|
columnid | Gets the columnid ID that was enumerated. |
|
err | Gets the column status code that results from the enumeration. |

pvData | Gets the value that was enumerated for the column. This member is only used if err is equal to ColumnSingleValue. This points to memory allocated with the JET_PFNREALLOC allocator callback passed to JetEnumerateColumns(JET_SESID, JET_TABLEID, Int32, [], Int32, [], JET_PFNREALLOC, IntPtr, Int32, EnumerateColumnsGrbit). Remember to release the memory when finished. |
