Hello,<br>
<br>
yes, the return codes are interpreted in a special way, see:<br>
<br>
- <a class="moz-txt-link-freetext" href="http://www.kamailio.org/wiki/cookbooks/devel/core#return">http://www.kamailio.org/wiki/cookbooks/devel/core#return</a><br>
<br>
Same applies for the functions exported by the modules.<br>
<br>
Cheers,<br>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just a sanity check, really. Does Kamailio
consider negative response codes to be false? For example,
should the following log execute?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier
New"">if (!foo()) { # Returns -2<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier
New""> x_log(“Foo is false”);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier
New"">}<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier
New""><o:p> </o:p></span></p>
<p class="MsoNormal">The reason for asking here is that I’m
implementing flood protection using pike, based off the
kamailio.cfg that ships with v4.3. The logic is thus:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-family:"Courier
New"">if (!pike_check_req()) {<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier
New""> # Do blocking<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier
New"">}<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However pike_check_req only returns -1 or
-2 in the case of failure, never 0. The blocking code is,
thus, never executed. Changing to explicitly check for != 1
works correctly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Am I missing something here or is the
example kamailio.cfg incorrect?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Cheers<o:p></o:p></p>
