<para><function>lwres_conf_init()</function>
creates an empty

structure for lightweight resolver context
<parameter>ctx</parameter>.
</para>
<para><function>lwres_conf_clear()</function>
frees up all the internal memory used by

<para><function>lwres_conf_parse()</function>
opens the file

structure.
</para>
<para><function>lwres_conf_print()</function>
prints the

<para><function>lwres_conf_print()</function>
returns <errorcode>LWRES_R_SUCCESS</errorcode>
