My test program used poll/select on edge successfully. But I could not test 
the raising or falling feature actually, as my input is bouncing. So, it 
doesn't matter if I set both/raising/falling in edge, due to my inputs the 
effect is the same. Any input event will end in several raising and falling 
interrupts events.
I hope I could make this more clear.
