I was develop a application which using VB as interface
design and C-Dll as enginer. Now I wish to portal some
of the code to a C-langauge Dll, but one of the functions
should return a Link-List,something looked like this:

int ToWhere
int FromWhere
int Color
Node NextNode

I used Link List because the number of nodes is not fixed one.
How to pass LInk-List object (Class) back to my VB program.
