<title>Description</title>
<para>
An attribute list is a zero-terminated list of <type>int32_t</type> key/value pairs or a null pointer. A null
pointer is interpreted as an empty list, whose only member is the terminal zero. For concrete examples of
attribute lists, see the "Examples" section in
<citerefentry><refentrytitle><function>waffle_config</function></refentrytitle><manvolnum>3</manvolnum></citerefentry>.
</para>
<para>
All attribute list functions can be called before waffle has been successfully initialized with
<citerefentry><refentrytitle><function>waffle_init</function></refentrytitle><manvolnum>3</manvolnum></citerefentry>.
</para>
<variablelist>
<varlistentry>
<term><function>waffle_attrib_list_length()</function></term>
<listitem>
<para>
Return the number of key/value pairs in the list.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><function>waffle_attrib_list_get()</function></term>
<listitem>
<para>
Get the <parameter>value</parameter> associated with <parameter>key</parameter>. If the list does not
contain the <parameter>key</parameter>, then <parameter>value</parameter> is not dereferenced.
Return true if and only if the list contains the <parameter>key</parameter>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><function>waffle_attrib_list_get_with_default()</function></term>
<listitem>
<para>
Equivalent to <function>waffle_attrib_list_get()</function> except that if the list does not contain the
<parameter>key</parameter> then <parameter>value</parameter> is set to a <parameter>default_value</parameter>.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><function>waffle_attrib_list_update()</function></term>
<listitem>
<para>
Update the <parameter>value</parameter> associated with <parameter>key</parameter>.
If the list does not contain the <parameter>key</parameter> then the list is not modified.
Return true if and only if the list contains the <parameter>key</parameter>.
</para>

<title>Errors</title>
<para>
All attribute list functions set the error code to <constant>WAFFLE_NO_ERROR</constant> and can be called before
waffle has been successfully initialized with
<citerefentry><refentrytitle><function>waffle_init</function></refentrytitle><manvolnum>3</manvolnum></citerefentry>.
