In Ada 83, there was no official method --- for obtaining exception information, but a number of vendors supplied --- routines for this purpose, and this package closely approximates the --- interfaces supplied by DEC Ada 83 and VADS Ada. - --- The routines in this package are associated with a particular exception --- handler, and can only be called from within an exception handler. See --- also the package GNAT.Most_Recent_Exception, which provides access to --- the most recently raised exception, and is not limited to static calls --- from an exception handler. - -package GNAT.Current_Exception is - pragma Pure; - - ----------------- - -- Subprograms -- - ----------------- - - -- Note: the lower bound of returned String values is always one - - function Exception_Information return String; - -- Returns the result of calling Ada.Exceptions.Exception_Information - -- with an argument that is the Exception_Occurrence corresponding to - -- the current exception.
