call a controller function from another controller

[eluser]datguru[/eluser]
Hi there,

Just wondering if it is possible to call a controller function from another controller.. so for example say I have Controller 1 that has a function called function 1 and then I have controller 2. I want to be able to access function1 of controller 1 from controller 2. Is that possible? the reason I want to do this is because I have a generic function that I want a few controllers to use.

Thanks
