Subject: Re: C23 implications for C libraries
There is a concept called CLOCK_MONOTONIC_RAW (since Linux 2.6.28;
Linux-specific),
May C2x provide TIME_MONOTONIC_RAW in future or can we just implement
TIME_MONOTONIC with
CLOCK_MONOTONIC_RAW on Linux? When implement mesa vulkan driver, it's ask
for CLOCK_MONOTONIC_RAW at
https://gitlab.freedesktop.org/mesa/mesa/-/blob/c6c5949ff70a47c47795fe9161a7514173b5be24/src/vulkan/runtime/vk_device.c#L557
May intention is using C2x timespec_get to replace function
vk_clock_gettime but it's lack of TIME_MONOTONIC_RAW, so I don't know
what's the best way
