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_**,**
                               **int** _sockfd_**,**
                               **int** _how_**);**

DESCRIPTION top

   The [io_uring_prep_shutdown(3)](../man3/io%5Furing%5Fprep%5Fshutdown.3.html) 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)](../man2/shutdown.2.html) request. See that man
   page for details.

RETURN VALUE top

   None

ERRORS top

   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](../man3/errno.3.html)_ to the actual error value, io_uring never uses _[errno](../man3/errno.3.html)_.
   Instead it returns the negated _[errno](../man3/errno.3.html)_ directly in the CQE _res_
   field.
