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 */
