i'm trying to use xavps in new version of t serial functions and have a couple of questions: - when xavp value of type SR_XTYPE_STR is added using xavp_add_value function, do i need to make a copy of the string using pkg_malloc? in normal avps this is not needed, but for some reason a copy is made in sql_api.c. - what is xavp equivalent of usr_avp avp_destroy, which takes one argument: pointer to usr_avp to be destroyed? there is xavp_rm, but it takes two arguments and i didn't find from the sources any example of its use. -- juha
