GETNEWVNODE(9) BSD Kernel Developer's Manual GETNEWVNODE(9)NAME
getnewvnode -- get a new vnode
SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
#include <sys/mount.h>
int
getnewvnode(const char *tag, struct mount *mp, vop_t **vops, struct vnode **vpp);
DESCRIPTION
The getnewvnode() function initializes a new vnode, assigning it the vnode operations passed in vops. The vnode is either freshly allocated,
or taken from the head of the free list depending on the number of vnodes already in the system.
The arguments to getnewvnode() are:
tag The file system type string. This field should only be referenced for debugging or for userland utilities.
mp The mount point to add the new vnode to.
vops The vnode operations to assign to the new vnode.
vpp Points to the new vnode upon successful completion.
RETURN VALUES
getnewvnode() returns 0 on success. There are currently no failure conditions - that do not result in a panic.

VFS_VGET(9) BSD Kernel Developer's Manual VFS_VGET(9)NAME
VFS_VGET -- convert an inode number to a vnode
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
#include <sys/vnode.h>
int
VFS_VGET(struct mount *mp, ino_t ino, int flags, struct vnode **vpp);
DESCRIPTION
The VFS_VGET() looks up or creates a vnode from a (mount, inode#) tuple.
Its arguments are:
mp The mount point.
ino The inode representing the file. This is a unique number assigned by the file system when vnodes are first created.
flags Additional locking flags to pass through to vget(9).
vpp Return parameter for the vnode.
This is an optional file system entry-point for file systems mainly intended for NFS server use, but many file systems use it internally in
VOP_LOOKUP(9) and similar.
If the file system does not support this call, then it should return EOPNOTSUPP.
Please see ffs_vget() in sys/ufs/ffs/ffs_vfsops.c for the canonical example.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
