renameat
RENAMEAT(2) Linux Programmer's Manual RENAMEAT(2)NAME
renameat - rename a file relative to directory file descriptors
SYNOPSIS
#include <fcntl.h> /* Definition of AT_* constants */
#include <stdio.h>
int renameat(int olddirfd, const char *oldpath,
int newdirfd, const char *newpath);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
renameat():
Since glibc 2.10: _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10: _ATFILE_SOURCE
DESCRIPTION
The renameat() system call operates in exactly the same way as rename(2), except for the differences described in this manual page.
If the pathname given in oldpath is relative, then it is interpreted relative to the directory referred to by the file descriptor olddirfd
(rather than relative to the current working directory of the calling process, as is done by rename(2) for a relative pathname).
If oldpath is relative and olddirfd is the special value AT_FDCWD, then oldpath is interpreted relative to the current working directory of
the calling process (like rename(2)).
If oldpath is absolute, then olddirfd is ignored.
The interpretation of newpath is as for oldpath, except that a relative pathname is interpreted relative to the directory referred to by
the file descriptor newdirfd.
RETURN VALUE
On success, renameat() returns 0. On error, -1 is returned and errno is set to indicate the error.
ERRORS
The same errors that occur for rename(2) can also occur for renameat(). The following additional errors can occur for renameat():
EBADF olddirfd or newdirfd is not a valid file descriptor.
ENOTDIR
oldpath is relative and olddirfd is a file descriptor referring to a file other than a directory; or similar for newpath and
newdirfd
VERSIONS
renameat() was added to Linux in kernel 2.6.16.
CONFORMING TO
POSIX.1-2008.
NOTES
See openat(2) for an explanation of the need for renameat().
