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