window: TODO: NOT YET DOCUMENTED.

REPLY FIELDS

response_type: The type of this reply, in this case XCB_RANDR_GET_SCREEN_RESOURCES. 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).
timestamp: TODO: NOT YET DOCUMENTED.
config_timestamp: TODO: NOT YET DOCUMENTED.
num_crtcs: TODO: NOT YET DOCUMENTED.
num_outputs: TODO: NOT YET DOCUMENTED.
num_modes: TODO: NOT YET DOCUMENTED.

DESCRIPTION

RETURN VALUE

Returns an xcb_randr_get_screen_resources_cookie_t. Errors have to be handled when calling the reply function xcb_randr_get_screen_resources_reply.

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