Each row of a SymVariable table describes a local variable.
| Offset | Size | Field | Description |
|---|---|---|---|
| 0 | 4 | Scope | Index of the parent scope |
| 4 | 4 | Name | Index of the variable's name in the SymString heap. |
| 8 | 4 | Attributes | Flags describing the variable (see below). |
| 12 | 4 | Signature | Index of the signature in the SymMisc heap. |
| 16 | 4 | SignatureSize | Length of the signature. |
| 20 | 4 | AddressKind | Always 1. |
| 24 | 4 | Address1 | Local variable number. |
| 28 | 4 | Address2 | Always 0. |
| 32 | 4 | Address3 | Always 0. |
| 36 | 4 | StartOffset | CIL offset where the variable is first visible. |
| 40 | 4 | EndOffset | CIL offset where the variable is last visible. |
| 44 | 4 | Sequence | Always 0. |
| 48 | 4 | IsParam | Always 0. |
| 52 | 4 | IsHidden | 1 if variable should be hidden from debugger; 0 otherwise. |
The least-significant bit of Attributes indicates whether the variable is user-generated (0) or compiler-generated (1). The other bits are reserved and should be set to zero.
Because parameters are fully described by the Metadata, they do not appear in the SymVariable table.
