        fd_in:Core.Unix.File_descr.t ->
        ?off_in:int ->

splice ?assume_fd_is_nonblocking ~fd_in ?off_in ~fd_out ?off_out
      ~len flags

see man-page for details.
Raises

Unix_error on Unix-errors.
Invalid_argument if the offsets or length are invalid

Returns the triple

(ret,
      ret_off_in, ret_off_out)

, where ret corresponds to the return value of the system call, ret_off_in to the final input offset, and ret_off_out to the final output offset.
