<hr><a name="_details"></a><h2>Detailed Description</h2>
This class provides a few alterations to the standard fstream class for dealing with fifo devices.
<p>
In particular, a fifo is assumed to be created via mkfifo and is destroyed when closed. The fifo is a r/w streamable object. fifo streams are presumed unique to posix systems and are generally not portable classes.
