Thread: template function

I have 2 functions here that do almost the same thing. One converts a string to wstring and the other wstring to string. Somehow I think I should create one template function for this but dont see how to do it. Anyone else have an idea on how to do this?

Code:

static std::string wide_to_char(const std::wstring &ws)
{
	std::string s;

	for (std::string::size_type i = 0; i < ws.length(); i++)
	{
		char c;
		wctomb(&c, ws[i]);

		s.push_back(c);
	}

	return s;
}

static std::wstring char_to_wide(const std::string &s)
{
	std::wstring ws;

	for (std::string::size_type i = 0; i < s.length(); i++)
	{
		wchar_t c;
		mbtowc(&c, &s[i], 1);

		ws.push_back(c);
	}

	return ws;
}
