Setting items in perl and accessing them in C

Hello I have the perl module enabled and customized to my needs. Inside it, I add a new attribute called token in the authorize function $RAD_CHECK{'token'} = 'mytoken'; . So, when executing it I see in the debug output (-X parameter) something like: ... Added pair token = mytoken ... Apart from this, I' ve modified the function eappeap_success (file peap.c) so I can add a TLV (the token) inside the success packet and send it to the client. My question is, how can I get the $RAD_CHECK{'token'} value inside the eappeap_success function? I've seen the structures handler (EAP_PEAP type) and tls_session (tls_sesion type) but I only find values related to the request, not to the response or radcheck arrays. Thanks!
