Hi Fabio,
this is what I would try:
while ((c = getopt(argc, argv, "n:t:v")) != -1) {
switch (c)
{
case 'n':
n_flag = (int)strtoul(optarg, NULL, 0);
break;
case 't':
t_flag = (int)strtoul(optarg, NULL, 0);
break;
case 'v':
v_flag = true;
break;
default:
return -1;
}
}
It's not tested though, but hopefully points you to the right direction.
