glGetBufferSubData: man2/glGetBufferSubData.xml
glGetBufferSubData returns some or all of the data from the buffer object currently bound to target. Data starting at byte offset offset and extending for size bytes is copied from the data store to the memory pointed to by data. An error is thrown if the buffer object is currently mapped, or if offset and size together define a range beyond the bounds of the buffer object's data store.
If an error is generated, no change is made to the contents of data. glGetBufferSubData is available only if the GL version is 1.5 or greater. Targets GL_PIXEL_PACK_BUFFER and GL_PIXEL_UNPACK_BUFFER are available only if the GL version is 2.1 or greater.
