391 * Notes for adding new oextra structures:
393 * 1. Add the structure definition and any required macros in an
394 * appropriate header file that precedes this one.
395 * 2. Add a pointer to your new struct to oextra struct in this file.
396 * 3. Add a referencing macro to this file after the newobj macro above
397 * (see ONAME, OMONST, OMIN, OLONG, or OMAILCMD for examples).
398 * 4. Add a testing macro after the set of referencing macros
399 * (see has_oname(), has_omonst(), has_omin(), has_olong(),
400 * has_omailcmd() for examples).
401 * 5. Create newXX(otmp) function and possibly free_XX(otmp) function
402 * in an appropriate new or existing source file and add a prototype
403 * for it to include/extern.h. The majority of these are currently
404 * located in mkobj.c for convenience.
406 * void FDECL(newXX, (struct obj *));
407 * void FDECL(free_XX, (struct obj *));
413 * if (!otmp->oextra) otmp->oextra = newoextra();
415 * XX(otmp) = (struct XX *)alloc(sizeof(struct xx));
416 * (void) memset((genericptr_t) XX(otmp),
417 * 0, sizeof(struct xx));
421 * 6. Adjust size_obj() in src/cmd.c appropriately.
422 * 7. Adjust dealloc_oextra() in src/mkobj.c to clean up
423 * properly during obj deallocation.
424 * 8. Adjust copy_oextra() in src/mkobj.c to make duplicate
425 * copies of your struct or data onto another obj struct.
426 * 9. Adjust restobj() in src/restore.c to deal with your
427 * struct or data during a restore.
428 * 10. Adjust saveobj() in src/save.c to deal with your
429 * struct or data during a save.
