REPLY FIELDS
- response_type
- The type of this reply, in this case XCB_ALLOC_COLOR_PLANES. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other.
- sequence
- The sequence number of the last request processed by the X11 server.
- length
- The length of the reply, in words (a word is 4 bytes).
- pixels_len
- TODO: NOT YET DOCUMENTED.
- red_mask
- TODO: NOT YET DOCUMENTED.
- green_mask
- TODO: NOT YET DOCUMENTED.
- blue_mask
- TODO: NOT YET DOCUMENTED.
DESCRIPTION
RETURN VALUE
Returns an xcb_alloc_color_planes_cookie_t. Errors have to be handled when calling the reply function xcb_alloc_color_planes_reply.If you want to handle errors in the event loop instead, use xcb_alloc_color_planes_unchecked. See xcb-requests(3) for details.
ERRORS
This request does never generate any errors.SEE ALSO
