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