23 | /* This file is part of NLM support for BFD, and contains the portions |
||
24 | that describe how NLM is represented externally by the BFD library. |
||
25 | I.E. it describes the in-file representation of NLM. It requires |
||
26 | the nlm/common.h file which contains the portions that are common to |
||
27 | both the internal and external representations. |
||
28 | |||
29 | Note that an NLM header consists of three parts: |
||
30 | |||
31 | (1) A fixed length header that has specific fields of known length, |
||
32 | at specific offsets in the file. |
||
33 | |||
34 | (2) A variable length header that has specific fields in a specific |
||
35 | order, but some fields may be variable length. |
||
36 | |||
37 | (3) A auxiliary header that has various optional fields in no specific |
||
38 | order. There is no way to identify the end of the auxiliary headers |
||
39 | except by finding a header without a recognized 'stamp'. |
||
40 | |||
41 | The exact format of the fixed length header unfortunately varies |
||
42 | from one NLM target to another, due to padding. Each target |
||
43 | defines the correct external format in a separate header file. */ |
