I have a program that I want to hide the command line arguments on.  This
piece of code worked under SunOS 4.1.x, but doesn't seem to work any
longer.  

    while ((ch = getopt(argc, argv, "U:P:e:a:")) != -1)
      switch (ch) {
      case 'U':
                  strcpy(user, optarg);
                  break;
      case 'P':
                  strcpy(pass, optarg);
                  memset(optarg, ' ', strlen(optarg));
                  break;
      case 'e':
                  strcpy(prog, optarg);
                  args[0] = calloc(strlen(optarg)+1, sizeof(char));
                  strcpy(args[0], optarg);
          break;
      case 'a':
                  args[ac] = calloc(strlen(optarg)+1, sizeof(char));
                  strcpy(args[ac++], optarg);
                  break;
      default:
                  usage();
                  exit(-1);
          break;
      }

Basically, I can specify a username / password on the command line, but
I want to hide the password from a "ps -uxwwa".  Under solaris, if I do
a "ps -ef", the password shows up...the memset seems ineffective.

Is there any other way to hide arguments other than prompting for them
once the program starts, which I did a little later:

    if(!pass[0]) {
                cp = getpass("Password: ");
                if(cp) strcpy(pass, cp);
    }

I believe that the isql program for sybase has the same problem running
under solaris, but we're still on 4.9.2...so perhaps they fixed it.

Thanks,
