So, how would the following text be for the man page?
ERRORS
EFAULT t points outside your accessible address space. On sysâ
tems where the C library time() wrapper function invokes
an implementation provided by the vdso(7) (so that there
is no trap into the kernel), an invalid address may
instead trigger a SIGSEGV signal.
Thanks,
