NAME

rename - change the name of a file

LIBRARY

Lb libc

SYNOPSIS

In stdio.h Ft int Fn rename const char *from const char *to

DESCRIPTION

The Fn rename system call causes the link named Fa from to be renamed as Fa to . If Fa to exists, it is first removed. Both Fa from and Fa to must be of the same type (that is, both directories or both non-directories), and must reside on the same file system.

The Fn rename system call guarantees that if Fa to already exists, an instance of Fa to will always exist, even if the system should crash in the middle of the operation.

If the final component of Fa from is a symbolic link, the symbolic link is renamed, not the file or directory to which it points.

RETURN VALUES

Rv -std rename

ERRORS

The Fn rename system call will fail and neither of the argument files will be affected if:

Bq Er ENAMETOOLONG

A component of either pathname exceeded 255 characters, or the entire length of either path name exceeded 1023 characters.

Bq Er ENOENT

A component of the Fa from path does not exist, or a path prefix of Fa to does not exist.

Bq Er EACCES

A component of either path prefix denies search permission.

Bq Er EACCES

The requested link requires writing in a directory with a mode that denies write permission.

Bq Er EPERM

The file pointed at by the Fa from argument has its immutable, undeletable or append-only flag set, see the chflags(2) manual page for more information.

Bq Er EPERM

The parent directory of the file pointed at by the Fa from argument has its immutable or append-only flag set.

Bq Er EPERM

The parent directory of the file pointed at by the Fa to argument has its immutable flag set.

Bq Er EPERM

The directory containing Fa from is marked sticky, and neither the containing directory nor Fa from are owned by the effective user ID.

Bq Er EPERM

The file pointed at by the Fa to argument exists, the directory containing Fa to is marked sticky, and neither the containing directory nor Fa to are owned by the effective user ID.

Bq Er ELOOP

Too many symbolic links were encountered in translating either pathname.

Bq Er ENOTDIR

A component of either path prefix is not a directory.

Bq Er ENOTDIR

The Fa from argument is a directory, but Fa to is not a directory.

Bq Er EISDIR

The Fa to argument is a directory, but Fa from is not a directory.

Bq Er EXDEV

The link named by Fa to and the file named by Fa from are on different logical devices (file systems). Note that this error code will not be returned if the implementation permits cross-device links.

Bq Er ENOSPC

The directory in which the entry for the new name is being placed cannot be extended because there is no space left on the file system containing the directory.

Bq Er EDQUOT

The directory in which the entry for the new name is being placed cannot be extended because the user's quota of disk blocks on the file system containing the directory has been exhausted.

Bq Er EIO

An I/O error occurred while making or updating a directory entry.

Bq Er EROFS

The requested link requires writing in a directory on a read-only file system.

Bq Er EFAULT

Path points outside the process's allocated address space.

Bq Er EINVAL

The Fa from argument is a parent directory of Fa to , or an attempt is made to rename `.' or `..'

Bq Er ENOTEMPTY

The Fa to argument is a directory and is not empty.

STANDARDS

The Fn rename system call is expected to conform to St -p1003.1-96 .
