# NAME

`vrele` — decrement the use count for a vnode

# SYNOPSIS

`#include <sys/param.h>`
`#include <sys/vnode.h>`

int
`vrele`(struct vnode *vp);

# DESCRIPTION

Decrement the v_usecount field of the vnode specified by vp.

Any code in the system which uses a vnode should call `vrele`() when it is finished with the vnode. If the v_usecount field of the vnode reaches zero, the vnode will be placed on the free list.

# RETURN VALUES

`vrele`() returns 0 if it can guarantee that it did not sleep.
