ISymUnmanagedWriter::DefineSequencePoints Method

Defines a group of sequence points within the current method. Each starting line and starting column define the start of a statement within a method. Each ending line and ending column define the end of a statement within a method. The arrays should be sorted in increasing order of offsets. The offset is always measured from the start of the method, in bytes.

HRESULT DefineSequencePoints(
    [in] ISymUnmanagedDocumentWriter*  document,
    [in] ULONG32 spCount,
    [in, size_is(spCount)] ULONG32     offsets[],
    [in, size_is(spCount)] ULONG32     lines[],
    [in, size_is(spCount)] ULONG32     columns[],
    [in, size_is(spCount)] ULONG32     endLines[],
    [in, size_is(spCount)] ULONG32     endColumns[]);

Parameters

• document
  [in] The document object for which the sequence points are being defined.

• spCount
  [in] A ULONG32 that that indicates the size of each of the offsets, lines, columns, endLines, and endColumns buffers.

• offsets
  [in] The offset of the sequence points measured from the beginning of the method.

• lines
  [in] The starting line numbers of the sequence points.

• columns
  [in] The starting column numbers of the sequence points.

• endLines
  [in] The ending line numbers of the sequence points. This parameter is optional.

• endColumns
  [in] The ending column numbers of the sequence points. This parameter is optional.

Return Value

S_OK if the method succeeds; otherwise, E_FAIL or some other error code.
