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.
