NAME

       io_uring_prep_renameat - prepare a renameat request

SYNOPSIS

       #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,
                                 unsigned int flags);

DESCRIPTION

       The  io_uring_prep_renameat(3)  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) 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) or rename(2) request. If flags is zero, then
       this call is similar to the renameat(2) system call. See those man pages 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.

NOTES

       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).
