xcb_shm_attach3

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.

Overview

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.
