0cda46cf | 26 | DESCRIPTION |
4ee249da DHW |
27 | An archive (or library) is just another BFD. It has a symbol |
28 | table, although there's not much a user program will do with it. | |
29 | ||
30 | The big difference between an archive BFD and an ordinary BFD | |
31 | is that the archive doesn't have sections. Instead it has a | |
c188b0be DM |
32 | chain of BFDs that are considered its contents. These BFDs can |
33 | be manipulated like any other. The BFDs contained in an | |
34 | archive opened for reading will all be opened for reading. You | |
4ee249da | 35 | may put either input or output BFDs into an archive opened for |
c188b0be | 36 | output; they will be handled correctly when the archive is closed. |
4ee249da | 37 | |
c188b0be DM |
38 | Use <<bfd_openr_next_archived_file>> to step through |
39 | the contents of an archive opened for input. You don't | |
40 | have to read the entire archive if you don't want | |
4ee249da DHW |
41 | to! Read it until you find what you want. |
42 | ||
43 | Archive contents of output BFDs are chained through the | |
44 | <<next>> pointer in a BFD. The first one is findable through | |
45 | the <<archive_head>> slot of the archive. Set it with | |
c188b0be | 46 | <<bfd_set_archive_head>> (q.v.). A given BFD may be in only one |
4ee249da DHW |
47 | open output archive at a time. |
48 | ||
49 | As expected, the BFD archive code is more general than the | |
50 | archive code of any given environment. BFD archives may | |
287c221d | 51 | contain files of different formats (e.g., a.out and coff) and |
4ee249da DHW |
52 | even different architectures. You may even place archives |
53 | recursively into archives! | |
54 | ||
55 | This can cause unexpected confusion, since some archive | |
287c221d | 56 | formats are more expressive than others. For instance, Intel |
c188b0be | 57 | COFF archives can preserve long filenames; SunOS a.out archives |
4ee249da DHW |
58 | cannot. If you move a file from the first to the second |
59 | format and back again, the filename may be truncated. | |
60 | Likewise, different a.out environments have different | |
61 | conventions as to how they truncate filenames, whether they | |
62 | preserve directory names in filenames, etc. When | |
63 | interoperating with native tools, be sure your files are | |
64 | homogeneous. | |
65 | ||
66 | Beware: most of these formats do not react well to the | |
67 | presence of spaces in filenames. We do the best we can, but | |
c188b0be DM |
68 | can't always handle this case due to restrictions in the format of |
69 | archives. Many Unix utilities are braindead in regards to | |
4ee249da DHW |
70 | spaces and such in filenames anyway, so this shouldn't be much |
71 | of a restriction. | |
c188b0be DM |
72 | |
73 | Archives are supported in BFD in <<archive.c>>. | |

77 | /* Assumes: |
78 | o - all archive elements start on an even boundary, newline padded; | |
79 | o - all arch headers are char *; | |
80 | o - all arch headers are the same size (across architectures). | |
81 | */ | |

4ee249da | 83 | /* Some formats provide a way to cram a long filename into the short |
c188b0be | 84 | (16 chars) space provided by a BSD archive. The trick is: make a |
4ee249da DHW |
85 | special "file" in the front of the archive, sort of like the SYMDEF |
86 | entry. If the filename is too long to fit, put it in the extended | |
87 | name table, and use its index as the filename. To prevent | |
88 | confusion prepend the index with a space. This means you can't | |
c188b0be | 89 | have filenames that start with a space, but then again, many Unix |
4ee249da DHW |
90 | utilities can't handle that anyway. |
91 | ||
92 | This scheme unfortunately requires that you stand on your head in | |
93 | order to write an archive since you need to put a magic file at the | |
94 | front, and need to touch every entry to do so. C'est la vie. | |
b5b4294e JG |
95 | |
96 | We support two variants of this idea: | |
97 | The SVR4 format (extended name table is named "//"), | |
98 | and an extended pseudo-BSD variant (extended name table is named | |
99 | "ARFILENAMES/"). The origin of the latter format is uncertain. | |
100 | ||
101 | BSD 4.4 uses a third scheme: It writes a long filename | |
102 | directly after the header. This allows 'ar q' to work. | |
c188b0be | 103 | We currently can read BSD 4.4 archives, but not write them. |
