   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.
