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 0 ; offset of "foo" in string table
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 */
