    Is getopt() and its companions, commonly found in GNU libc and other
    Unices libc, part of the C standard?

    Another doubt: I have a switch inside a while loop; is there a way to
    break out of the loop from the switch without using goto? I mean:

    start:
    while(chr = fgetc(inputfile))
    {
     switch(chr)
    {
     case 'a': case 'b':
      do_one_stuff(chr);
      break;
     case 'c': case 'd':
      do_some_other_stuff(chr);
      break;
     case 'e': case 'f':
      do_stuff(chr);
      break;
     default:
       goto start;
    } /* end switch */
    do_even_more_stuff_here();
    } /* end while */

    Is there a way to get out of the while (i.e., skipping the
    "do_even_more_stuff_here();" part) without using this goto?

    Thank in advance.
