X Version 11                                      libxcb 1.17.0                                xcb_shm_attach(3)

       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.

       This request does never generate any errors.

       xcb_shm_attach - Attach a System V shared memory segment.

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.

       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.
