GetVersionEx

[arrowfly]

开始——运行——winver，就可以知道了。

[freelybird]

// Indicates that the version information is valid.
static BOOL g_bHasVersion = FALSE ;
// Indicates NT or 95/98.
static BOOL g_bIsNT = TRUE ;

BOOL __stdcall IsNT ( void )
{
if ( TRUE == g_bHasVersion )
{
return ( TRUE == g_bIsNT ) ;
}

OSVERSIONINFO stOSVI ;

memset ( &stOSVI , NULL , sizeof ( OSVERSIONINFO ) ) ;
stOSVI.dwOSVersionInfoSize = sizeof ( OSVERSIONINFO ) ;

BOOL bRet = GetVersionEx ( &stOSVI ) ;
ASSERT ( TRUE == bRet ) ;
if ( FALSE == bRet )
{
TRACE0 ( "GetVersionEx failed!\n" ) ;
return ( FALSE ) ;
}

// Check the version and call the appropriate thing.
if ( VER_PLATFORM_WIN32_NT == stOSVI.dwPlatformId )
{
g_bIsNT = TRUE ;
}
else
{
g_bIsNT = FALSE ;
}
g_bHasVersion = TRUE ;
return ( TRUE == g_bIsNT ) ;
}

判断MajorVersion,大于5的是2000,xp不知道

Win32Type ShellType;
DWORD winVer;
OSVERSIONINFO *osvi;

winVer=GetVersion();
if(winVer<0x80000000){/*NT */
ShellType=WinNT3;
osvi= (OSVERSIONINFO *)malloc(sizeof(OSVERSIONINFO));
if (osvi!=NULL){
memset(osvi,0,sizeof(OSVERSIONINFO));
osvi->dwOSVersionInfoSize=sizeof(OSVERSIONINFO);
GetVersionEx(osvi);
if (osvi->dwMajorVersion>=4L)
ShellType=WinNT4orHigher;//yup, it is NT 4 or higher!
free(osvi);
}
}
else if (LOBYTE(LOWORD(winVer))<4)
ShellType=Win32s;/*Win32s*/
else
ShellType=Windoze95;/*Windoze95*/
