linked list problem

Hi,
I have the following singly linked list:

typedef struct Dir
{
   // some space to hold data here
   void *next;    // have to take void * here cause Dir* leads to compile 
error
}DIR;

In my code:

DIR *temp = parentDir;    //parentDir is allocated initially but its 
next is not allocated at this point
while (temp)
{
   temp = (DIR*)temp->next;    //here next is null so, temp now is null
}
temp = newDir;        //here newDir is already allocated, but temp doesn't 
get allocated, in a way parentDir->next remains null.


While this type of code works fine on VS2005, it doesn't wprk here in 
cocoa.
How else can I reach the end of the list and add a new node?

Please help.

Thanks,
Nick
