performSelector with reference

I have a selector that I want to execute. One of the parameters is a 
**NSError. It doe not like the pointer to the pointer. It wants an 
object. I could just cast if but I wanted to see if there was a 
cleaner way of doing this.

I'm using "- (id)performSelector:(SEL)aSelector withObject:(id)
object1 withObject:(id)object2;"

My **NSError is in the second parameter.

thanks for the help
