Each row of a SymSequencePoint table describes a sequence point, as follows:
| Offset | Size | Field | Description |
|---|---|---|---|
| 0 | 4 | Offset | CIL offset of the sequence point. |
| 4 | 4 | StartLine | Starting line of the source document. |
| 8 | 4 | StartColumn | Starting column, or 0 if not specified. |
| 12 | 4 | EndLine | Ending line of the source document, or 0 if not specified. |
| 16 | 4 | EndColumn | Ending column, or 0 if not specified. |
| 20 | 4 | Doc | Index of the source document in the SymString heap. |
Together, EndLine and EndColumn specify the column "one past" the last byte position associated with the sequence point. In other words, they specify the end of a half-open interval [start,end).
Rows of the SymSequencePoint belonging to the same Method must be contiguous and sorted in ascending order of Offset.
