KSPROPERTY_CROSSBAR_PININFO_S structure (ksmedia.h)
The KSPROPERTY_CROSSBAR_PININFO_S structure describes the crossbar pin information for a device.
Syntax
typedef struct {
KSPROPERTY Property;
KSPIN_DATAFLOW Direction;
ULONG Index;
ULONG PinType;
ULONG RelatedPinIndex;
KSPIN_MEDIUM Medium;
} KSPROPERTY_CROSSBAR_PININFO_S, *PKSPROPERTY_CROSSBAR_PININFO_S;
Members
Property
Specifies an initialized KSPROPERTY structure that describes the property set, property ID, and request type.
Direction
Specifies the minidriver-provided direction of data flow for the pin specified in Index. This value can be either KSPIN_DATAFLOW_IN or KSPIN_DATAFLOW_OUT.
Index
Specifies the zero-based index of the pin for which crossbar information is being queried. Input pins are queried separately from output pins.
PinType
Specifies the minidriver-provided type of physical connector. This member must be set to one of the KS_PhysicalConnectorType enumerated values defined in ksmedia.h:
KS_PhysConn_Video_Tuner
KS_PhysConn_Video_Composite
KS_PhysConn_Video_Svideo
KS_PhysConn_Video_RGB
KS_PhysConn_Video_YRYBY
KS_PhysConn_Video_SerialDigital
KS_PhysConn_Video_ParallelDigital
KS_PhysConn_Video_SCSI
KS_PhysConn_Video_AUX
KS_PhysConn_Video_Video_1394
KS_PhysConn_Video_USB
KS_PhysConn_Video_VideoDecoder
KS_PhysConn_Video_VideoEncoder
KS_PhysConn_Video_SCART
KS_PhysConn_Audio_Tuner
KS_PhysConn_Audio_Line
KS_PhysConn_Audio_Misc
KS_PhysConn_Audio_AESDigital
KS_PhysConn_Audio_SPDIFDigital
KS_PhysConn_Audio_SCSI
KS_PhysConn_Audio_AUX
KS_PhysConn_Audio_1394
KS_PhysConn_Audio_USB
KS_PhysConn_Audio_AudioDecoder
RelatedPinIndex
Specifies the optional pin index of a pin that is related to the pin specified in Index. For example, the minidriver can set the RelatedPinIndex to the pin index of the audio stream that goes with a video stream in Index. RelatedPinIndex applies only to pins of the same direction (input or output) as the pin being queried. If no other pins are related to the current pin, the minidriver should return (-1).
Medium
Specifies a KSPIN_MEDIUM structure that represents the hardware connection for the pin. This information is returned by the minidriver.
Remarks
All index values are zero-based, and input pins are counted separately from output pins.
