AM335X: GPIO interrupt handler

Hi,

I'm using beaglebone REV A3 AM335x with arago image,

how i write a code to handle the GPIO interrupt ?

For your info, I've done the GPIO interrupt, by command " cat /proc/interrupts " :

......

76:         0      INTC        rtc0
208:       7      GPIO 

which i've trigger 7 times the GPIO interrupt. but how i write a code to handle the interrupt ?

Thanks & Regards
