Basically parameters in the .spec files are used as descriptors for
relay debugging, and difference between ptr and wstr is whether the
contents on the buffer or just a pointer should be printed.

First parameter of wcscpy_s is a not initialized buffer, while first
parameter of wcscat_s is an initialized unicode string.
