| 18 | /* The Symdef member of an archive contains two things: | |
| 19 | a table that maps symbol-string offsets to file offsets, | |
| 20 | and a symbol-string table. All the symbol names are | |
| 21 | run together (each with trailing null) in the symbol-string | |
| 22 | table. There is a single longword bytecount on the front | |
| 23 | of each of these tables. Thus if we have two symbols, | |
| 24 | "foo" and "_bar", that are in archive members at offsets | |
| 25 | 200 and 900, it would look like this: | |
| 26 | 16 ; byte count of index table | |
| 27 | 0 ; offset of "foo" in string table | |
| 28 | 200 ; offset of foo-module in file | |
| 29 | 4 ; offset of "bar" in string table | |
| 30 | 900 ; offset of bar-module in file | |
| 31 | 9 ; byte count of string table | |
| 32 | "foo\0_bar\0" ; string table */ | |
