SYNOPSIS

9       #include <sys/socket.h>
10       #include <liburing.h>
11
12       void io_uring_prep_shutdown(struct io_uring_sqe *sqe,
13                                   int sockfd,
14                                   int how);

DESCRIPTION

17       The io_uring_prep_shutdown(3) function prepares a shutdown request. The
18       submission queue entry sqe is setup to use the file  descriptor  sockfd
19       that should be shutdown with the how argument.
20
21       This  function prepares an async shutdown(2) request. See that man page
22       for details.

RETURN VALUE

ERRORS

29       The CQE res field will contain the result of the operation. See the re‐
30       lated man page for details on possible values. Note that where synchro‐
31       nous system calls will return -1 on failure and set errno to the actual
32       error value, io_uring never uses errno.  Instead it returns the negated
33       errno directly in the CQE res field.
