[Users] Variables

[Douglas Garstang]

So... using an example I found, if I have something like this...

avp_printf("i:20", "This is a $rm request with the call-id $hdr(call-id)");

how do I print the value "i:20"? or whatever the heck that means....?

Hi Doug,

use avp_printf() or avp_subst() to process the content of an avp - this 
function covers the assigning operation.

I'm sending a lot of info to syslog with xlog(), and with multiple threads (processes?) and multiple calls running, all the output is out of sequence. As a result, I'd like to prefix the debug output with the call-id. The call-id however is very long and I'd like to cut it down and only display a portion of it.
