Hi.
VC has a macro: __T() that's suppose to make life easier when switching between unicode/mb builds.
What does it do? I thought it'l map to L on unicode builds, but according to the sources - it just maps to nothing.

What's up?

You are right:

#define __T(x)      L ## x

the above line can be found in 'tchar.h' - the catch it that

#define __T(x)      x

This is controlled by the 'UNICODE' symbol that has to be defined or not, depending on what you want to use. In short:

#ifdef UNICODE
#define __T(x)      L ## x
#else
#define __T(x)      x
#endif

('tchar.h' boiled down to '__T()' ;-)

Feel free to ask if you need more information

Hmm yea.
I guess I missed that #if in the source file.
Thanks.
