[Users] Variables

[Douglas Garstang]

Is there any useful information ANYWHERE about avp's? I mean, don't take this the wrong way, but I've never had so much trouble interpreting/finding documentation on a subject. I can't even find out how to print the value of an avp with xlog. Is this ACTUALLY DOCUMENTED anywhere? I finally found an example somewhere from a newsgroup posting and used:

xlog ("L_INFO","$avp($foo)");

but openser complains with:

Dec 15 13:21:01 bil-pdev-3 openser[24718]: ERROR:xl_parse_name: unknow avp alias"foo" 
Dec 15 13:21:01 bil-pdev-3 openser[24718]: XLOG:xdbg_fixup: ERROR: wrong format[$avp($foo)]!

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.
