After the caller has received a completion queue entry (CQE) with io_uring_wait_cqe(), he can call he io_uring_cqe_get_data() function to retrieve the .I user_data value. This requires that .I user_data has been set earlier with the function io_uring_sqe_set_data(). .SH RETURN VALUE If the .I user_data value has been set before submitting the request, it will be returned. Otherwise the functions returns NULL. .SH SEE ALSO .BR io_uring_get_sqe (3), io_uring_sqe_set_data (3), io_uring_sqe_submit(3)
