Hi guys I need some help. I am making a c++ embedded application in an ARM. I need to get a push button event, I was looking for in internet and I find that the best way to do it is with interruptions. I know that I can set one pin through terminal like this "echo raise > /sys/.../gpio/gpio81/edge". But I need to know how can I get the interrupt from my C++ application when it happend, I just need some example, because I do not know if I have to use some special library.
Thank you guys I hope someone can help me.
