VFS_FHTOVP(9)	       FreeBSD Kernel Developer's Manual	 VFS_FHTOVP(9)

NAME
     VFS_FHTOVP	-- turn	an NFS filehandle into a vnode

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

     int
     VFS_FHTOVP(struct mount *mp, struct fid *fhp, int flags,
	 struct	vnode **vpp);

DESCRIPTION
     The VFS_FHTOVP() macro is used by the NFS server to turn an NFS filehan-
     dle into a	vnode.

     The arguments it expects are:

     mp	    The	file system.

     fhp    The	filehandle to convert.

     flags  Additional locking flags to	pass through to	vget(9).  File systems
	    are	allowed	to ignore flags	and use	LK_EXCLUSIVE instead.

     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 in-
     formation 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 in-
     ode 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.

RETURN VALUES
     The locked	vnode for the file will	be returned in *vpp.
