| /** @file | |
| Provides library services to get and set Platform Configuration Database entries. | |
| PCD Library Class provides a PCD usage macro interface for all PCD types. | |
| It should be included in any module that uses PCD. If a module uses dynamic/dynamicex | |
| PCD, module should be linked to a PEIM/DXE library instance to access that PCD. | |
| If a module uses PatchableInModule type PCD, it also needs the library instance to produce | |
| LibPatchPcdSetPtr() interface. For FeatureFlag/Fixed PCD, the macro interface is | |
| translated to a variable or macro that is auto-generated by build tool in | |
| module's autogen.h/autogen.c. | |
| The PcdGetXX(), PcdSetXX(), PcdToken(), and PcdGetNextTokenSpace() operations are | |
| only available prior to ExitBootServices(). If access to PCD values are required | |
| at runtime, then their values must be collected prior to ExitBootServices(). | |
| There are no restrictions on the use of FeaturePcd(), FixedPcdGetXX(), | |
| PatchPcdGetXX(), and PatchPcdSetXX(). | |
