AVCCONNECTINFO structure (avc.h)
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.
