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