| 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 |
