41.Ft int
42.Fn VFS_VGET "struct mount *mp" "ino_t ino" "int flags" "struct vnode **vpp"
43.Sh DESCRIPTION
44The
45.Fn VFS_VGET
46macro converts an inode number into a locked vnode.
47.Pp
48Its arguments are:
49.Bl -tag -width ".Fa flags"
50.It Fa mp
51The file system.
52.It Fa ino

59.Pp
60This is an optional file system entry-point for file systems which have a
61unique id number for every file in the file system.
62It is used
63internally by the UFS file system and also by the NFSv3 server to
64implement the
65.Dv READDIRPLUS
66nfs call.
67.Pp
68If the file system does not support this call, then it should return
69.Er EOPNOTSUPP .
