| 26 | \r |
| 27 | SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values. \r |
| 28 | SetSku() is normally called only once by the system.\r |
| 29 | \r |
| 30 | For each item (token), the database can hold a single value that applies to all SKUs, \r |
| 31 | or multiple values, where each value is associated with a specific SKU Id. Items with multiple, \r |
| 32 | SKU-specific values are called SKU enabled. \r |
| 33 | \r |
| 34 | The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255. \r |
| 35 | For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the \r |
| 36 | single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the \r |
| 37 | last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token, \r |
| 38 | the system uses the default SKU Id. If the system attempts to use the default SKU Id and no value has been \r |
| 39 | set for that Id, the results are unpredictable.\r |
