/* This file is part of NLM support for BFD, and contains the portions
|
|
that describe how NLM is represented externally by the BFD library.
|
|
I.E. it describes the in-file representation of NLM. It requires
|
|
the nlm/common.h file which contains the portions that are common to
|
|
both the internal and external representations.
|
|
|
|
Note that an NLM header consists of three parts:
|
|
|
|
(1) A fixed length header that has specific fields of known length,
|
|
at specific offsets in the file.
|
|
|
|
(2) A variable length header that has specific fields in a specific
|
|
order, but some fields may be variable length.
|
|
|
|
(3) A auxiliary header that has various optional fields in no specific
|
|
order. There is no way to identify the end of the auxiliary headers
|
|
except by finding a header without a recognized 'stamp'.
|
|
|
|
The exact format of the fixed length header unfortunately varies
|
|
from one NLM target to another, due to padding. Each target
|
|
defines the correct external format in a separate header file.
