Based on what you've given us, I'd say the above declaration is also correct. If I were to hazard a guess as to what the problem is it would be that the declaration of the structure should indicate a pointer to the structure member identified as the char type. That's strictly a guess, but it would explain the invalid parameter message since, in this case the structure itself would only be 32 bytes long.
