/* 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 */
