| 19 | /* The Symdef member of an archive contains two things: |
||
| 20 | a table that maps symbol-string offsets to file offsets, |
||
| 21 | and a symbol-string table. All the symbol names are |
||
| 22 | run together (each with trailing null) in the symbol-string |
||
| 23 | table. There is a single longword bytecount on the front |
||
| 24 | of each of these tables. Thus if we have two symbols, |
||
| 25 | "foo" and "_bar", that are in archive members at offsets |
||
| 26 | 200 and 900, it would look like this: |
||
| 27 | 16 ; byte count of index table |
||
| 28 | |||
| 29 | 200 ; offset of foo-module in file |
||
| 30 | 4 ; offset of "bar" in string table |
||
| 31 | 900 ; offset of bar-module in file |
||
| 32 | 9 ; byte count of string table |
||
| 33 | "foo\0_bar\0" ; string table */ |
