xcb_big_requests_enable - Man Page

#include <xcb/bigreq.h>

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;

conn

The XCB connection to X11.

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.

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.

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.

This request does never generate any errors.
