25 | SECTION | |
26 | Archives | |
27 | ||
28 | DESCRIPTION | |
29 | An archive (or library) is just another BFD. It has a symbol | |
30 | table, although there's not much a user program will do with it. | |
31 | ||
32 | The big difference between an archive BFD and an ordinary BFD | |
33 | is that the archive doesn't have sections. Instead it has a | |
34 | chain of BFDs that are considered its contents. These BFDs can | |
35 | be manipulated like any other. The BFDs contained in an | |
36 | archive opened for reading will all be opened for reading. You | |
37 | may put either input or output BFDs into an archive opened for | |
38 | output; they will be handled correctly when the archive is closed. | |
39 | ||
40 | Use <<bfd_openr_next_archived_file>> to step through | |
41 | the contents of an archive opened for input. You don't | |
42 | have to read the entire archive if you don't want | |
43 | to! Read it until you find what you want. | |
44 | ||
45 | Archive contents of output BFDs are chained through the | |
46 | <<next>> pointer in a BFD. The first one is findable through | |
47 | the <<archive_head>> slot of the archive. Set it with | |
48 | <<bfd_set_archive_head>> (q.v.). A given BFD may be in only one | |
49 | open output archive at a time. | |
50 | ||
51 | As expected, the BFD archive code is more general than the | |
52 | archive code of any given environment. BFD archives may | |
53 | contain files of different formats (e.g., a.out and coff) and | |
54 | even different architectures. You may even place archives | |
55 | recursively into archives! | |
56 | ||
57 | This can cause unexpected confusion, since some archive | |
58 | formats are more expressive than others. For instance, Intel | |
59 | COFF archives can preserve long filenames; SunOS a.out archives | |
60 | cannot. If you move a file from the first to the second | |
61 | format and back again, the filename may be truncated. | |
62 | Likewise, different a.out environments have different | |
63 | conventions as to how they truncate filenames, whether they | |
64 | preserve directory names in filenames, etc. When | |
65 | interoperating with native tools, be sure your files are | |
66 | homogeneous. | |
67 | ||
68 | Beware: most of these formats do not react well to the | |
69 | presence of spaces in filenames. We do the best we can, but | |
70 | can't always handle this case due to restrictions in the format of | |
71 | archives. Many Unix utilities are braindead in regards to | |
72 | spaces and such in filenames anyway, so this shouldn't be much | |
73 | of a restriction. | |
74 | ||
75 | Archives are supported in BFD in <<archive.c>>. | |

81 | /* Assumes: | |
82 | o - all archive elements start on an even boundary, newline padded; | |
83 | o - all arch headers are char *; | |
84 | o - all arch headers are the same size (across architectures). | |
85 | */ | |
86 | ||
87 | /* Some formats provide a way to cram a long filename into the short | |
88 | (16 chars) space provided by a BSD archive. The trick is: make a | |
89 | special "file" in the front of the archive, sort of like the SYMDEF | |
90 | entry. If the filename is too long to fit, put it in the extended | |
91 | name table, and use its index as the filename. To prevent | |
92 | confusion prepend the index with a space. This means you can't | |
93 | have filenames that start with a space, but then again, many Unix | |
94 | utilities can't handle that anyway. | |
95 | ||
96 | This scheme unfortunately requires that you stand on your head in | |
97 | order to write an archive since you need to put a magic file at the | |
98 | front, and need to touch every entry to do so. C'est la vie. | |
99 | ||
100 | We support two variants of this idea: | |
101 | The SVR4 format (extended name table is named "//"), | |
102 | and an extended pseudo-BSD variant (extended name table is named | |
103 | "ARFILENAMES/"). The origin of the latter format is uncertain. | |
104 | ||
105 | BSD 4.4 uses a third scheme: It writes a long filename | |
106 | directly after the header. This allows 'ar q' to work. | |

115 | Long name table (must be before regular file members): | |
116 | "// " - Long name table, System 5 R4 style. | |

123 | Regular files with long names (or embedded spaces, for BSD variants): | |
124 | "/18 " - SVR4 style, name at offset 18 in name table. | |
390c0e42 | 125 | "#1/23 " - Long name (or embedded spaces) 23 characters long, |
252b5132 | 126 | BSD 4.4 style, full name follows header. |

127 | " 18 " - Long name 18 characters long, extended pseudo-BSD. |
