title: scrolling content in ncurses box
body: <p>I have a window (created with <code>newwin</code> ) and create box (<code>box (WINDOW *, int, int)</code> ).</p>
  
  <p>I read and write (on FD 0 and 1) under the box, and I get a <code>(char *)</code> from a socket, I wrote this tab in the box.</p>
  
  <p>When I wrote 195 lines, I arrive on the end of the box.</p>
  
  <p>How I can scroll the existing text, so that new text will print at the bottom?</p>
