17 | /* The Symdef member of an archive contains two things: | |
18 | a table that maps symbol-string offsets to file offsets, | |
19 | and a symbol-string table. All the symbol names are | |
20 | run together (each with trailing null) in the symbol-string | |
21 | table. There is a single longword bytecount on the front | |
22 | of each of these tables. Thus if we have two symbols, | |
23 | "foo" and "_bar", that are in archive members at offsets | |
24 | 200 and 900, it would look like this: | |
25 | 16 ; byte count of index table | |
26 | 0 ; offset of "foo" in string table | |
27 | 200 ; offset of foo-module in file | |
28 | 4 ; offset of "bar" in string table | |
29 | 900 ; offset of bar-module in file | |
30 | 9 ; byte count of string table | |
31 | "foo\0_bar\0" ; string table */ | |
