How can I use gpio port A?

Hello !:

I need to use gpio port A but I dont know how, I am using a devboard 82
with linux 2.4.20.
I know there is a device '/dev/gpioa' but when I try to write to
'/dev/gpioa' an error ocurrs ('Operation not permitted').
Do I need to include some headers in order to use any 'especial
function' to access port A?
