   8             <code class="function">glDeleteBuffers</code> deletes <em class="parameter"><code>n</code></em> buffer objects named by the elements of the array <em class="parameter"><code>buffers</code></em>.
   9             After a buffer object is deleted, it has no contents,
  10             and its name is free for reuse (for example by <a class="citerefentry" href="glGenBuffers.xml"><span class="citerefentry"><span class="refentrytitle">glGenBuffers</span></span></a>).
  11             If a buffer object that is currently bound is deleted, the binding reverts
  12             to 0 (the absence of any buffer object, which reverts to client memory usage).
  13         </p><p>
  14             <code class="function">glDeleteBuffers</code> silently ignores 0's and names that do not correspond to
  15             existing buffer objects.
