|
||
<p><code class="function">lwres_conf_init()</code>
|
||
creates an empty
|
||
<span class="type">lwres_conf_t</span>
|
||
structure for lightweight resolver context
|
||
<em class="parameter"><code>ctx</code></em>.
|
||
</p>
|
||
<p><code class="function">lwres_conf_clear()</code>
|
||
frees up all the internal memory used by
|
||
that
|
||
<span class="type">lwres_conf_t</span>
|
||
structure in resolver context
|
||
<em class="parameter"><code>ctx</code></em>.
|
||
</p>
|
||
<p><code class="function">lwres_conf_parse()</code>
|
||
opens the file
|
||
<em class="parameter"><code>filename</code></em>
|
||
and parses it to initialise the resolver context
|
||
<em class="parameter"><code>ctx</code></em>'s
|
||
<span class="type">lwres_conf_t</span>
|
||
structure.
|
||
</p>
|
||
<p><code class="function">lwres_conf_print()</code>
|
||
prints the
|
||
<span class="type">lwres_conf_t</span>
|
||
structure for resolver context
|
||
<em class="parameter"><code>ctx</code></em>
|
||
to the

<span class="type">FILE</span>
|
||
<em class="parameter"><code>fp</code></em>.

|
||
<p><code class="function">lwres_conf_parse()</code>
|
||
returns <span class="errorcode">LWRES_R_SUCCESS</span>
|
||
if it successfully read and parsed
|
||
<em class="parameter"><code>filename</code></em>.
|
||
It returns <span class="errorcode">LWRES_R_FAILURE</span>
|
||
if <em class="parameter"><code>filename</code></em>
|
||
could not be opened or contained incorrect
|
||
resolver statements.
|
||
</p>
|
||
<p><code class="function">lwres_conf_print()</code>
|
||
returns <span class="errorcode">LWRES_R_SUCCESS</span>
|
||
unless an error occurred when converting the network addresses to a
|
||
numeric host address string.
|
||
If this happens, the function returns
|
||
<span class="errorcode">LWRES_R_FAILURE</span>.
