From e5ac7bd679de52f70b52b2d0c2135de8d57cba8c Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 17 May 2021 20:55:21 +0000 Subject: Add C2X timespec_getres ISO C2X adds a timespec_getres function alongside the C11 timespec_get, with functionality similar to that of POSIX clock_getres (including allowing a NULL pointer to be passed to the function). Implement this function for glibc, similarly to the implementation of timespec_get. This includes a basic test like that of timespec_get, but no documentation in the manual, given that TIME_UTC and timespec_get aren't documented in the manual at all. The handling of 64-bit time follows that in timespec_get; people maintaining patch series for 64-bit time will need to update them accordingly (to export __timespec_getres64, redirect calls in time.h and run the test for _TIME_BITS=64). Tested for x86_64 and x86, and (previous version; only testcase differs) with build-many-glibcs.py. --- sysdeps/posix/clock_getres.c | 1 + 1 file changed, 1 insertion(+) (limited to 'sysdeps/posix/clock_getres.c') diff --git a/sysdeps/posix/clock_getres.c b/sysdeps/posix/clock_getres.c index 0690ae8fcf..1eb26af6f7 100644 --- a/sysdeps/posix/clock_getres.c +++ b/sysdeps/posix/clock_getres.c @@ -62,6 +62,7 @@ __clock_getres (clockid_t clock_id, struct timespec *res) return retval; } +libc_hidden_def (__clock_getres) versioned_symbol (libc, __clock_getres, clock_getres, GLIBC_2_17); /* clock_getres moved to libc in version 2.17; -- cgit v1.2.3
