I think it would be more true to the strtol() family if in this case (a) we reported -EINVAL (invalid subject sequence) -- but I certainly don't insist on that, (b) and, independently, (b1) we either consumed all of the whitespace sequence *and* the subject sequence (which would be consistent with ERANGE; see test_parse_uint_overflow()), (b2) or we didn't consume anything (not even part of the whitespace sequence). This would be easy to implement and also consistent with the strtol() family's behavior when it sees an invalid subject sequence: "If the subject sequence is empty or does not have the expected form, no conversion is performed; the value of /str/ is stored in the object pointed to by /endptr/, provided that /endptr/ is not a null pointer." But I don't insist on (b) either :) Reviewed-by: Laszlo Ersek <ler...@redhat.com>
