[Click] fopen , fread

[Vandorpe Wouter]

Hello,

thx for the replay's, it helped me in this way,
i've solved the problem as follow,

In element with handler while configuring:
     if (router()->attachment("rtpQos"))
	return errh->error("router has more than one rtpQos element");
     router()->set_attachment("rtpQos", this);
and I made a function in rtpQos:
int rtpQos::return_Loss_percentage()
{
return _Loss();//_Loss has value of handler i wanted to read
}

In the element rtpQosFeedback (to send rtp with loss of packets)

 if(rtpQos* rq = (rtpQos*) router()->attachment("rtpQos")){
        _Loss = rq -> return_Loss_percentage();
 }else{
        _Loss = 0;
        errorhandler();
 }

problem solved :)

grtz,
Wouter Vandorpe

Hi Wouter,

Have a look at <clickdir>/elements/standard/unqueue2 and 
<clickdir>/elements/standard/aqm/red
 
In short, you gain a pointer to your rtpQos element, this can be done
using a configuration option or using upstream or downstream element
finder routines. Once you have the pointer you can call your handler
funtions.

Regards
