VGET(9) BSD Kernel Manual VGET(9)NAMEvget - get a vnode from the free list
SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
int
vget(struct vnode *vp, int flags, struct proc *p);
DESCRIPTION
Get a vnode from the free list and increment its reference count.
Its arguments are:
vp The vnode to remove from the free list.
flags If non-zero, the vnode will also be locked.
p The process responsible for this call.
When not in use, vnodes are kept on a free list. The vnodes still refer-
ence valid files but may be reused to refer to a new file at any time.
Often, these vnodes are also held in caches in the system, such as the
name cache.
When a vnode which is on the free list is used again, for instance if the
vnode was found in the name cache as a result of a call to VOP_LOOKUP(9),
then the new user must call vget() to increment the reference count and
remove it from the free list.
ERRORS
[ENOENT] The vnode vp is in the process of being cleaned out from
the underlying file system.
