typedef struct xcb_big_requests_enable_reply_t {
uint8_t response_type;

uint32_t length;
uint32_t maximum_request_length;
} xcb_big_requests_enable_reply_t;

Reply function

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.
