HRESULT get_virtualBaseTableType(
IDiaSymbol *pRetVal
};
Parameters
| Parameter | Description |

pRetVal |
[out] Returns an IDiaSymbol object that specifies the type of base table. |
Return Value
If successful, returns S_OK; otherwise, returns S_FALSE or an error code.

Remarks
A virtual base table pointer (vbtptr) is a hidden pointer in a Visual C++ vtable that handles inheritance from virtual base classes. A vbtptr can have different sizes depending on the inherited classes.
This method returns an IDiaSymbol object that can be used to determine the size of the vbtptr.
