Message        <Context> "<expression>" has a pointer type, but
                occurs in a context that expects a struct or union.

 Description    The left operand of the struct/union member operator
                (.) is a pointer type instead of a struct or union
                type.

 User Action    Specify the correct struct or union type object as
                the left operand.  In cases where the left operand is
                a pointer to a struct or union, it might be possible
                to use the struct/union pointer operator (->) instead
                of the member operator.
