// ----------------------------------------------------------------------------
// WX_DEFINE_VARARG_FUNC* macros
// ----------------------------------------------------------------------------
// This macro is used to implement type-safe wrappers for variadic functions
// that accept strings as arguments. This makes it possible to pass char*,
// wchar_t* or even wxString (as opposed to having to use wxString::c_str())
// to e.g. wxPrintf().
//
// This is done by defining a set of N template function taking 1..N arguments
// (currently, N is set to 30 in this header). These functions are just thin
// wrappers around another variadic function ('impl' or 'implUtf8' arguments,
// see below) and the only thing the wrapper does is that it normalizes the
// arguments passed in so that they are of the type expected by variadic
// functions taking string arguments, i.e., char* or wchar_t*, depending on the
// build:
// * char* in the current locale's charset in ANSI build
// * char* with UTF-8 encoding if wxUSE_UNICODE_UTF8 and the app is running
// under an UTF-8 locale
// * wchar_t* if wxUSE_UNICODE_WCHAR or if wxUSE_UNICODE_UTF8 and the current
// locale is not UTF-8
//
// Note that wxFormatString *must* be used for the format parameter of these
// functions, otherwise the implementation won't work correctly. Furthermore,
// it must be passed by value, not reference, because it's modified by the
// vararg templates internally.
//
// Parameters:
// [ there are examples in square brackets showing values of the parameters
// for the wxFprintf() wrapper for fprintf() function with the following
// prototype:
// int wxFprintf(FILE *stream, const wxString& format, ...); ]
//
// rettype Functions' return type [int]
// name Name of the function [fprintf]
// numfixed The number of leading "fixed" (i.e., not variadic)
// arguments of the function (e.g. "stream" and "format"
// arguments of fprintf()); their type is _not_ converted
// using wxArgNormalizer<T>, unlike the rest of
// the function's arguments [2]
// fixed List of types of the leading "fixed" arguments, in
// parenthesis [(FILE*,const wxString&)]
// impl Name of the variadic function that implements 'name' for
// the native strings representation (wchar_t* if
// wxUSE_UNICODE_WCHAR or wxUSE_UNICODE_UTF8 when running under
// non-UTF8 locale, char* in ANSI build) [wxCrt_Fprintf]
// implUtf8 Like 'impl', but for the UTF-8 char* version to be used
// if wxUSE_UNICODE_UTF8 and running under UTF-8 locale
// (ignored otherwise) [fprintf]

// like c_str()). It also converts format string to the correct form that
// accounts for string changes done by wxArgNormalizer<>
//
// Note that this class can _only_ be used for function arguments!
