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,
After looking thru the code it seems that this is the wanted
behaviour (something like sed with /g switch) even in 3.x
(master).
From the fixup function of avp_delete :
<code>
case 'g':
case 'G':
ap->ops|=AVPOPS_FLAG_ALL;
</code>
This flag is sent as the all 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)
Cheers
Marius
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
