Two signals are provided for application use: SIGUSR1 and SIGUSR2.  
VxWorks will never use these signals; however, other signals may be used by
VxWorks in the future.

<pre>

int sigInit (void)</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine initializes the signal facilities.  It is usually called from
the system start-up routine <b><i><a href="./usrConfig.html#usrInit">usrInit</a></i>(&nbsp;)</b> in usrConfig, before interrupts are
enabled.

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>int sigqueueInit
    (
    int nQueues
    )</pre>

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine initializes the queued signal facilities. It must
be called before any call to <b><i><a href="./sigLib.html#sigqueue">sigqueue</a></i>(&nbsp;)</b>.  It is usually
called from the system start-up routine <b><i><a href="./usrConfig.html#usrInit">usrInit</a></i>(&nbsp;)</b> in usrConfig,
after <b><i>sysInit</i>(&nbsp;)</b> is called.
<p>
It allocates <i>nQueues</i> buffers to be used by <b><i><a href="./sigLib.html#sigqueue">sigqueue</a></i>(&nbsp;)</b>. A buffer is
used by each call to <b><i><a href="./sigLib.html#sigqueue">sigqueue</a></i>(&nbsp;)</b> and freed when the signal is delivered
(thus if a signal is block, the buffer is unavailable until the signal
is unblocked.)

OK, or ERROR if memory could not be allocated.

</blockquote><h4>SYNOPSIS</h4><blockquote><p>
<pre>int sigemptyset

</blockquote><h4>DESCRIPTION</h4><blockquote><p>
This routine initializes the signal set specified by <i>pSet</i>,
