I was interested to see that the code makes uses of strtod, and how this
interacts with the minute / hour / day suffix.
$ strace -e trace=clock_nanosleep sleep 3
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=3, tv_nsec=0},
$ strace -e trace=clock_nanosleep sleep 0xas
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=10, tv_nsec=0},
$ strace -e trace=clock_nanosleep sleep 0xam
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=600, tv_nsec=0},
$ strace -e trace=clock_nanosleep sleep 0xad
clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=173, tv_nsec=0},
Here 0xad is interpreted as 173 seconds, not 10 days.
It's a corner case, but should sleep(1) support or tolerate hex input, and if
so, how should it handle the "d" suffix? FWIW I'd just vote to return an error
for hex intervals.
Cheers,
Phil
