<p>
<strong>Function</strong> - De-establish a connection to a device.
<h3>SYNOPSIS</h3>

for the named device is decremented.  If this count reaches zero, the close
operation of the device driver is invoked, closing the device.
<h3>NOTES</h3>
<p>
<strong>device_close</strong> will destroy any mapped device windows
obtained through this
device port.
<h3>RETURN VALUES</h3>
