#define DEFINE_STANDARD_EXCEPTION	(		C1,
			C2
	)

Value:

\
class C1 : public C2 { \
  void Throw () const Standard_OVERRIDE { throw *this; } \
public: \
  C1() : C2() {} \
  C1(const Standard_CString theMessage) : C2(theMessage) {} \
  static void Raise(const Standard_CString theMessage = "") { \
    Handle(C1) _E = new C1; \
    _E->Reraise(theMessage); \
  } \
  static void Raise(Standard_SStream& theMessage) { \
    Handle(C1) _E = new C1; \
    _E->Reraise (theMessage); \
  } \
  static Handle(C1) NewInstance(const Standard_CString theMessage = "") { return new C1(theMessage); } \
  DEFINE_STANDARD_RTTI_INLINE(C1,C2) \
};

Defines an exception class C1 that inherits an exception class C2.

C2 must be Standard_Failure or its ancestor. The macro defines empty constructor, copy constructor and static methods Raise() and NewInstance(). Since Standard_Failure implements class manipulated by handle, DEFINE_STANDARD_RTTI macro is also added to enable RTTI.

When using DEFINE_STANDARD_EXCEPTION in your code make sure you also insert a macro DEFINE_STANDARD_HANDLE(C1,C2) before it.
