Interrupt functionality in C or Python

I've been looking through the example code in both C and Python looking to see if it's possible to set an interrupt callback on an input pin of the DIO module. Can you please advise if this functionality is currently available? All the code I've seen just uses infinite while loops to scan the input ...

Re: Node Red

Hey guys, I'm hanging out for the Jessie image :-)

My password had a y in it, so i had to press the z key instead of the y so i could login. A trap for noo...
