xcb_shm_attach(3) XCB Requests xcb_shm_attach(3)

NAME

xcb_shm_attach - Attach a System V shared memory segment.

SYNOPSIS

#include <xcb/shm.h>

Request function

xcb_void_cookie_t xcb_shm_attach(xcb_connection_t *conn,
xcb_shm_seg_t shmseg, uint32_t shmid, uint8_t read_only);

REQUEST ARGUMENTS

conn The XCB connection to X11.

shmseg A shared memory segment ID created with xcb_generate_id().

shmid The System V shared memory segment the server should map.

read_only True if the segment shall be mapped read only by the X11
server, otherwise false.

DESCRIPTION

Attach a System V shared memory segment to the server. This will
fail unless the server has permission to map the segment. The client
may destroy the segment as soon as it receives a XCB_SHM_COMPLETION
event with the shmseg value in this request and with the appropriate
serial number.

RETURN VALUE

Returns an xcb_void_cookie_t. Errors (if any) have to be handled in
the event loop.

If you want to handle errors directly with xcb_request_check instead,
use xcb_shm_attach_checked. See xcb-requests(3) for details.

ERRORS

This request does never generate any errors.
