NAME

       rfio_rename - rename a file or directory

SYNOPSIS

       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_rename (const char *oldpath, const char *newpath)

DESCRIPTION

       rfio_rename renames a file or directory.

       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 be super-user.

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.

       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.
