module table

indirect symbol table

shared library. For executable and object modules, which are files
|
|
containing only one module, the information that would be in these three
|
|
tables is determined as follows:
|
|
table of contents - the defined external symbols are sorted by name
|
|
module table - the file contains only one module so everything in the
|
|
file is part of the module.
|
|
reference symbol table - is the defined and undefined external symbols
|
|
|
|
For dynamically linked shared library files this load command also contains
|
|
offsets and sizes to the pool of relocation entries for all sections
|
|
separated into two groups:
|

external relocation entries
|
|
local relocation entries
