what's the .h file should I include to use _tstof(), alternative of atof() ?

[flyingxu]

I see from msdn that the generic mapping of atof() is _tstof(), but I can't use it even after I include & . So, which .h file should I include?:confused: MSDN: TCHAR.H routine _UNICODE & _MBCS not defined _MBCS defined _UNICODE defined _tstof atof atof _wtof -- modified at 21:20 Wednesday 17th May, 2006

You need tchar.h.

It's very strange that I can use _tstof() in VS.net 2003 but not VC6, even I include the file tchar.h. Maybe I need the latest Platform SDK?:wtf:
