Extern wiringPiIsr(iPin As Integer, iEdgeType As Integer, pFunction As 
Pointer) In "lib..."

...

And then you use the name of a static function as 'pFunction' argument 
when calling wiringPiIsr.

Gambas will automatically create a internal callback that will execute 
the Gambas function through the interpreter as if it would be called 
directly like a C function.
