53 | Sets the SKU value for subsequent calls to set or get PCD token values.\r | |
54 | \r | |
55 | SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values. \r | |
56 | SetSku() is normally called only once by the system.\r | |
57 | \r | |
58 | For each item (token), the database can hold a single value that applies to all SKUs, \r | |
59 | or multiple values, where each value is associated with a specific SKU Id. Items with multiple, \r | |
60 | SKU-specific values are called SKU enabled. \r | |
61 | \r | |
62 | The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255. \r | |
63 | For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the \r | |
64 | single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the \r | |
65 | last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token, \r | |
66 | the system uses the default SKU Id. If the system attempts to use the default SKU Id and no value has been \r | |
67 | set for that Id, the results are unpredictable.\r | |
