digitalmars.D.announce - Heads Up: Use WCHAR when interfacing with Windows

reply Walter Bright <newshound2 digitalmars.com> writes:
Due to name mangling changes required by compatibility with C++11, wchar_t will 
no longer mangle the same as wchar. Yes, I know, argghhh. What this means for 
Windows API calls is that the alias for WCHAR will change from wchar to wchar_t.

To get a head start on this, when you're writing interface code to Windows, use 
WCHAR instead of wchar or wchar_t, and then your code will continue to compile 
before and after the change.

Here's an example:

Could you please reply to my GitHub comments? I feel like all 
this is seriously underdocumented, and I don't understand why 
many of these changes are necessary.

I agree, this makes zero sense to me. Windows functions are 
mangled Name size - the specific types are irrelevant.
