    X11 head to i2c bus

    Hello guys, it's been a while since I've last been here but I have a question for you.

    Let's say I have a multihead setup (3 displays for example)
    My function receives a head number an I have to communicate with it over i2c.
    How can I map the head number (0,1,2) to the i2c device filename?

    in my /dev/ directory I have the following device files:
    i2c-0
    i2c-1
    i2c-2
    ...

    How do I know which screen/head corresponds to which device file?
    And no the 'x' in i2c-x is not the head number

    Thanks

    Oh yeah gcc on red hat
