VOP_VPTOFH(9) BSD Kernel Developer's Manual VOP_VPTOFH(9)NAME
VOP_VPTOFH -- turn a vnode into an NFS filehandle
VOP_VPTOFH(struct vnode *vp, struct fid *fhp);
This is used by the NFS server to create an opaque filehandle which uniquely identifies the file and which can be used by an NFS client to
access the file in the future.
Its arguments are:
vp The vnode to make a filehandle for.
fhp Return parameter for the filehandle.

VFS_FHTOVP(9) BSD Kernel Developer's Manual VFS_FHTOVP(9)NAME
VFS_FHTOVP -- turn an NFS filehandle into a vnode
VFS_FHTOVP(struct mount *mp, struct fid *fhp, struct vnode **vpp);
The VFS_FHTOVP() macro is used by the NFS server to turn an NFS filehandle into a vnode.
The arguments it expects are:
mp The file system.
fhp The filehandle to convert.
vpp Return parameter for the new locked vnode.
The contents of the filehandle are defined by the file system and are not examined by any other part of the system. It should contain enough
information to uniquely identify a file within the file system as well as noticing when a file has been removed and the file system resources
have been reused for a new file. For instance, UFS file system stores the inode number and inode generation counter in its filehandle.
A call to VFS_FHTOVP() should generally be preceded by a call to VFS_CHECKEXP(9) to check if the file is accessible to the client.
The locked vnode for the file will be returned in *vpp.
