The GetRecordIsPathSelectBitSet method queries whether the path_select bit is set for a particular record in the VCT.

Syntax

HRESULT GetRecordIsPathSelectBitSet(
  [in]   DWORD dwRecordIndex,
  [out]  BOOL *pfVal
);

Parameters

dwRecordIndex [in]
Specifies the record number, indexed from zero. Call the IATSC_VCT::GetCountOfRecords method to get the number of records in the VCT.
pfVal [out]
Receives a Boolean value. The value is TRUE if the path_select bit is set, or FALSE otherwise. The path_select bit indicates which physical input cable carries the transport stream.
