Re: [sr-dev] how to assign value to a pvar?

it was easy to write the code that counts the number of record routes in a message. first i though that i can return the count as result of the script function, but that didn't work out because if script function returns 0, it will terminate execution of the script. so i though to give the function a pvar argument to which the count is stored, e.g., rr_count("$var(count)"); so far i have not been able to assign the count to the pvar argument and have already spent three hours on such a simple assignment statement. in pvar.h there is function int pv_set_spec_value(struct sip_msg* msg, pv_spec_p sp, int op, pv_value_t *value); that sounds like it might do the trick, but there is no documentation on op argument and i have not yet found in sr sources any place there that function is really used. also i have not found in any of sr modules any script function that would assign something to a pvar argument? is there one so that i could take a look or it that an impossible thing to do? i have tried various versions, such as pv_val.ri = count; pv_val.flags = PV_VAL_INT; if (_count) { if (pv_set_spec_value(msg, (pv_spec_t *)_count, EQ_T, &pv_val) == 0) { where _count is pvar fixed up argument of rr_count function, but no luck so far. i just get Nov 10 05:42:51 localhost /usr/sbin/sip-proxy[27707]: ERROR: pv [pv_svar.c:117]: out of pkg mem! Nov 10 05:42:51 localhost /usr/sbin/sip-proxy[27707]: ERROR: pv [pv_core.c:1620]: error - cannot set svar [tmp] can anyone help here? if not, i'll have to make rr_count to return the actual count + 1 so that i can return it as result of the rr_count function. -- juha _______________________________________________ sr-dev mailing list sr-dev(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
