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, 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.
