# vhold(9)

acquire/release a hold on a vnode

## NAME

**vhold**, **vdrop** – acquire/release a hold on a vnode

## SYNOPSIS

**#include \<sys/param.h\>**

**#include \<sys/vnode.h\>**

*void*\

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

*void*\

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

## DESCRIPTION

The **vhold**() function increments the *v\_holdcnt* of the given vnode. If the vnode has already been added to the free list and is still referenced, it will be removed.

The **vdrop**() function decrements the *v\_holdcnt* of the vnode. If the holdcount is less than or equal to zero prior to calling **vdrop**(), the system will panic. If the vnode is no longer referenced, it will be freed.
