Question

I am creating application in AIR using JavaScript. Many of my functions requires text returned by native process. But native process, in AIR gives values asynchronously by calling function on STANDARD_OUTPUT_DATA Event.
Is there is any way to get that value synchronously, like waiting for a function till its execution is over.

Here is sample code :

   var textReceived;

   function callbackFunction()
   {
       textReceived= getTextfromProcess(); 
   }

   function chkProc()
   {
        process.addEventListener(STANDARD_OUTPUT_DATA, callbackFunction);
          //This is AIR's function which give text asynchronously 
   }
   function sqlExc(sql)
   {

   chkProc();
       //wait here before returning
   return   textReceived;
   }

As JavaScript runs on single thread, I can not use infinite loop with break.
Is there any way of achieving this?

NativeProcess has no blocking (synchronous) methods. BTW, infinite loop would not help here – to let runtime go process events, client code must exit all functions. Only after client code is finished in current frame, runtime communicates with native process (and network, and everything else.)
