glMapBufferRange
public static java.nio.ByteBuffer glMapBufferRange(int target,
long offset,
long length,
int access,
java.nio.ByteBuffer old_buffer)
- 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:
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.
- Parameters:
old_buffer
- A ByteBuffer. If this argument points to the same address and has the same capacity as the new mapping, it will be returned and no new buffer will be created.
- Returns:
- A ByteBuffer representing the mapped buffer memory.
