[OpenSIPS-Users] function with 6 parameters

Wed Apr 13 12:58:17 CEST 2011

Hi Razvan,

I've applied the patch you gave me.
This is the output:

INFO:core:do_action: called test6(0x81b1398, 0x81b144c, 0x81b14b4, 0x81b151c, 0x81b1584, 0x81b15ec)

This is the code from opensips.cfg:

$var(var1) = 111;
$var(var2) = 222;
$var(var3) = 333;

$avp(s:avp1) = 123;
$avp(s:avp2) = 456;
$avp(s:avp3) = 789;

test6("$var(var1)", "$var(var2)", "$var(var3)", "$avp(s:avp1)", "$avp(s:avp2)", "$avp(s:avp3)");

Attached is the module.

Thanks,
Bogdan

  Hello Bogdan,

    I implemented a similar test function that takes 6 parameters.

    All values seems to be in the correct order in both fixup function
    and triggered function.

    I attached a small patch that prints the value of the parameters
    right after the fixup function and then again before the function is
    called.

    Please apply this patch and then check if the parameters values and
    order match between the fixup and triggered function?

    Regards,

    Razvan

            Hi Bogdan,

              The "inversion" is only in the triggered function.

              The arguments are passed correctly from left to right to
              the fixup function.

              The triggered function is:

              test_function(struct sip_msg *msg, char *arg1, char *arg2,
              char* arg3, char* arg4, char* arg5, char* arg6)

              {

                  str arg1_s  = {NULL, 0};

                  if(arg1 == NULL || fixup_get_svalue(msg,
              (gparam_p)arg1, &arg1_s) != 0)

                  {

                      LM_ERR("Invalid arg1 argument\n");

                      return -1;

                  }

              .........

              }

              arg1_s.s has the value of arg6_s.s while arg6_s.s has the
              correct value.

              Thanks,

              Bogdan

                 Hi Bogdan,

                  This "inversion" is visible in the fixup function or
                  is the triggered function ?

                  Regards,

                  Bogdan

                          Hi
                            everyone,

                            I implemented an OpenSIPS custom module that
                            communicates with an external application.
                            From the routing script I call a function
                            with 6 parameters:

                            test_function('$fU', '$tU', '$ci',
                            '$avp(s:name1)', '$avp(s:name2)',
                            '$var(name3)')

                            The problem is that when the corresponding
                            function is called in C, the first parameter
                            gets the value of the last one.

                            This doesn't happen when the function is
                            made to take 5 parameters.

                            The fixup function that I use is this:

                            static int pvn_fixup_spve_spve_6(void**
                            param, int param_no)

                            {

                                if (!(param_no >= 1 &&
                            param_no <= 6))

                                {

                                    LM_ERR("invalid parameter number
                            %d\n", param_no);

                                    return E_UNSPEC;

                                }

                                return fixup_spve(param);

                            }

                            Is there something wrong with it or the
                            problem is elsewhere ?

                            Thanks,

                            Bogdan
