VREF(9)

VREF(9)                  BSD Kernel Developer's Manual                 VREF(9)

NAME
     vref, vrefl — increment the use count for a vnode

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

     void
     vref(struct vnode *vp);

     void
     vrefl(struct vnode *vp);

DESCRIPTION
     Increment the v_usecount field of a vnode.

     vp  the vnode to increment

     Each vnode maintains a reference count of how many parts of the system
     are using the vnode.  This allows the system to detect when a vnode is no
     longer being used and can be safely recycled for a different file.

     Any code in the system which is using a vnode (e.g. during the operation
     of some algorithm or to store in a data structure) should call vref() or
     vrefl().

     vref() locks the vnode interlock while vrefl() expects the interlock to
     already be held.
