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:
- 在 OSVERSIONINFOEX 结构中设置适当的值。
- 使用 VER_SET_CONDITION 宏设置适当的条件掩码。
- 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");
}
