37 | Sets the SKU value for subsequent calls to set or get PCD token values.\r | |
38 | \r | |
39 | SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values. \r | |
40 | SetSku() is normally called only once by the system.\r | |
41 | \r | |
42 | For each item (token), the database can hold a single value that applies to all SKUs, \r | |
43 | or multiple values, where each value is associated with a specific SKU Id. Items with multiple, \r | |
44 | SKU-specific values are called SKU enabled. \r | |
45 | \r | |
46 | The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255. \r | |
47 | For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the \r | |
48 | single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the \r | |
49 | last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token, \r | |
50 | the system uses the default SKU Id. If the system attempts to use the default SKU Id and no value has been \r | |
51 | set for that Id, the results are unpredictable.\r | |
52 | \r | |
53 | @param[in] SkuId The SKU value that will be used when the PCD service will retrieve and \r | |
54 | set values associated with a PCD token.\r | |
