51 #define _BSD_CLOCK_T_ int /* clock() */
52 #define _BSD_PTRDIFF_T_ long /* ptr1 - ptr2 */
53 #define _BSD_SIZE_T_ unsigned long /* sizeof() */
54 #define _BSD_SSIZE_T_ long /* byte count or error */
55 #define _BSD_TIME_T_ int /* time() */
61 #define _BSD_VA_LIST_ __va_list /* va_list */
62 #define _BSD_CLOCKID_T_ int /* clockid_t */
63 #define _BSD_TIMER_T_ int /* timer_t */
64 #define _BSD_SUSECONDS_T_ int /* suseconds_t */
65 #define _BSD_USECONDS_T_ unsigned int /* useconds_t */
68 * Types which are fundamental to the implementation and must be used
69 * in more than one standard header although they are only declared in
70 * one (perhaps nonstandard) header are defined here. Standard headers
71 * use _BSD_XXX_T_ without undef'ing it.
73 #define _BSD_CT_RUNE_T_ int /* arg type for ctype funcs */
74 #define _BSD_OFF_T_ long /* file offset */
75 #define _BSD_PID_T_ int /* process [group] */
78 * Runes (wchar_t) is declared to be an ``int'' instead of the more natural
79 * ``unsigned long'' or ``long''. Two things are happening here. It is not
80 * unsigned so that EOF (-1) can be naturally assigned to it and used. Also,
81 * it looks like 10646 will be a 31 bit standard. This means that if your
82 * ints cannot hold 32 bits, you will be in trouble. The reason an int was
83 * chosen over a long is that the is*() and to*() routines take ints (says
84 * ANSI C), but they use _RUNE_T_ instead of int. By changing it here, you
85 * lose a bit of ANSI conformance, but your programs will still work.
87 * Note that _WCHAR_T_ and _RUNE_T_ must be of the same type. When wchar_t
88 * and rune_t are typedef'd, _WCHAR_T_ will be undef'd, but _RUNE_T remains
89 * defined for ctype.h.
91 #define _BSD_WCHAR_T_ int /* wchar_t */
92 #define _BSD_WINT_T_ int /* wint_t */
93 #define _BSD_RUNE_T_ int /* rune_t */
96 * Frequencies of the clock ticks reported by clock() and times(). They
97 * are the same as stathz for bogus historical reasons. They should be
98 * 1e6 because clock() and times() are implemented using getrusage() and
99 * there is no good reason why they should be less accurate. There is
100 * the bad reason that (broken) programs might not like clock_t or
101 * CLOCKS_PER_SEC being ``double'' (``unsigned long'' is not large enough
102 * to hold the required 24 hours worth of ticks if the frequency is
103 * 1000000ul, and ``unsigned long long'' would be nonstandard).

110 * not possible for a machine/compiler combination.
