VFS_VGET(9) Kernel Developer's Manual VFS_VGET(9)

NAME

VFS_VGETconvert 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 () looks up or creates a vnode from a (mount, inode#) tuple.

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 () in sys/ufs/ffs/ffs_vfsops.c for the canonical example.
