The *end parameter to strto[u]l needs to be checked like this:
{
char *end;
unsigned long int ms = strtoul (arg, &end, 10);
if (end && *end == '\0')
timeout = ms;
else
{
argp_error (state,
"--timeout needs a numeric argument (milliseconds)");
return EINVAL;
}
}
(yes it's an example from an argp-based program :-) )
Cheers,
Ben
