NAME¶

VOP_RENAME — rename a file

SYNOPSIS¶

#include <sys/param.h>
#include <sys/vnode.h>

int
VOP_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(9) 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(9) both prior to returning.

ERRORS¶

[EPERM]

The file is immutable.

[EXDEV]

It is not possible to rename a file between different file systems.
