X Version 11                                      libxcb 1.17.0                             xcb_shm_attach_fd(3)

       Create  a shared memory segment.  The file descriptor will be mapped at offset zero, and the size will be
       obtained using fstat().  A zero size will result in a Value error.

       This request does never generate any errors.

       xcb_shm_attach_fd - Create a shared memory segment

conn      The XCB connection to X11.

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

       shm_fd    The file descriptor the server should mmap().

       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_fd_checked.  See
       xcb-requests(3) for details.
