{
  int ich;

  while ((ich = (argc, argv, "abc"))) {
    switch (ich) {
      case 'a': /* Flags/Code when -a is specified */
        printf("test a");
        break;
      case 'b': /* Flags/Code when -b is specified */
                /* The argument passed in with b is specified */
		/* by optarg */
        printf("test b");
        break;
      case 'c': /* Flags/Code when -c is specified */
        printf("test c");
        break;
      default: /* Code when there are no parameters  */
        printf("test none");
        break;
    }
  }
    return 1;
}

What do you mean by executing URLs?

while ((ich = (argc, argv, "abc")))

No way, what should this line do?

[Muk108]

i dont know, im trying to figure out how to make an aplication that i can execute something like this "c:\folder\app -h host.dns.com -u username -p password" and it will update my dns.

But what do you mean by executing an URL?

[Muk108]

i need to be able to send a http request though tcp in my program, like you do in telnet with "GET HTTP/1.0" i need to be able to send that through the command line program im making.

Can't you simply write an input file for telnet?

[Muk108]
