Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml

<title>Description</title>
|
|
|
|
<para><function>sd_bus_message_get_cookie()</function> returns the
|
|
transaction cookie of a message. The cookie uniquely identifies a
|
|
message within each bus peer, but is not globally unique. It is
|
|
assigned when a message is sent.</para>
|
|
|
|
<para><function>sd_bus_message_get_reply_cookie()</function>
|
|
returns the transaction cookie of the message the specified
|
|
message is a response to. When a reply message is generated for a
|
|
method call message, its cookie is copied over into this field.
|
|
Note that while every message that is transferred is identified by
|
|
a cookie, only response messages carry a reply cookie
|
|
field.</para>
|
|
|
|
<para>Both functions take a message object as first parameter and
|
|
a place to store the 64-bit cookie in.</para>

<title>Return Value</title>
|
|
|
|
<para>On success, these calls return 0 or a positive integer. On
|
|
failure, these calls return a negative errno-style error
|
|
code.</para>
|
|
|
|
<para>On success, the cookie/reply cookie is returned in the
|
|
specified 64-bit unsigned integer variable.</para>

<para>Returned errors may indicate the following problems:</para>

<variablelist>

<varlistentry>
|

<term><constant>-EINVAL</constant></term>

<term><constant>-ENODATA</constant></term>
|

|
|
<listitem><para>No cookie has been assigned to this message.
|
|
This either indicates that the message has not been sent yet
|
|
and hence has no cookie assigned, or that the message is not a
|
|
method response message and hence carries a reply cookie
|
|
field.</para></listitem>
