dysymtab_command.extrefsymoff

Offset to referenced symbol table.

To support dynamic module binding the module structure for each module indicates the external references (defined and undefined) each module makes. For each module there is an offset and a count into the reference symbol table for the symbols that the module references. This exists only in a dynamically linked shared library file. For executable and object modules the defined external symbols and the undefined external symbols indicates the external references.
