[Devel] Return parameters from module functions

[Bogdan-Andrei Iancu]

Hi Stefan,

retcode variable contain the result code of the last script 
function/instruction (so, not necessary of the last module function).

you should try to store the retcode immediately after your call to avoid 
to be overwrite:
   

        myFunction();
	avp_write("$retcode","$avp(i:10)");
	if (avp_check("$avp(i:10)", "eq/i:10")) {
		{ ... do something ... }
        else if (avp_check)
		 { ... do something else ... }


Most probably the 1 value you got is from the IF evalution :). You may 
also try a simpler approach, by using the switch command:

bogdan
