[Serusers] tls, xlog and select framework syntax

[Klaus Darilion]

Hi!

I want to log some TLS parameters. I've tried:
   xlog("L_ERR","@tls = %@tls (String description of the TLS layer)\n");

but all I get is:
   ser[20222]: @tls = <null>tls (String description of the TLS layer)

using avps it works:
   %avp1=@tls;
   print_sattr("avp1");
   xlog("L_ERR","avp1 = %$avp1\n");


What is the correct syntax for using the select framework?

thanks
klaus
