NAME

       io_uring_prep_shutdown - prepare a shutdown request

SYNOPSIS

       #include <sys/socket.h>
       #include <liburing.h>

       void io_uring_prep_shutdown(struct io_uring_sqe *sqe,
                                   int sockfd,
                                   int how);

DESCRIPTION

       The io_uring_prep_shutdown(3) function prepares a shutdown
       request. The submission queue entry sqe is setup to use the file
       descriptor sockfd that should be shutdown with the how argument.

       This function prepares an async shutdown(2) request. See that man
       page for details.

RETURN VALUE

       None

ERRORS

       The CQE res 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 -1 on failure and set
       errno to the actual error value, io_uring never uses errno.
       Instead it returns the negated errno directly in the CQE res
       field.
