Reply datastructure

typedef struct xcb_big_requests_enable_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint32_t maximum_request_length;
} xcb_big_requests_enable_reply_t;

Reply function

xcb_big_requests_enable_reply_t *xcb_big_requests_enable_reply(xcb_connection_t *conn, xcb_big_requests_enable_cookie_t cookie, xcb_generic_error_t **e);

REQUEST ARGUMENTS

conn: The XCB connection to X11.

REPLY FIELDS

response_type: The type of this reply, in this case XCB_BIG_REQUESTS_ENABLE. 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).
maximum_request_length: The maximum length of requests supported by the server, in 4-byte units.

DESCRIPTION

This enables the BIG-REQUESTS extension, which allows for requests larger than 262140 bytes in length. When enabled, if the 16-bit length field is zero, it is immediately followed by a 32-bit length field specifying the length of the request in 4-byte units.

RETURN VALUE

Returns an xcb_big_requests_enable_cookie_t. Errors have to be handled when calling the reply function xcb_big_requests_enable_reply.

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

ERRORS

This request does never generate any errors.
