AVCSTRM_OPEN_STRUCT structure (avcstrm.h)
The AVCSTRM_OPEN_STRUCT structure describes a data stream to be opened.
Syntax
typedef struct _AVCSTRM_OPEN_STRUCT {
KSPIN_DATAFLOW DataFlow;
PAVCSTRM_FORMAT_INFO AVCFormatInfo;
PVOID AVCStreamContext;
HANDLE hPlugLocal;
} AVCSTRM_OPEN_STRUCT, *PAVCSTRM_OPEN_STRUCT;
Members
DataFlow
Specifies the direction of the data-flow.
AVCFormatInfo
Pointer to a description of the subunit stream format.
AVCStreamContext
Pointer to a stream context (handle) that is passed to subsequent avcstrm.sys operations. Its content should not be used or altered.
hPlugLocal
Specifies a local plug created by an AV/C subunit, which is used to connect to the target device.
Remarks
The AVCSTRM_OPEN function code uses this structure to describe the open operation. If the operation is successful, a stream context (handle) is returned to the caller in the AVCStrmContext member of this structure, not the AVCStrmContext member in the AVC_STREAM_REQUEST_BLOCK structure.
This value can then be used in subsequent avcstrm.sys operations by placing it in the AVCStrmContext member of the AVC_STREAM_REQUEST_BLOCK structure.
