SYNOPSIS


.In sys/param.h
.In sys/time.h
.In sys/conf.h
.In sys/vnode.h int vcount struct vnode *vp int count_dev struct cdev *dev

DESCRIPTION

vcount is used to get the number of references to a particular device. It allows for the fact that multiple vnodes may reference the same device. count_dev does the same thing as vcount, but takes a
.Vt struct cdev rather than a
.Vt struct vnode pointer as an argument.

RETURN VALUES

vcount and count_dev both return the number of references to the device.
