While rewriting that function, I used the parameter names described on MSDN.
I don't see a point in inventing new parameter names for documented

Well, this is the variable naming convention used by most Win32 developers.
Also there are a lot of other components in Wine using this coding style,
just look for example in "notepad" or "regedit".

if(mbchar && !wchar) --> Put a NULL character into mbchar and return 1 as
if(!mbchar && wchar) --> Return the length of wchar
You might think that (!mbchar && !wchar) should now return 1 as the length
of a NULL character, but MS seems to have put a check here and returns 0 in
These behaviours are also covered by some of the added tests in the 4th
