vfs_vget(9)

NAME

VFS_VGET - convert an inode number to a vnode

SYNOPSIS

#include <sys/param.h>
#include <sys/mount.h>
#include <sys/vnode.h>
int
VFS_VGET(struct mount *mp,  ino_t  ino,  int  flags,  struct
vnode **vpp);

DESCRIPTION

The VFS_VGET() looks up or creates a vnode from a (mount,

inode#) tupple.

Its arguments are:

mp The mount point.

ino The inode representing the file. This is a

unique number

assigned by the file system when vnodes are first

created.

flags Additional locking flags to pass through to

vget(9).

vpp Return parameter for the vnode.

This is an optional file system entry-point for file systems

mainly
intended for NFS server use, but many file systems use it

internally in
VOP_LOOKUP(9) and similar.

If the file system does not support this call, then it

should return
EOPNOTSUPP.

Please see ffs_vget() in sys/ufs/ffs/ffs_vfsops.c for the

canonical example.
