-    <title>Description</title>
-
-    <para><function>sd_event_add_child()</function> adds a new child
-    state change event source to an event loop object. The event loop
-    is specified in <parameter>event</parameter>, the event source is
-    returned in the <parameter>source</parameter> parameter. The
-    <parameter>pid</parameter> parameter specifies the process to
-    watch. The <parameter>handler</parameter> must reference a
-    function to call when the process changes state. The handler
-    function will be passed the <parameter>userdata</parameter>
-    pointer, which may be chosen freely by the caller. The handler
-    also receives a pointer to a <structname>const
-    siginfo_t</structname> structure containing the information about
-    the event. The <parameter>options</parameter> parameter determines
-    which state changes will be watched for. It must contain an OR-ed
-    mask of <constant>WEXITED</constant> (watch for the child
-    terminating), <constant>WSTOPPED</constant> (watch for the child
-    being stopped by a signal), and <constant>WCONTINUED</constant>
-    (watch for the child being resumed by a signal). See
-    <citerefentry><refentrytitle>waitid</refentrytitle><manvolnum>2</manvolnum></citerefentry>
-    for further information.</para>
-
-    <para>Only a single handler may be installed for a specific
-    child. The handler is enabled
-    for a single event (<constant>SD_EVENT_ONESHOT</constant>),
-    but this may be
-    changed with
-    <citerefentry><refentrytitle>sd_event_source_set_enabled</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
-    If the handler function returns a negative error code, it will be
-    disabled after the invocation, even if
-    <constant>SD_EVENT_ON</constant> mode is set.
-    </para>
-
-    <para><function>sd_event_source_get_child_pid()</function>
-    retrieves the configured <parameter>pid</parameter> of a child
-    state change event source created previously with
-    <function>sd_event_add_child()</function>. It takes the event
-    source object as the <parameter>source</parameter> parameter and a
-    pointer to <type>pid_t</type> to return the result in.

-    <title>Return Value</title>

-    <para>On success, these functions return 0 or a positive
-    integer. On failure, they return a negative errno-style error
