NAME        top

       io_uring_prep_shutdown - prepare a shutdown request

SYNOPSIS        top

#include <sys/socket.h>#include <liburing.h>void io_uring_prep_shutdown(struct io_uring_sqe *sqe,intsockfd,inthow);

DESCRIPTION        top

       Theio_uring_prep_shutdown(3) function prepares a shutdown       request. The submission queue entrysqe is setup to use the file       descriptorsockfd that should be shutdown with thehow argument.       This function prepares an asyncshutdown(2) request. See that man       page for details.

RETURN VALUE        top

       None

ERRORS        top

       The CQEres field will contain the result of the operation. See       the related man page for details on possible values. Note that       where synchronous system calls will return-1on failure and seterrno to the actual error value, io_uring never useserrno.       Instead it returns the negatederrno directly in the CQEres       field.
