I'm sure I've read it somewhere but now cannot find out what I should do once my program has finished with WiringPi. Being a bit old fashioned I expect to give all the GPIO thingys back or make them safe when I've finished with them. As I'm also using the interrupt extentions I also feel these really should be handled correctly and at least turned off.
I've looked repeatedly at the WiringPi pages, still think I've read that I should do something but I'm stuffed if I can find anything. I would expect to find something in the Setup reference page but it only includes what I should do when/before I start.
I've also checked through a number of (but not all) of the WiringPi examples but found nothing.
So, clever people, what am I missing?
