePackMajor = 2;
   osvi.wServicePackMinor = 0;

   // Initialize the condition mask.

   VER_SET_CONDITION( dwlConditionMask, VER_MAJORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_MINORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMAJOR, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMINOR, op );

   // Perform the test.

   return VerifyVersionInfo(
      &osvi, 
      VER_MAJORVERSION | VER_MINORVERSION | 
      VER_SERVICEPACKMAJOR | VER_SERVICEPACKMINOR,
      dwlConditionMask);
}

void main()
{
    if(Is_WinXP_SP2_or_Later())
        printf("The system meets the requirements.\n");
    else printf("The system does not meet the requirements.\n");
}

示例 2

以下代码验证应用程序是否在 Windows 2000 Server 或更高版本的服务器（如 Windows Server 2003 或 Windows Server 2008）上运行。

#include <windows.h>
#include <stdio.h>

BOOL Is_Win_Server() 
{
   OSVERSIONINFOEX osvi;
   DWORDLONG dwlConditionMask = 0;
   int op=VER_GREATER_EQUAL;

   // Initialize the OSVERSIONINFOEX structure.

   ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
   osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);
   osvi.dwMajorVersion = 5;
   osvi.dwMinorVersion = 0;
   osvi.wServicePackMajor = 0;
   osvi.wServicePackMinor = 0;
   osvi.wProductType = VER_NT_SERVER;

   // Initialize the condition mask.

   VER_SET_CONDITION( dwlConditionMask, VER_MAJORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_MINORVERSION, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMAJOR, op );
   VER_SET_CONDITION( dwlConditionMask, VER_SERVICEPACKMINOR, op );
   VER_SET_CONDITION( dwlConditionMask, VER_PRODUCT_TYPE, VER_EQUAL );

   // Perform the test.

   return VerifyVersionInfo(
      &osvi, 
      VER_MAJORVERSION | VER_MINORVERSION | 
      VER_SERVICEPACKMAJOR | VER_SERVICEPACKMINOR |
      VER_PRODUCT_TYPE,
      dwlConditionMask);
}

void main()
{
    if(Is_Win_Server())
        printf("The system meets the requirements.\n");
    else printf("The system does not meet the requirements.\n");
}
