port as interface argument?

[myndideal]

Hi,

is it possible to give a port to a handler/interface function on argument list?

Code: Select all

interface ia{  {unsigned} pop(out port ?debugpin);}; ...case i.pop(out port? debugpin) -> {unsigned res}: {  debugpin<:1;  res= doSomething();  debugpin<:0;}...debugpin<:0;result=a.pop(debugpin1);debugpin<:1;

It is compiles without errors, but it sends ET_ILLEGAL_RESOURCE on "case" line ... The handler and the caller is on the same tile, of course. There's no other tasks have a business with this debug pin at all. So, this would be a special use case, only for measuring or tracing the  operation...

I can't give the port from the function argument of the handler's main-loop, because in this case more than one par{} function will contains the same port. Yep. But the above example could touch the resource only sequentially because of the interface, I guess.

What is what I skipped? How can I do this similar way?

Hello, I am not sure if you can use port as an interface argument. Please check the attached example code which might serve your purpose! Hope this helps!
