Example program

The attached example succeeds on the Microsoft implementation but fails under
Mono.

> "An application can set the ParameterValuePtr argument to a null pointer,

> (This applies only to input or input/output parameters.)"

*StrLen_or_IndPtr is neither of those things in this case, so the exception
does not apply.  As far as I can see the caller is not free to set to
ParameterValuePtr to a null pointer just because the data happens to be 0 bytes
long.
