If you're looking for edge triggering, you can use poll(). That's what I used for GPIO and it worked fine.
http://raspberrypi.stackexchange.com/questions/3440/how-do-i-wait-for-interrupts-in-different-languages http://manpages.courier-mta.org/htmlman2/poll.2.html If I remember correctly, the first trigger is "garbage" and can be just thrown away, but after that, it will trigger every time GPIO goes up or down, depending on how you set it. This is done in kernel space, and if you use TOP, you'll see it does not actually poll constantly.
