365 * Notes for adding new oextra structures:
367 * 1. Add the structure definition and any required macros in an
369 * header file that precedes this one.
370 * 2. Add a pointer to your new struct to the oextra struct in this
372 * 3. Add a referencing macro to this file after the newobj macro above
373 * (see ONAME, OMONST, OMIN, OLONG, or OMAILCMD for examples).
374 * 4. Add a testing macro after the set of referencing macros
375 * (see has_oname(), has_omonst(), has_omin(), has_olong(),
376 * has_omailcmd() for examples).
377 * 5. Create a newXX(otmp) function and possibly a free_XX(otmp)
379 * in an appropriate new or existing source file and add a prototype
380 * for it to include/extern.h. The majority of these are currently
381 * located in mkobj.c for convenience.
383 * void FDECL(newXX, (struct obj *));
384 * void FDECL(free_XX, (struct obj *));
390 * if (!otmp->oextra) otmp->oextra = newoextra();
392 * XX(otmp) = (struct XX *)alloc(sizeof(struct xx));
393 * (void) memset((genericptr_t) XX(otmp),
394 * 0, sizeof(struct xx));
398 * 6. Adjust size_obj() in src/cmd.c appropriately.
399 * 7. Adjust dealloc_oextra() in src/mkobj.c to clean up
400 * properly during obj deallocation.
401 * 8. Adjust copy_oextra() in src/mkobj.c to make duplicate
402 * copies of your struct or data onto another obj struct.
403 * 9. Adjust restobj() in src/restore.c to deal with your
404 * struct or data during a restore.
405 * 10. Adjust saveobj() in src/save.c to deal with your
406 * struct or data during a save.
