-/* The macros in this file implement forward iteration through a
-   multi-byte string.
-
-   With these macros, an iteration loop that looks like
-
-      char *iter;
-      for (iter = buf; iter < buf + buflen; iter++)
-        {
-          do_something (*iter);
-        }
-
-   becomes
-
-      mbi_iterator_t iter;
-      for (mbi_init (iter, buf, buflen); mbi_avail (iter); mbi_advance (iter))
-        {
-          do_something (mbi_cur_ptr (iter), mb_len (mbi_cur (iter)));
-        }
-
-   The benefit of these macros over plain use of mbrtowc is:
-   - Handling of invalid multibyte sequences is possible without
-     making the code more complicated, while still preserving the
-     invalid multibyte sequences.
-
-   mbi_iterator_t
-     is a type usable for variable declarations.
-
-   mbi_init (iter, startptr, length)
-     initializes the iterator, starting at startptr and crossing length bytes.
-
-   mbi_avail (iter)
-     returns true if there are more multibyte characters available before
-     the end of string is reached. In this case, mbi_cur (iter) is
-     initialized to the next multibyte character.
-
-   mbi_advance (iter)
-     advances the iterator by one multibyte character.
-
-   mbi_cur (iter)
-     returns the current multibyte character, of type mbchar_t.  All the
-     macros defined in mbchar.h can be used on it.
-
-   mbi_cur_ptr (iter)
-     return a pointer to the beginning of the current multibyte character.
-
-   mbi_reloc (iter, ptrdiff)
-     relocates iterator when the string is moved by ptrdiff bytes.
-
-   mbi_copy (&destiter, &srciter)
-     copies srciter to destiter.
-
-   Here are the function prototypes of the macros.
-
-   extern void          mbi_init (mbi_iterator_t iter,
-                                  const char *startptr, size_t length);
-   extern bool          mbi_avail (mbi_iterator_t iter);
-   extern void          mbi_advance (mbi_iterator_t iter);
-   extern mbchar_t      mbi_cur (mbi_iterator_t iter);
-   extern const char *  mbi_cur_ptr (mbi_iterator_t iter);
-   extern void          mbi_reloc (mbi_iterator_t iter, ptrdiff_t ptrdiff);
-   extern void          mbi_copy (mbi_iterator_t *new, const mbi_iterator_t *old);
