It should almost always map to wstr.

As the general rule it depends on whether the
parameter is IN, OUT or IN/OUT.

IN: wstr
OUT: ptr
IN/OUT: wstr

PS. It is for debug messages. If the parameter is OUT
it might not be initialized as thus it should not
be printed as a string (in this case a wide string).
