/* This is the second set of the symbolic information which is used to support
the data structures for the dynamically link editor.
2002-11-06 14:26:29 +01:00
The original set of symbolic information in the symtab_command which contains
the symbol and string tables must also be present when this load command is
present. When this load command is present the symbol table is organized
into three groups of symbols:
local symbols (static and debugging symbols) - grouped by module
defined external symbols - grouped by module (sorted by name if not lib)
undefined external symbols (sorted by name)
In this load command there are offsets and counts to each of the three groups
of symbols.
2002-11-06 14:26:29 +01:00
This load command contains a the offsets and sizes of the following new
symbolic information tables:
table of contents
module table
reference symbol table
indirect symbol table
The first three tables above (the table of contents, module table and
reference symbol table) are only present if the file is a dynamically linked
2002-11-06 14:26:29 +01:00
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
2002-11-06 14:26:29 +01:00
offsets and sizes to the pool of relocation entries for all sections
separated into two groups:
external relocation entries
local relocation entries
For executable and object modules the relocation entries continue to hang
off the section structures. */
