From f4d6ef2d417e0fc10a159ab64827f837c9a3be84 Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Wed, 28 Nov 2018 22:49:30 +0100 Subject: [PATCH] time.h: Introduce Linux-specific CLOCK id values - Add CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_RAW, CLOCK_MONOTONIC_COARSE and CLOCK_BOOTTIME - Guard new values with __GNU_VISIBLE - Add CLOCK_REALTIME_COARSE as (clockid_t) 0 for simplicity (It allows to have all values < 8 and so be used as array index into an array of clocks) - Fix macro bracketing Signed-off-by: Corinna Vinschen --- newlib/libc/include/time.h | 22 ++++++++++++++++++---- 1 file changed, 18 insertions(+), 4 deletions(-) diff --git a/newlib/libc/include/time.h b/newlib/libc/include/time.h index a2efcc15e..bd35d0e02 100644 --- a/newlib/libc/include/time.h +++ b/newlib/libc/include/time.h @@ -251,7 +251,11 @@ extern "C" { /* Manifest Constants, P1003.1b-1993, p. 262 */ -#define CLOCK_REALTIME (clockid_t)1 +#if __GNU_VISIBLE +#define CLOCK_REALTIME_COARSE ((clockid_t) 0) +#endif + +#define CLOCK_REALTIME ((clockid_t) 1) /* Flag indicating time is "absolute" with respect to the clock associated with a time. */ @@ -266,7 +270,7 @@ extern "C" { the identifier of the CPU_time clock associated with the PROCESS making the function call. */ -#define CLOCK_PROCESS_CPUTIME_ID (clockid_t)2 +#define CLOCK_PROCESS_CPUTIME_ID ((clockid_t) 2) #endif @@ -276,7 +280,7 @@ extern "C" { the identifier of the CPU_time clock associated with the THREAD making the function call. */ -#define CLOCK_THREAD_CPUTIME_ID (clockid_t)3 +#define CLOCK_THREAD_CPUTIME_ID ((clockid_t) 3) #endif @@ -286,7 +290,17 @@ extern "C" { * as a clock whose value cannot be set via clock_settime() and which * cannot have backward clock jumps. */ -#define CLOCK_MONOTONIC (clockid_t)4 +#define CLOCK_MONOTONIC ((clockid_t) 4) + +#if __GNU_VISIBLE + +#define CLOCK_MONOTONIC_RAW ((clockid_t) 5) + +#define CLOCK_MONOTONIC_COARSE ((clockid_t) 6) + +#define CLOCK_BOOTTIME ((clockid_t) 7) + +#endif #endif
