VOP_OLD_RENAME(9)     DragonFly Kernel Developer's Manual    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]        attempt to remove a directory which is not empty
