171 | The original set of symbolic information in the symtab_command which contains |

175 | local symbols (static and debugging symbols) - grouped by module | |
176 | defined external symbols - grouped by module (sorted by name if not lib) | |
177 | undefined external symbols (sorted by name) | |

179 | of symbols. | |

184 | module table | |
185 | reference symbol table | |

187 | The first three tables above (the table of contents, module table and | |
7dee875e | 188 | reference symbol table) are only present if the file is a dynamically linked |
3af9a47b NC |
189 | shared library. For executable and object modules, which are files |
190 | containing only one module, the information that would be in these three | |
191 | tables is determined as follows: | |
192 | table of contents - the defined external symbols are sorted by name | |
193 | module table - the file contains only one module so everything in the | |
194 | file is part of the module. | |
195 | reference symbol table - is the defined and undefined external symbols | |
e84d6fca | 196 | |
7dee875e | 197 | For dynamically linked shared library files this load command also contains |
3af9a47b NC |
198 | offsets and sizes to the pool of relocation entries for all sections |
199 | separated into two groups: | |
