From: Apollon Oikonomopoulos <apoikos@xxxxxxxxxx>
According to strtoull(3):
[...] Precisely the same holds for strtoull() (with ULLONG_MAX instead
of ULONG_MAX).
Since we are using strtoull(3) and not strtoul(3), the check should be
made against ULLONG_MAX. Note that at least on amd64 ULONG_MAX and
ULLONG_MAX are the same, but this is not guaranteed to be the case for
other architectures as well.
