KSPROPERTY_CROSSBAR_ROUTE_S structure

The KSPROPERTY_CROSSBAR_ROUTE_S structure describes whether a particular routing is possible and specifies the current routing for a pin.

Syntax


typedef struct {
  KSPROPERTY Property;
  ULONG      IndexInputPin;
  ULONG      IndexOutputPin;
  ULONG      CanRoute;
} KSPROPERTY_CROSSBAR_ROUTE_S, *PKSPROPERTY_CROSSBAR_ROUTE_S;

Members

Property

Specifies an initialized KSPROPERTY structure that describes the property set, property ID, and request type.

IndexInputPin

Specifies the zero-based index of the input pin for which the query is being made.

IndexOutputPin

Specifies the zero-based index of the output pin for which the query is being made.

CanRoute

Returns whether the minidriver supports routing between the pins specified by IndexInputPin and IndexOutputPin. A nonzero value indicates that routing is supported. If the minidriver does not support routing between the two pins, this value is zero.

Remarks

If the value of IndexInputPin is (-1) on an audio output pin, then the audio stream should be muted.
