VFS_VGET(9) MidnightBSD Kernel Developer’s Manual 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.
