Re: std::string and case insensitive comparison

Hi,

what is the most efficient way of doing a case insensitive comparison ?
I am trying to write a universal String class and I am stuck with the case
insensitive part :

TCHAR is a char in MultiByte String env (MBCS)
and wchar_t if UNICODE

#if defined(WIN32) || defined(UNDER_CE)
typedef std::basic_string<TCHAR, std::char_traits<TCHAR>,
std::allocator<TCHAR> > tstring;
#else

#endif
#endif

class String : public Object
{
private:
tstring m_str;

public:
String(){}

String(LPCTSTR lpsz)
{
m_str = lpsz;
}

String(tstring str)
{
m_str = str;
}
// Comparison
int Compare( LPCTSTR psz ) const
{
return m_str.compare(psz);
}

int CompareNoCase( LPCTSTR psz ) const
{
???
}

// Convert the string to lowercase
String& MakeLower( LPCTSTR psz )
{
std::transform(m_str.begin(), m_str.end(), m_str.begin(), tolower);
return *this;
}

}
