7. Optional Operating System Services
</H1>

<P>
The modules described in this chapter provide interfaces to operating
system features that are available on selected operating systems only.
The interfaces are generally modeled after the <span class="Unix">Unix</span> or C
interfaces but they are available on some other systems as well
(e.g. Windows or NT).  Here's an overview:
