IsWindowsXPSP1OrGreater function (versionhelpers.h)
Indicates if the current OS version matches, or is greater than, the Windows XP with Service Pack 1 (SP1) version.
Syntax
VERSIONHELPERAPI IsWindowsXPSP1OrGreater();
Return value
True if the current OS version matches, or is greater than, the Windows XP with SP1 version; otherwise, false.
Remarks
This function does not differentiate between client and server releases. It will return true if the current OS version number is equal to or higher than the version of the client named in the call. For example, a call to IsWindowsXPSP3OrGreater will return true on Windows Server 2008. Applications that need to distinguish between server and client versions of Windows should call IsWindowsServer.
For situations where a Windows Server version number isn't shared with a Windows client release, you can use IsWindowsVersionOrGreater to confirm.
Examples
The inline functions defined in the VersionHelpers.h header file let you verify the operating system version by returning a Boolean value when testing for a version of Windows.
For example, if your application requires Windows XP with SP1 or later, use the following test.
#include <VersionHelpers.h>
…
if (!IsWindowsXPSP1OrGreater())
{
MessageBox(NULL, "You need at least Windows XP with SP1", "Version Not Supported", MB_OK);
}
