AVCCONNECTINFO structure (avc.h)

  • Article

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

Syntax

typedef struct _AVCCONNECTINFO {
  GUID           DeviceID;
  UCHAR          SubunitAddress[AVCCONNECTINFO_MAX_SUBUNITADDR_LEN];
  ULONG          SubunitPlugNumber;
  KSPIN_DATAFLOW DataFlow;
  HANDLE         hPlug;
  ULONG          UnitPlugNumber;
} AVCCONNECTINFO, *PAVCCONNECTINFO;

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.

hPlug

A plug handle obtained from 61883.sys by the intersect handler according to the bit flags set in the associated AVCPRECONNECTINFO structure for this pin. If the proposed connection is between two subunits within the same unit, this value is NULL.

UnitPlugNumber

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

Remarks

This structure is used only as member inside the AVC_SETCONNECT_INFO structure. It is not used by itself.
