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