xcb_shm_attach_fd(3)             XCB Requests             xcb_shm_attach_fd(3)

NAME
       xcb_shm_attach_fd - Create a shared memory segment

SYNOPSIS
       #include <xcb/shm.h>

   Request function
       xcb_void_cookie_t xcb_shm_attach_fd(xcb_connection_t *conn,
              xcb_shm_seg_t shmseg, int32_t shm_fd, uint8_t read_only);

REQUEST ARGUMENTS
       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.

DESCRIPTION
       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.

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

ERRORS
       This request does never generate any errors.
