75 * The rune type above is declared to be an ``int'' instead of the more natural
76 * ``unsigned long'' or ``long''. Two things are happening here. It is not
77 * unsigned so that EOF (-1) can be naturally assigned to it and used. Also,
78 * it looks like 10646 will be a 31 bit standard. This means that if your
79 * ints cannot hold 32 bits, you will be in trouble. The reason an int was
80 * chosen over a long is that the is*() and to*() routines take ints (says
81 * ANSI C), but they use _BSD_CT_RUNE_T_ instead of int. By changing it
82 * here, you lose a bit of ANSI conformance, but your programs will still
85 * NOTE: rune_t is not covered by ANSI nor other standards, and should not
86 * be instantiated outside of lib/libc/locale. Use wchar_t. wchar_t and
87 * rune_t must be the same type. Also wint_t must be no narrower than
88 * wchar_t, and should also be able to hold all members of the largest
89 * character set plus one extra value (WEOF). wint_t must be at least 16 bits.
93 * Frequencies of the clock ticks reported by clock() and times(). They
94 * are the same as stathz for bogus historical reasons. They should be
95 * 1e6 because clock() and times() are implemented using getrusage() and
96 * there is no good reason why they should be less accurate. There is
97 * the bad reason that (broken) programs might not like clock_t or
98 * CLOCKS_PER_SEC being ``double'' (``unsigned long'' is not large enough
99 * to hold the required 24 hours worth of ticks if the frequency is
100 * 1000000ul, and ``unsigned long long'' would be nonstandard).
