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 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.

RETURN VALUES

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