Applies to: desktop apps only

Queries the ranges of data that are either seekable or buffered.

Syntax

HRESULT GetByteRanges(
  [in]   BYTE_RANGE_TYPE ByteRangeType,
  [out]  DWORD *pcRanges,
  [out]  QWORD **pparrStartOffsets,
  [out]  QWORD **pparrEndOffsets
);

Parameters

• ByteRangeType [in]
  The type of byte range to get, specified as a member of the BYTE_RANGE_TYPE enumeration.

• pcRanges [out]
  Receives the number of ranges.

• pparrStartOffsets [out]
  Receives a pointer to an array that contains the start of each range. Each start position is given as a byte offset from the beginning of the byte stream. The size of the array is returned in the pcRanges parameter. The caller must free the array by calling CoTaskMemFree.

• pparrEndOffsets [out]
  Receives a pointer to an array that contains the end of each range. Each end position is given as a byte offset from the beginning of the byte stream. The size of the array is returned in the pcRanges parameter. The caller must free the array by calling CoTaskMemFree.
