6. Generic Operating System Services
</H1>

<P>
The modules described in this chapter provide interfaces to operating
system features that are available on (almost) all operating systems,
such as files and a clock.  The interfaces are generally modeled
after the <span class="Unix">Unix</span> or C interfaces, but they are available on most
other systems as well.  Here's an overview:
