VOP_OLD_RENAME(9)

NAME
VOP_OLD_RENAME - rename a file

SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
int
VOP_OLD_RENAME(struct vnode *fdvp, struct vnode *fvp, struct componentname *fcnp, struct vnode *tdvp, struct vnode *tvp, struct componentname *tcnp);

DESCRIPTION
This renames a file and possibly changes its parent directory. If the destination object exists, it will be removed first.

Its arguments are:

fdvp
    the vnode of the old parent directory

fvp the vnode of the file to be renamed

fcnp
    pathname information about the file's current name

tdvp
    the vnode of the new parent directory

tvp the vnode of the target file (if it exists)

tcnp
    pathname information about the file's new name

LOCKS
The source directory and file are unlocked but are expected to have their ref count bumped on entry. The VOP routine is expected to vrele() both prior to returning.

The destination directory and file are locked as well as having their ref count bumped. The VOP routine is expected to vput() both prior to returning.

ERRORS

[EPERM]
    the file is immutable

[EXDEV]
    cross device move

[EINVAL]
    illegal directory rename

[ENOTDIR]
    attempt to rename a directory to a file or vice versa

[ENOTEMPTY]
