.Sh NAME
.Nm vflushbuf
.Nd flush dirty vnode buffers to disk
.Sh SYNOPSIS
.Fd #include <sys/param.h>
.Fd #include <sys/vnode.h>
.Ft void
.Fn vflushbuf "struct vnode *vp" "int sync"
.Sh DESCRIPTION
The
.Fn vflushbuf
function flushes all dirty buffers associated with the vnode
.Fa vp
to the disk.
If the
.Fa sync
argument is zero, writes to the disk will be asynchronous and
.Fn vflushbuf
returns immediately; otherwise, writes will be synchronous and all
disk blocks associated with the vnode will have been properly
synchronized with the in-core buffers upon return.
