Re: [sr-dev] couple of xavp questions

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.

you don't need to clone it to pkg, the xavp functions will make a clone to shared memory anyhow. Alex Hermann added the sql_xquery(), I don't know why he decided to clone, it is not necessary and the pkg-alloc'ed value is feed after the execution of xavp add function.

• 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.

An xavp can contain a list of xavps. If you delete from the root list, then provide NULL as second param.
