<pre wrap="">Hello all,
i am currently confused by using the avpops function avp_delete. When i
run avp_delete without the flag-value \g only the last value will be
unset (like an undo). Is this the wanted behaviour?

Hello Sven, <br>
<br>
After looking thru the code it seems that this is the wanted
behaviour (something like sed with /g switch) even in 3.x (master).
<br>
<br>
From the fixup function of avp_delete :<br>
<code><br>
case 'g':<br>
case 'G':<br>
ap->ops|=AVPOPS_FLAG_ALL;<br>
</code><br>
<br>
This flag is sent as the <i>all </i>parameter in destroy_avps in
usr_avp.c method. (The avp's are inserted in memory in reversed
order so it's a Last In First Out type structure)<br>
<br>
Cheers<br>
Marius<br>

EXAMPLE:
$avp(test) = "test"
if( $avp(test)){xlog("L_NOTICE","result1:$avp(test)\n");}
$avp(test) = "nooo";
if( $avp(test)){xlog("L_NOTICE","result2:$avp(test)\n");}
avp_delete("$avp(test)");
if( $avp(test)){xlog("L_NOTICE","result3:$avp(test)\n");}
RESULT:
result1:test
result2:nooo
result3:test
Could anybody helps me to understand that?
thanks in advance,
Sven
