GETNEWVNODE(9) 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(const char *tag, struct mount *mp, vop_t **vops, struct vnode **vpp);

DESCRIPTION

The getnewvnode() function initializes a new vnode, assigning it the vnode operations passed in vops. The vnode is either freshly allocated, or taken from the head of the free list depending on the number of vnodes already in the system.

The arguments to getnewvnode() are:

tag
The file system type string. This field should only be referenced for debugging or for userland utilities.
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. There are currently no failure conditions - that do not result in a panic.
