    <para>
     Signals a <parameter>process</parameter> (created using
     <function>proc_open</function>) that it should terminate.
     <function>proc_terminate</function> returns immediately and does not wait
     for the process to terminate.
    </para>
    <para>
     The optional
     <parameter>signal</parameter> is only useful on <acronym>POSIX</acronym>
     operating systems; you may specify a signal to send to the process using
     the <literal>kill(2)</literal> system call.  The default is
     <literal>SIGTERM</literal>.
    </para>

    <para>
     <function>proc_terminate</function> allows you terminate the process and
     continue with other tasks.  You may poll the process (to see if it has
     stopped yet) by using the <function>proc_get_status</function> function.
    </para>

    <para>
     See also <function>proc_open</function>, <function>proc_close</function>,
     and <function>proc_get_status</function>.
