| /* 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. */ |
