124 | The original set of symbolic information in the symtab_command which contains |
125 | the symbol and string tables must also be present when this load command is | |
126 | present. When this load command is present the symbol table is organized | |
127 | into three groups of symbols: | |
128 | local symbols (static and debugging symbols) - grouped by module | |
129 | defined external symbols - grouped by module (sorted by name if not lib) | |
130 | undefined external symbols (sorted by name) | |
131 | In this load command there are offsets and counts to each of the three groups | |
132 | of symbols. | |
e84d6fca | 133 | |
3af9a47b NC |
134 | This load command contains a the offsets and sizes of the following new |
135 | symbolic information tables: | |
136 | table of contents | |
137 | module table | |
138 | reference symbol table | |
139 | indirect symbol table | |
140 | The first three tables above (the table of contents, module table and | |
7dee875e | 141 | reference symbol table) are only present if the file is a dynamically linked |
3af9a47b NC |
142 | shared library. For executable and object modules, which are files |
143 | containing only one module, the information that would be in these three | |
144 | tables is determined as follows: | |
145 | table of contents - the defined external symbols are sorted by name | |
146 | module table - the file contains only one module so everything in the | |
147 | file is part of the module. | |
148 | reference symbol table - is the defined and undefined external symbols | |
e84d6fca | 149 | |
7dee875e | 150 | For dynamically linked shared library files this load command also contains |
3af9a47b NC |
151 | offsets and sizes to the pool of relocation entries for all sections |
152 | separated into two groups: | |
153 | external relocation entries | |
154 | local relocation entries | |
155 | For executable and object modules the relocation entries continue to hang | |
156 | off the section structures. */ | |
