What's the easiest way to tell if a wchar_t is alphanumeric?

unsigned int dwLength = wcslen( str );
	
for( unsigned int i = 0; i < dwLength; i++ )
{
	wchar_t cChar = str->GetAt( i );
	
	// what now?? any suggestions?
}

thanks

looks like ::isalpha( ) is a good start

The suitable functions are std::iswalnum() from <cwtype> or std::isalnum() from <locale>
