NAMEvcount, count_dev — get total number of references to a device
SYNOPSIS#include < sys/param.h>
#include < sys/time.h>
#include < sys/conf.h>
#include < sys/vnode.h>
vcount( struct vnode *vp);
count_dev( struct cdev *dev);
DESCRIPTIONvcount() 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 struct cdev rather than a struct vnode pointer as an argument.
RETURN VALUESvcount() and count_dev() both return the number of references to the device.
