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
