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.
