GETNEWVNODE(9) FreeBSD Kernel Developer's Manual GETNEWVNODE(9)
NAME
getnewvnode - get a new vnode
SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
#include <sys/mount.h>
int
getnewvnode(enum vtagtype tag, struct mount *mp, const struct vops *vops,
struct vnode **vpp);
DESCRIPTION
The getnewvnode() function initializes a new vnode, assigning it the
vnode operations passed in vops. It will have its v_tag field set to tag
and be placed in the mount queue for the mount point represented by mp.
The vnode is either freshly allocated, taken from the free list or taken
from the hold list. If there are no vnodes on the free list, half the
time a vnode referencing buffers will be taken from the hold list,
otherwise it will be freshly allocated.
The arguments to getnewvnode() are:
tag The file system type.
mp The mount point to add the new vnode to.
vops The vnode operations to assign to the new vnode.
vpp Points to the new vnode upon successful completion.
RETURN VALUES
getnewvnode() returns 0 on success, or ENFILE if the vnode table is full.
