Put the & before the variable type:

- (UInt32) traverseTreeStraightReturnedDirection:(&int)treeDirection...

HTH,

Hi,
I have the following in my .m file:
- (UInt32)traverseTreeStraightReturnedDirection:(int&)treeDirection
			  returnedTreeDepth:(int&)treeDepth
				returnedKey:(HPlusCatalogKey&)catKey
				 lookForKey:(HPlusCatalogKey)lastKey
{
// code here
}
But the error when compiling is "parse error before & token". Is passing by reference not allowed or is there any other syntax that I should follow?
Thanks,
Nick
