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 | |
e4e42b45 | 43 | defines the correct external format in a separate header file. */ |
