C/C++获得windows版本

MSDN上有详细介绍，做个标记：

  #include <windows.h>
  #include <stdio.h>
  
  void main()
  {
      OSVERSIONINFO osvi;
      BOOL bIsWindowsXPorLater;
  
      ZeroMemory(&osvi, sizeof(OSVERSIONINFO));
      osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
  
      GetVersionEx(&osvi);
  
      bIsWindowsXPorLater = 
         ( (osvi.dwMajorVersion > 5) ||
         ( (osvi.dwMajorVersion == 5) && (osvi.dwMinorVersion >= 1) ));
  
      if(bIsWindowsXPorLater)
          printf("The system meets the requirements.\n");
      else printf("The system does not meet the requirements.\n");
  }
