io_uring_sqe_set_data - set user data for submission queue event
#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);
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.
