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, 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.

     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.

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