[Win32 API] Verifying the System Version

Windows의 Version 및 SP 버전을 확인하고자 할 때는 VerifyVersionInfo API를 이용하면 된다.

MSDN에서 발췌해온 아래 샘플을 참고하자.

[Example 1]

#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");
}


[Example 2]

#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");
}
