#define MAKE_EXCEPTION	(	NAME,

Value:

namespace Except {                                          \
    class NAME : public PARENT {                              \
    public:                                                   \
      NAME() {AppendWhat(#NAME);}                             \
      NAME(const char* message) {AppendWhat(#NAME, message);} \
      NAME(const char* file, int line) {AppendWhat(#NAME, file, line);}     \
    };                                                        \
  }

A macro to build an exception class __name that is derived from __parent. The __parent class must be derived from Except::Base which provides the AppendWhat method. This macro builds an exception class that can be used:

/// MAKE_EXCEPTION(Child,Base);
/// ...
/// try {
///   throw Except::Child();
/// }
/// catch (Except::Base& ex) {
///   std::cout << ex.what << std::endl;
/// }
///
