length
The length of the reply, in words (a word is 4 bytes).
framebuffer_handle_low
TODO: NOT YET DOCUMENTED.
framebuffer_handle_high
TODO: NOT YET DOCUMENTED.
framebuffer_origin_offset
TODO: NOT YET DOCUMENTED.

Return Value

Returns an xcb_xf86dri_get_device_info_cookie_t. Errors have to be handled when calling the reply function xcb_xf86dri_get_device_info_reply.

If you want to handle errors in the event loop instead, use xcb_xf86dri_get_device_info_unchecked. See xcb-requests(3) for details.

Errors
