[SR-Users] loop through variables

[Bernhard Suttner]

Hi,

yeah, that looks like a good solution. But I assume that there should be the similar way to use the shm or pseudo variables as a array. Maybe someone else does know more about this way?

Best regards,
Bernhard

Another option is to push the constants into AVP arrays at startup (I 
assume there is some sort of init route at this point, otherwise a 
module init event-route):

    $(avp(s:routers)[0]) = "10.10.10.1";
    $(avp(s:routers)[1]) = "10.10.10.2";
    $(avp(s:routers)[2]) = "10.10.10.3";

You can then iterate through them, using is_avp_set() to check if 
something exists at the current index/array subscript:

    $var(i) = 0;

    while(is_avp_set("$(avp(s:routers)[$var(i)])")) {
       xlog("L_INFO", "Router is: $(avp(s:routers)[$var(i)])\n";
       $var(i) = $var(i) + 1;
    }
