REPLY FIELDS

response_type: The type of this reply, in this case XCB_GET_IMAGE. 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.

depth: TODO: NOT YET DOCUMENTED.
visual: TODO: NOT YET DOCUMENTED.

DESCRIPTION

RETURN VALUE

Returns an xcb_get_image_cookie_t. Errors have to be handled when calling the reply function xcb_get_image_reply.

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

ERRORS

This request does never generate any errors.
