Hi, thanks.
Are you suggesting to replace the macro with something like the following?
#define taskLoopType extern xTaskHandle
It works too (I have compiled it, changing the example too).
The macro is only for forward declarations when needed, I expect that most sketches will never use it, but right now I'm not sure which is more easy to understand. I like both!
Good question to decide as a community...
Regards,
Julián
