NAME    [Toc]    [Back]

     VFS_FHTOVP -- turn an NFS filehandle into a vnode

SYNOPSIS    [Toc]    [Back]

     #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    [Toc]    [Back]

     This is used by the NFS server to turn an NFS filehandle into a vnode.

     Its arguments 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 this function should generally be preceded by a call to
     VFS_CHECKEXP(9) to check if the file is accessible to the client.

RETURN VALUES    [Toc]    [Back]

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