Not really.

"strto[u]l(arg, &endp, 10)" parses arg as a decimal and moves "char *endp"
to point at where the number ended, so you can tell things like:

 - return value of 0 with (arg == endp) being "an empty input, the user
   did not necessarily meant zero"; or

 - (*endp != '\0') being "some garbage after the number".
