It can be used from Pure units. - --- There is no prohibition in Ada that prevents exceptions being raised --- from within pure units. The raise statement is perfectly acceptable. - --- However, it is not normally possible to raise an exception with a --- message because the routine Ada.Exceptions.Raise_Exception is not in --- a Pure unit. This is an annoying and unnecessary restriction and this --- package allows for raising the standard predefined exceptions at least. - -package GNAT.Exceptions is - pragma Pure; - - type Exception_Type is limited null record; - -- Type used to specify which exception to raise - - -- Really Exception_Type is Exception_Id, but Exception_Id can't be - -- used directly since it is declared in the non-pure unit Ada.Exceptions, - - -- Exception_Id is in fact simply a pointer to the type Exception_Data - -- declared in System.Standard_Library (which is also non-pure). So what - -- we do is to define it here as a by reference type (any by reference - -- type would do), and then Import the definitions from Standard_Library. - -- Since this is a by reference type, these will be passed by reference, - -- which has the same effect as passing a pointer. - - -- This type is not private because keeping it by reference would require - -- defining it in a way (e.g a tagged type) that would drag other run time - -- files, which is unwanted in the case of e.g ravenscar where we want to - -- minimize the number of run time files needed by default. - - CE : constant Exception_Type; -- Constraint_Error - PE : constant Exception_Type; -- Program_Error - SE : constant Exception_Type; -- Storage_Error - TE : constant Exception_Type; -- Tasking_Error - -- One of these constants is used in the call to specify the exception - - procedure Raise_Exception (E : Exception_Type; Message : String); - pragma Import (Ada, Raise_Exception, "__gnat_raise_exception"); - pragma No_Return (Raise_Exception); - -- Raise specified exception with specified message - -private - pragma Import (C, CE, "constraint_error"); - pragma Import (C, PE, "program_error"); - pragma Import (C, SE, "storage_error"); - pragma Import (C, TE, "tasking_error"); - -- References to the exception structures in the standard library - -end GNAT.Exceptions; |
