   io_uring_prep_renameat - prepare a renameat request

SYNOPSIS top

   **#include <fcntl.h>**
   **#include <stdio.h>**
   **#include <liburing.h>**

   **void io_uring_prep_renameat(struct io_uring_sqe ***_sqe_**,**
                               **int** _olddirfd_**,**
                               **const char ***_oldpath_**,**
                               **int** _newdirfd_**,**
                               **const char ***_newpath_**,**
                               **unsigned int** _flags_**);**

   **void io_uring_prep_rename(struct io_uring_sqe ***_sqe_**,**
                             **const char ***_oldpath_**,**
                             **const char ***_newpath_**);**

DESCRIPTION top

   The [io_uring_prep_renameat(3)](../man3/io%5Furing%5Fprep%5Frenameat.3.html) function prepares a renameat
   request. The submission queue entry _sqe_ is setup to use the old
   directory file descriptor pointed to by _olddirfd_ and old path
   pointed to by _oldpath_ with the new directory file descriptor
   pointed to by _newdirfd_ and the new path pointed to by _newpath_ and
   using the specified flags in _flags_.

   The [io_uring_prep_rename(3)](../man3/io%5Furing%5Fprep%5Frename.3.html) function prepares a rename request.
   The submission queue entry _sqe_ is setup to use the old path
   pointed to by _oldpath_ with the new path pointed to by _newpath_,
   both relative to the current working directory and using the
   specified flags in _flags_.

   These functions prepare an async [renameat2(2)](../man2/renameat2.2.html) or [rename(2)](../man2/rename.2.html)
   request. If _flags_ is zero, then this call is similar to the
   [renameat(2)](../man2/renameat.2.html) system call. See those man pages 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.

NOTES top

   As with any request that passes in data in a struct, that data
   must remain valid until the request has been successfully
   submitted. It need not remain valid until completion. Once a
   request has been submitted, the in-kernel state is stable. Very
   early kernels (5.4 and earlier) required state to be stable until
   the completion occurred. Applications can test for this behavior
   by inspecting the **IORING_FEAT_SUBMIT_STABLE** flag passed back from
   [io_uring_queue_init_params(3)](../man3/io%5Furing%5Fqueue%5Finit%5Fparams.3.html).
