69 70 * rune_t is declared to be an ``int'' instead of the more natural
70 71 * ``unsigned long'' or ``long''. Two things are happening here. It is not
71 72 * unsigned so that EOF (-1) can be naturally assigned to it and used. Also,
72 73 * it looks like 10646 will be a 31 bit standard. This means that if your
73 74 * ints cannot hold 32 bits, you will be in trouble. The reason an int was
74 75 * chosen over a long is that the is*() and to*() routines take ints (says
75 76 * ANSI C), but they use __ct_rune_t instead of int.
76 77 *
77 78 * NOTE: rune_t is not covered by ANSI nor other standards, and should not
78 79 * be instantiated outside of lib/libc/locale. Use wchar_t. wchar_t and
79 80 * rune_t must be the same type. Also, wint_t must be no narrower than
80 81 * wchar_t, and should be able to hold all members of the largest
81 82 * character set plus one extra value (WEOF), and must be at least 16 bits.
82 83 *
83 84 * For compatibility with Solaris, we want to use long in ILP32, and int in
84 85 * LP64. This is due to historical Solaris legacy. (See <wchar.h> for
85 86 * the definition.)
