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?
There is no way the code you show works for any C compiler, let alone
VS2005. You never do the linking part of the linked list.
In particular, the (effective) code sequence
A = B;
B = C;
does not set A to C in any language I'm familiar with.
Also, I'd recommend against naming any type DIR, as there's a libc
type by that name in <dirent.h>.
