NAME

       io_uring_sqe_set_data - set user data for submission queue event

SYNOPSIS

       #include <liburing.h>

       void io_uring_sqe_set_data(struct io_uring_sqe *sqe,
                                  void *user_data);

       void io_uring_sqe_set_data64(struct io_uring_sqe *sqe,
                                    __u64 data);

DESCRIPTION

       The io_uring_sqe_set_data(3) function stores a user_data pointer with the submission queue
       entry sqe.

       The io_uring_sqe_set_data64(3) function stores a 64-bit data  value  with  the  submission
       queue entry sqe.

       After  the  caller  has requested a submission queue entry (SQE) with io_uring_get_sqe(3),
       they can associate a data pointer or value with the SQE. Once the completion arrives,  the
       function  io_uring_cqe_get_data(3) or io_uring_cqe_get_data64(3) can be called to retrieve
       the data pointer or value associated with the submitted request.

RETURN VALUE

       None
