The UPDATE_FLAG enumeration controls the behavior of the IDCRL.
The following table describes the values in this enumeration.
Deprecated. Use UPDATE_DEFAULT instead.
Indicates that the client application does not use the IDCRL built-in user interface (UI). When this flag is specified, the UI dynamic-link library (DLL) is not opened (or downloaded) and methods that depend on the UI can not be called.
Any UI-based method that is called after IDCRL has been initialized using the NO_UI flag returns a PPCRL_E_NO_UI_MODE error code.
IDCRL first tries to authenticate online, but if not available, then tries to authenticate off-line. This is the default IDCRL behavior.
Reserved. Do not use.
