# vcount(9)

get total number of references to a device

## NAME

**vcount**, **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\>**

*int*\

**vcount**(*struct vnode \*vp*);

*int*\

**count\_dev**(*dev\_t 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 *dev\_t* rather than a *struct vnode* pointer as an argument.

## RETURN VALUES

**vcount**() and **count\_dev**() both return the number of references to the device.
