# lfc\_rename(3)

rename a LFC file or directory in the name server

## NAME

lfc\_rename - rename a LFC file or directory in the name server

## SYNOPSIS

**#include \<sys/types.h\>**\
 **#include "lfc\_api.h"**

**int lfc\_rename (const char \****oldpath***,** **const char \****newpath***)**

## DESCRIPTION

**lfc\_rename** renames a LFC file or directory in the name server.

*oldpath* and *newpath* must be of the same type, i.e. both regular files or both directories.

If *newpath* exists already, it will be removed before the rename takes place. If *newpath* is a directory, it must be empty.

When renaming a directory, *newpath* must not be a descendant of *oldpath*, i.e. *newpath* must not contain a path prefix that names *oldpath*.

Write permission is required on both parents. If *oldpath* is a directory, write permission is required on it and if *newpath* is an existing directory, write permission is also required on it.

If any of the parents has the sticky bit S\_ISVTX set, either

the effective user ID of the requestor must match the owner ID of the file or

the effective user ID of the requestor must match the owner ID of the directory or

the file must be writable by the requestor or

the requestor must have ADMIN privilege in the Cupv database.

## RETURN VALUE

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, **serrno** is set appropriately.

## ERRORS

- **ENOENT**

  A component of *oldpath* prefix does not exist or *oldpath* or *newpath* is a null pathname.

- **EACCES**

  Search permission is denied on a component of the path prefixes or write permission on the parent directories is denied or *oldpath* is a directory and write permission is denied on *oldpath* or *newpath*.

- **EFAULT**

  *oldpath* or *newpath* is a NULL pointer.

- **EEXIST**

  *newpath* is an existing directory and is not empty or *newpath* is an existing file with replicas.

- **ENOTDIR**

  A component of the path prefixes is not a directory or *oldpath* is a directory and *newpath* is an existing regular file.

- **EISDIR**

  *newpath* is a directory while *oldpath* is a regular file.

- **EINVAL**

  *newpath* is a descendant of *oldpath*.

- **ENAMETOOLONG**

  The length of *oldpath* or *newpath* exceeds **CA\_MAXPATHLEN** or the length of a path component exceeds **CA\_MAXNAMELEN**.

- **SENOSHOST**

  Host unknown.

- **SENOSSERV**

  Service unknown.

- **SECOMERR**

  Communication error.

- **ENSNACT**

  Name server is not running or is being shutdown.
