/** @file
|
|
Provides library services to get and set Platform Configuration Database entries.
|
|
|
|
PCD Library Class provides PCD usage macro interface for all PCD types.
|
|
It should be included at any module who use PCD. If module use dynamic/dynamicex
|
|
PCD, module should be linked to PEIM/DXE library instance to access that PCD.
|
|
If module uses PatchableInModule type PCD, also need library instance produce
|
|
LibPatchPcdSetPtr() interface. For FeatureFlag/Fixed PCD, macro interface is
|
|
translated to an variable or macro which 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().
