<h4>glMapBufferRangeEXT</h4>

java.nio.ByteBuffer&nbsp;old_buffer)</pre>
<div class="block">glMapBufferRange maps a GL buffer object range to a ByteBuffer. The old_buffer argument can be null,
in which case a new ByteBuffer will be created, pointing to the returned memory. If old_buffer is non-null,
it will be returned if it points to the same mapped memory and has the same capacity as the buffer object,
otherwise a new ByteBuffer is created. That way, an application will normally use glMapBufferRange like this:
<p/>
ByteBuffer mapped_buffer; mapped_buffer = glMapBufferRange(..., ..., ..., ..., null); ... // Another map on the same buffer mapped_buffer = glMapBufferRange(..., ..., ..., ..., mapped_buffer);
<p/>
Only ByteBuffers returned from this method are to be passed as the old_buffer argument. User-created ByteBuffers cannot be reused.
<p></div>
