Grabing Class and function name for use in a libraries

[eluser]The Casual Bot[/eluser]
hi all,

im trying to make a auth libary that will allow and diallow access the controller and function

so i trying to get the class and function name and the easy way i could think of doing this was the uri class but this seems to just return '0'

any ideas / suggestions how i can do this

i now i can pass the name in a var but want to try to avoid that
