AVCPRECONNECTINFO structure (avc.h)

  • Article

The AVCPRECONNECTINFO structure is used to initialize a subunit driver and establish pin connections.

Syntax

typedef struct _AVCPRECONNECTINFO {
  GUID           DeviceID;
  UCHAR          SubunitAddress[AVCCONNECTINFO_MAX_SUBUNITADDR_LEN];
  ULONG          SubunitPlugNumber;
  KSPIN_DATAFLOW DataFlow;
  ULONG          Flags;
  ULONG          UnitPlugNumber;
} AVCPRECONNECTINFO, *PAVCPRECONNECTINFO;

Members

DeviceID

A GUID representing the unit as a whole. All subunits within the same unit share the same GUID. No two units share the same GUID.

SubunitAddress[AVCCONNECTINFO_MAX_SUBUNITADDR_LEN]

The encoded subunit type and subunit ID of the subunit.

SubunitPlugNumber

The plug number (within the subunit) described by the AVCPRECONNECTINFO structure.

DataFlow

The direction of data flow on this subunit plug. Destination plugs have KSPIN_DATAFLOW_IN; source plugs have KSPIN_DATAFLOW_OUT.

Flags

A bitmap with one or more bits set from the KSPIN_FLAG_AVC enumeration.

UnitPlugNumber

The plug number (within the subunit) described by the AVCPRECONNECTINFO structure.

Remarks

This structure is used with the AVC_FUNCTION_GET_CONNECTINFO function code.

This structure is used only as member of the AVC_PRECONNECT_INFO structure. It is not used by itself.

Requirements
