.SH SYNOPSIS
.B #include <sys/types.h>
.br
\fB#include "Cns_api.h"\fR
.sp
.BI "int Cns_rename (const char *" oldpath ,
.BI "const char *" newpath )
.SH DESCRIPTION
.B Cns_rename
renames a CASTOR file or directory in the name server.
.LP
.I oldpath
and
.I newpath
must be of the same type, i.e. both regular files or both directories.
.LP
If
.I newpath
exists already, it will be removed before the rename takes place. If
.I newpath
is a directory, it must be empty.
.LP
When renaming a directory,
.I newpath
must not be a descendant of
.IR oldpath ,
i.e.
.I newpath
must not contain a path prefix that names
.IR oldpath .
.LP
Write permission is required on both parents. If
.I oldpath
is a directory, write permission is required on it and if
.I newpath
is an existing directory, write permission is also required on it.
.LP
If any of the parents has the sticky bit S_ISVTX set, either
.RS
.LP
the effective user ID of the requestor must match the owner ID of the file or
.LP
the effective user ID of the requestor must match the owner ID of the directory or
.LP
the file must be writable by the requestor or
.LP
the requestor must have ADMIN privilege in the Cupv database.
