23 | SECTION | |
24 | Archives | |
25 | ||
26 | DESCRIPTION | |
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 | |
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 | |
35 | may put either input or output BFDs into an archive opened for | |
36 | output; they will be handled correctly when the archive is closed. | |
37 | ||
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 | |
41 | to! Read it until you find what you want. | |
42 | ||
eeb1f9ae AM |
43 | A BFD returned by <<bfd_openr_next_archived_file>> can be |
44 | closed manually with <<bfd_close>>. If you do not close it, | |
45 | then a second iteration through the members of an archive may | |
46 | return the same BFD. If you close the archive BFD, then all | |
47 | the member BFDs will automatically be closed as well. | |
48 | ||
252b5132 | 49 | Archive contents of output BFDs are chained through the |
eeb1f9ae AM |
50 | <<archive_next>> pointer in a BFD. The first one is findable |
51 | through the <<archive_head>> slot of the archive. Set it with | |
52 | <<bfd_set_archive_head>> (q.v.). A given BFD may be in only | |
53 | one open output archive at a time. | |
252b5132 RH |
54 | |
55 | As expected, the BFD archive code is more general than the | |
56 | archive code of any given environment. BFD archives may | |
57 | contain files of different formats (e.g., a.out and coff) and | |
58 | even different architectures. You may even place archives | |
59 | recursively into archives! | |
60 | ||
61 | This can cause unexpected confusion, since some archive | |
62 | formats are more expressive than others. For instance, Intel | |
63 | COFF archives can preserve long filenames; SunOS a.out archives | |
64 | cannot. If you move a file from the first to the second | |
65 | format and back again, the filename may be truncated. | |
66 | Likewise, different a.out environments have different | |
67 | conventions as to how they truncate filenames, whether they | |
68 | preserve directory names in filenames, etc. When | |
69 | interoperating with native tools, be sure your files are | |
70 | homogeneous. | |
71 | ||
72 | Beware: most of these formats do not react well to the | |
73 | presence of spaces in filenames. We do the best we can, but | |
74 | can't always handle this case due to restrictions in the format of | |
75 | archives. Many Unix utilities are braindead in regards to | |
76 | spaces and such in filenames anyway, so this shouldn't be much | |
77 | of a restriction. | |
78 | ||
79 | Archives are supported in BFD in <<archive.c>>. | |

85 | /* Assumes: | |
86 | o - all archive elements start on an even boundary, newline padded; | |
87 | o - all arch headers are char *; | |
88 | o - all arch headers are the same size (across architectures). | |
89 | */ | |
90 | ||
91 | /* Some formats provide a way to cram a long filename into the short | |
92 | (16 chars) space provided by a BSD archive. The trick is: make a | |
93 | special "file" in the front of the archive, sort of like the SYMDEF | |
94 | entry. If the filename is too long to fit, put it in the extended | |
95 | name table, and use its index as the filename. To prevent | |
96 | confusion prepend the index with a space. This means you can't | |
97 | have filenames that start with a space, but then again, many Unix | |
98 | utilities can't handle that anyway. | |
99 | ||
100 | This scheme unfortunately requires that you stand on your head in | |
101 | order to write an archive since you need to put a magic file at the | |
102 | front, and need to touch every entry to do so. C'est la vie. | |
103 | ||
104 | We support two variants of this idea: | |
105 | The SVR4 format (extended name table is named "//"), | |
106 | and an extended pseudo-BSD variant (extended name table is named | |
107 | "ARFILENAMES/"). The origin of the latter format is uncertain. | |
108 | ||
109 | BSD 4.4 uses a third scheme: It writes a long filename | |
110 | directly after the header. This allows 'ar q' to work. | |

115 | Symbol table (must be first): | |

118 | ||
119 | Long name table (must be before regular file members): | |
120 | "// " - Long name table, System 5 R4 style. | |
121 | "ARFILENAMES/ " - Long name table, non-standard extended BSD (not BSD 4.4). | |
122 | ||
123 | Regular file members with short names: | |
124 | "filename.o/ " - Regular file, System 5 style (embedded spaces ok). | |
125 | "filename.o " - Regular file, Berkeley style (no embedded spaces). | |
126 | ||
127 | Regular files with long names (or embedded spaces, for BSD variants): | |
128 | "/18 " - SVR4 style, name at offset 18 in name table. | |
390c0e42 | 129 | "#1/23 " - Long name (or embedded spaces) 23 characters long, |
252b5132 | 130 | BSD 4.4 style, full name follows header. |
252b5132 RH |
131 | " 18 " - Long name 18 characters long, extended pseudo-BSD. |
