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. --- NEWS | 2 ++ 1 file changed, 2 insertions(+) (limited to 'NEWS') diff --git a/NEWS b/NEWS index a5631af..266837b 100644 --- a/NEWS +++ b/NEWS @@ -23,6 +23,8 @@ Major new features: /proc to be mounted.
