Hi Joshua and Stephen, I happened to have one more question about the link & expand process. Now that once the link process is complete, the base.p_xxx tables would be "complete", that is, it would not only contain all identifiers defined in p_xxx tables of all modules(AKA, the global block of a module), but also all identifiers defined in avrule_decl_t.symtab[] for all block/decl of all modules. Then, why would we need to duplicate user/role/type identifiers in a block/decl to its counterpart in the base module? Furthermore, why would we have to copy them once again to the out module? Maybe the answer would be quite obvious, but I may need your hint to break it through :-) Please also refer to the attached pdf for a picture I've drawn for the copy/merge of symtabs during link & expand. Many thanks for your time! Best regards, Harry |
