The RtlIsServicePackVersionInstalled routine determines if a specified service pack version of the Microsoft Windows device driver interface (DDI) is installed.

Syntax

BOOLEAN RtlIsServicePackVersionInstalled(
  [in] ULONG Version
);

Parameters

[in] Version

The service pack version of the Windows DDI that is available. The following table lists the possible values for Version.

Constant	Windows version
NTDDI_WIN7	Windows 7 and Windows Server 2008 R2
NTDDI_WS08SP2	Windows Server 2008 with Service Pack 2 (SP2)
NTDDI_WS08	Windows Server 2008
NTDDI_VISTASP2	Windows Vista with SP2
NTDDI_VISTASP1	Windows Vista with SP1
NTDDI_VISTA	Windows Vista
NTDDI_WS03SP2	Windows Server 2003 with SP2
NTDDI_WS03SP1	Windows Server 2003 with SP1
NTDDI_WS03	Windows Server 2003
NTDDI_WINXPSP3	Windows XP with SP3
NTDDI_WINXPSP2	Windows XP with SP2
NTDDI_WINXPSP1	Windows XP with SP1
NTDDI_WINXP	Windows XP
NTDDI_WIN2KSP4	Windows 2000 with SP4
NTDDI_WIN2KSP3	Windows 2000 with SP3
NTDDI_WIN2KSP2	Windows 2000 with SP2
NTDDI_WIN2KSP1	Windows 2000 with SP1
NTDDI_WIN2K	Windows 2000

The NTDDI_XXX constants are defined in the Sdkddkver.h header file. The preceding table does not contain an entry for Windows Server 2008 with SP1. The first service pack to become available for Windows Server 2008 is SP2.

Return value

RtlIsServicePackVersionInstalled returns TRUE if the service pack version of the Windows operating system that is running is the same or later than the version that the Version parameter specifies. Otherwise, this routine returns FALSE. RtlIsServicePackVersionInstalled also returns FALSE if the major version (for example, Windows Vista or Windows Server 2003) that Version specifies does not match the major version of Windows that is currently running on the computer.

Remarks

The RtlIsServicePackVersionInstalled routine compares the version that the Version parameter specifies to the version of the currently running Windows operating system.

Use the RtlIsNtDdiVersionAvailable routine to determine if a major version of Windows is running.

For more information about RtlIsServicePackVersionInstalled and RtlIsNtDdiVersionAvailable, see Header File Changes in the Windows Driver Kit.

The Windows kernel implements RtlIsServicePackVersionInstalled only in Windows Vista and later versions of Windows. However, a compatibility library, Rtlver.lib, implements a version of RtlIsServicePackVersionInstalled that runs in Windows 2000 and later versions of Windows. For kernel-mode drivers that include the Wdm.h header file, calls to RtlIsServicePackVersionInstalled go to the version of this routine that is implemented in Rtlver.lib.
