I am quoting this from gtk manual which deals with the callback
function. It clearly states that the second argument is what the
userinputs in the text_entry, which actually I want to catch...

void enter_callback( GtkWidget *widget,
                     GtkWidget *entry )
{
  gchar *entry_text;
  entry_text = gtk_entry_get_text(GTK_ENTRY(entry));
  printf("Entry contents: %s\n", entry_text);
}
