  14.   *  Adding new mextra structures:
  15.   *
  16.   *       1. Add the structure definition and any required macros in this
  17.   *          file above the mextra struct.
  18.   *       2. Add a pointer to your new struct to the mextra struct in this
  19.   *          file.
  20.   *       3. Add a referencing macro at bottom of this file after the mextra
  21.   *          struct (see MNAME, EGD, EPRI, ESHK, EMIN, or EDOG for examples).
  22.   *       4. Create a newXX(mtmp) function and possibly a free_XX(mtmp)
  23.   *          function in an appropriate new or existing source file and add
  24.   *          a prototype for it to include/extern.h.
  25.   *
  26.   *              void FDECL(newXX, (struct monst *));
  27.   *              void FDECL(free_XX, (struct monst *));
  28.   *
  29.   *              void
  30.   *              newXX(mtmp)
  31.   *              struct monst *mtmp;
  32.   *              {
  33.   *                  if (!mtmp->mextra)
  34.   *                      mtmp->mextra = newmextra();
  35.   *                  if (!XX(mtmp)) {
  36.   *                      XX(mtmp) = (struct XX *) alloc(sizeof (struct XX));
  37.   *                      (void) memset((genericptr_t) XX(mtmp),
  38.   *                                    0, sizeof (struct XX));
  39.   *                  }
  40.   *              }
  41.   *
  42.   *       5. Consider adding a new makemon flag MM_XX flag to include/hack.h
  43.   *          and a corresponding change to makemon() if you require your
  44.   *          structure to be added at monster creation time.  Initialize your
  45.   *          struct after a successful return from makemon().
  46.   *
  47.   *              src/makemon.c:  if (mmflags & MM_XX) newXX(mtmp);
  48.   *              your new code:  mon = makemon(&mons[mnum], x, y, MM_XX);
  49.   *
  50.   *       6. Adjust size_monst() in src/cmd.c appropriately.
  51.   *       7. Adjust dealloc_mextra() in src/mon.c to clean up
  52.   *          properly during monst deallocation.
  53.   *       8. Adjust copy_mextra() in src/mon.c to make duplicate
  54.   *          copies of your struct or data on another monst struct.
  55.   *       9. Adjust restmon() in src/restore.c to deal with your
  56.   *          struct or data during a restore.
  57.   *      10. Adjust savemon() in src/save.c to deal with your
  58.   *          struct or data during a save.
