how to get return value? #20

Closed xzwang2005 closed 7 years ago

The sample code didn't show how to retrieve the return value. What's the syntax for that?

Hello, in order to access signal return values you must use the syntax shown here: emit_accumulate. You have to use the emit_accumulate method and pass a lambda in order to access the return values.
