I think there's an example in the source? Anyway, what worked for me
(ORBit 1.15 or so):

  /* TODO Could use ORBit_string_to_CosNaming_Name() to make names
easier,
    and possibly the lname functions from ORBIt */

    case 'f':

      strcpy(infile_name, optarg);

      if (infile == NULL) {

      size = fread(ns_ior_string, 1, MAX_IOR_LEN, infile);
      fclose(infile);
      // TODO check that IOR was not truncated
      /* Ensure that the ior string is terminated correctly */
      ns_ior_string[--size] = '\0'; 
      use_ns = 1;
      break;

  int orb_argc = 2;
