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. --- time/Versions | 3 +++ 1 file changed, 3 insertions(+) (limited to 'time/Versions') diff --git a/time/Versions b/time/Versions index df22ac7..69dad1e 100644 --- a/time/Versions +++ b/time/Versions @@ -74,6 +74,9 @@ libc { clock_getres; clock_gettime; clock_settime; clock_getcpuclockid; clock_nanosleep; } + GLIBC_2.34 { + timespec_getres; + } GLIBC_PRIVATE { # same as clock_gettime; used in other libraries __clock_gettime; -- cgit v1.1
