KSDEGRADE structure

The KSDEGRADE structure contains specifics of degradation strategies.

Note

The KSDEGRADE typedef is an alias for the KSIDENTIFIER structure. Dengan demikian, definisi mereka identik.

Syntax

struct KSDEGRADE {
  GUID Set;
  ULONG Id;
  ULONG Flags;
};

Members

Set

Menentukan pengidentifikasi set unik global.

Id

Menentukan pengidentifikasi khusus set untuk item dalam set.

Flags

Berisi nilai ULONG yang menentukan persentase degradasi saat ini, yang dinyatakan dalam bagian per seribu (di mana nilai 1000 tidak mewakili degradasi), atau menentukan jumlah waktu dalam unit asli seperti yang ditentukan oleh antarmuka.

Remarks

The Flags member can contain different values based on the type of signal degradation that the client employs. See Quality Management for more details on different strategies for solving quality management problems by reducing signal quality.

Because Flags contains a ULONG value, multiple Skip requests may be needed to remedy a quality management issue.

Requirements

Header: ks.h (include Ks.h)
