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:

ByteBuffer mapped_buffer; mapped_buffer = glMapBufferRange(..., ..., ..., ..., null); ... // Another map on the same buffer mapped_buffer = glMapBufferRange(..., ..., ..., ..., mapped_buffer);

Only ByteBuffers returned from this method are to be passed as the old_buffer argument. User-created ByteBuffers cannot be reused.
