Module Name:
EfiDebug.h
Abstract:
EFI Debug macros. The work needs tobe done in library. The Debug
macros them selves are standard for all files, including the core.
There needs to be code linked in that produces the following macros:
EfiDebugAssert(file, linenumber, assertion string) - worker function for
ASSERT. filename and line number of where this ASSERT() is located
is passed in along with the stringized version of the assertion.
EfiDebugPrint - Worker function for debug print
_DEBUG_SET_MEM(address, length, value) - Set memory at address to value
for legnth bytes. This macro is used to initialzed uninitialized memory
or memory that is free'ed, so it will not be used by mistake.
