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.
