Why is the return values of decoder_direction_and_count_with_fm_signal function not being returned in the above program?

You get the outputs from the job in

data=getAllOutputArguments(pjob);

But you never do anything with "data" to display the results.

e.g.

>> data = pjob.getAllOutputArguments

data = 

      'task one output'
      'task two output'

>> data = pjob.getAllOutputArguments;

U r right about not using data.but I'm not getting data from taskone. I asked about that.

I'd imagine something isn't getting into the logical bucket you think it should be going into. You could attack that by using the debugger and breakpoints, or by inserting statements that set the value and see if they are returned. You could also comment all your logic out and then just set values for the return, to make sure it does come back, and work from there.

I'll also caution about the use of "i" as an iterator, as "i" has a very distinct mathematical meaning. You should likely use "ii" to distinguish between the two and avoid confusion.

I have a problem to solve.. ,it will be helpful if u can help.

I have 3 functions or programs which are to be run simultaneously on a quad core processor such that function1 is to be run on core0, function2 on core1 and function3 on core2 and core3 is left for other processes.

Please help if u can.

I regret that I don't have the time to step through and debug your code -- I have some projects I must make progress on for my daily work. You really should be able to find where the error is with standard debugging techniques.

Also, there is no guarantee of what core your task is going to end up executing on. That is left up to the operating system entirely.
