renameat

renameat - rename a file relative to directory file descriptors

#define _ATFILE_SOURCE
#include <stdio.h>
 I int renameat(int  olddirfd , const char * oldpath ,
I              int  newdirfd , const char * newpath );

The R 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 R 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 R AT_FDCWD , then oldpath is interpreted relative to the current working directory of the calling process (like rename(2)). If R oldpath is absolute, then olddirfd is ignored. The interpretation of newpath is as for R oldpath , except that a relative pathname is interpreted relative to the directory referred to by the file descriptor R newdirfd .

On success, R renameat () returns 0. On error, -1 is returned and errno is set to indicate the error.

The same errors that occur for rename(2) can also occur for R renameat (). The following additional errors can occur for R renameat ():

ENOTDIR

R renameat () was added to Linux in kernel 2.6.16.

This system call is non-standard but is proposed for inclusion in a future revision of POSIX.1.

See openat(2) for an explanation of the need for R renameat ().
