dll call in uniface 9

Author: dylan.huart@gmail.com (Dylan)

Hello everyone, I'm trying to familiarize myself with the IDE UNIFACE 9 and its programming language, to make changes to an application. I developed a DLL in C it can return a path, so a char *, the called function takes no argument, I wanted to call this function from UNIFACE. I could see that we could use it to Activate call: Activate "NameOfDLL". NameOfFonction ($$ variable) I told my dll in signatures, but I is not nothing in return. my question is: What is $$variable returns the return of my function?   Thanks !
