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