any clue why this isn't retrieving the contents of the temp file


Question Deck::create_question(WINDOW* menu_win, std::ostream &os ,std::istream &in ){
      
      char default_editor[20000] = "vi ";
      char * editor;
      char tmp[4096];
      char path[] = "/tmp/fileXXXXXX";
      int fd;
      fd = mkstemp(path);
      editor = getenv("EDITOR");
      if (editor == NULL){
	 editor  = default_editor;
      }

      strcat(editor, path);
      char quest_prompt[] = "Edit Your Question";
....
      std::string input_q, input_a;
      while( ( c=wgetch(quest_win) ) ){
	 if ( (c == 10) ){
	    def_prog_mode();
	    endwin();
	    system(editor);
	    reset_prog_mode();
	     __gnu_cxx::stdio_filebuf< char>  tmpfile_buf(fd, std::ios::binary|std::ios::app);
	     std::istream is(&tmpfile_buf);
	     is.seekg(0, std::ios::beg);
	     while(is){
		is.read( tmp, 4096);
		std::cerr << "What did we read" << tmp << std::endl;
		input_q = tmp;
	     }
	     tmpfile_buf.close();
	     break;
	 }
