Parsing Options using g_option_context_parse in GTK

Hi there,

I am trying to obtain values for my variables through the command line. But the values I get for my variables are returning rubbish. Any idea what I am missing here?

Variables:

Code:

static gchar port[1024];
static gchar localhostname[1024] = "";
static gchar challenge[1024] = "";
static gint verbose = 0;

Entries:

Code:

static GOptionEntry entries[] =
{
  { "host", 'h', 0, G_OPTION_ARG_STRING, &localhostname, "Specify the host to connect to", "HOST" },
  { "port", 'p', 0, G_OPTION_ARG_STRING, &port, "Specify the port to connect to", "PORT" },
  { "challenge", 'c', 0, G_OPTION_ARG_STRING, &challenge, "Specify the challenge when connecting", "CHALLENGE"},
  { "test", 't', 0, G_OPTION_ARG_INT, &test, "Specify the challenge when connecting", "TEST"},
  { "verbose", 'v', 0, G_OPTION_ARG_NONE, &verbose, "Be verbose", NULL },
};

Main:

Code:

    GError *error = NULL;
    GOptionContext *context;
    context = g_option_context_new ("Launch ISR Thin Viewer");
    g_option_context_add_main_entries (context, entries, NULL);
    g_option_context_add_group (context, gtk_get_option_group (TRUE));
    if (!g_option_context_parse (context, &argc, &argv, &error)) {
        g_print ("Option parsing failed: %s\n", error->message);
        exit (1);
    }

    printf ("My port is: %s\n", &port);

Any ideas? The above function returns me: My port is: ��

Found the answer!

Code:

static gchar *port = "";
static gchar *localhostname = "";
static gchar *challenge = "";
