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  */ #define	RANLIBMAG	"__.SYMDEF"	/* Archive file name containing index */#define	RANLIBSKEW	3		/* Creation time offset */ /* Format of __.SYMDEF:   First, a longword containing the size of the 'symdef' data that follows.
