Well, that should work just fine. How did you define the struct?
You realize that each "struct {...}" defines a _unique_ struct,
even if it has the same members? Better use a named struct or a
typedef everywhere.

Maybe posting a simplified excerpt of your code would help.
Quite often the problem is solved during that process. :-)
