C, and by extension Objective-C, do not have references in the C++
sense. You'll have to pass a pointer to the thing that you want your
method to be able to modify.

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
