Hi Jose,

Thanks!

I am unit testing radar service code, Calling verb callback function "virtual_read" but its failing because I am returning integer from that function. I could see callback has void return type but as I am doing unit testing(by googletest framework) of code need something to return to verify pass/fail. I tried something on external typecasting & void pointer also, Is there any way we can return?

reference log:

 tests/../src/radar_service.c: At global scope:
tests/../src/radar_service.c:1238:21: error: invalid conversion from 'int (afb_req_t)' {aka 'int (afb_req*)'} to 'void (afb_req*)' [-fpermissive]
