Re: [Boost-users] [filesystem] basic_path as parameter

I'd like to use basic_path as a function parameter so that it works correctly whether a wide or narrow string is passed.

template<typename T> void func(basic_path<T> file) { do thing to file }

func("myfile"); func(L"myfile");

However I can't do this because basic_path has a second Traits template parameter which is not itself a template. So I tried the following workaround:

template<typename T> struct traits_chooser;

template<> struct traits_chooser { typedef boost::filesystem::path_traits traits; };

template<> struct traits_chooser { typedef boost::filesystem::wpath_traits traits; };

template<typename T> void func(basic_path file) {...}

But my compiler (MSVC 2005) still can't deduce the parameter type. Does anyone know how I can get this to work?

Try specializing for char and wchar_t instead of char* and wchar_t*. You could also just use template void func(const basic_bath& file); In Christ, Steven Watanabe
