 Buffer <char> buf;

 int main()
 {
     buf = 'a';
     buf.put('b');
     char *head = buf.head();
     puts(head);

     char whats_in_there[2] = {0};
     int pos = 0;

     while(buf.available())
     {   
         whats_in_there[pos++] = buf;
     }
     printf("%c %c\n", whats_in_there[0], whats_in_there[1]);
     buf.clear();
