How do I convert from _TCHAR * to char * when using C++ variable-length args?

Question

We need to pass a format _TCHAR * string, and a number of char * strings into a function with variable-length args:

inline void FooBar(const _TCHAR *szFmt,          


        

Answer 1

Usually it looks like the following:

char *foo = "foo";
char *bar = "bar";
#ifdef UNICODE
LogToFileW( L"Test %S %S", foo, bar); // big S
#else
LogToFileA( "Test %s %s", foo, bar);
#endif

Your question is not completely clear. How your function is implemented and how do you use it?
