The Debug library supports debug print and asserts based on a combination of macros and code.
|
||||
The debug library can be turned on and off so that the debug code does not increase the size of an image.
|
||||
|
||||
Note that a MDEPKG_NDEBUG macro is introduced to switch on/off debug and assert related macros.
|
||||
1. If MDEPKG_NDEBUG is defined, then debug and assert related macros are NULL.
|
||||
2. If MDEPKG_NDEBUG is not defined, then PcdDebugProperyMask is used to turn on/off these helper macros.
