* glMapBufferARB maps a gl vertex buffer buffer to a ByteBuffer. The oldBuffer argument can be null, in

|
* which case a new ByteBuffer will be created, pointing to the returned memory. If oldBuffer is non-null,
|
|
* it will be returned if it points to the same mapped memory, otherwise a new ByteBuffer is created.
|
|
* That way, an application will normally use glMapBufferARB like this:
|
|
*
|
|
* ByteBuffer mapped_buffer;
|
|
* mapped_buffer = glMapBufferARB(..., ..., ..., null);
|
|
* ...
|
|
* // Another map on the same buffer
|
|
* mapped_buffer = glMapBufferARB(..., ..., ..., mapped_buffer);
|
|
*
|
|
* @param size The size of the buffer area.
|
|
* @param oldBuffer A ByteBuffer. If this argument points to the same address as the new mapping, it will be returned and
|
|
* no new buffer will be created. In that case, size is ignored.
|
|
* @return A ByteBuffer representing the mapped buffer memory.
